FOREWORD

Development is a continuous process and in that process development of technology helps in the

optimum use of resources to meet the need of ever growing demand. Water is a vital resource which is required to sustain life on earth. Growing population, industrialization, upgradation of standard of living put huge pressure on water as a resource.

Irrigation sector consumes 92 % of water; hence, increasing efficiency in water application in irrigation sector will immensely save water. Micro irrigation is most efficient form of water

application method. Therefore, micro irrigation is the future vital area to be explored and practiced in U ttar Pradesh.

The future revolution in agriculture will come from precision farming. Micro-irrigation can, indeed, be the stepping stone for achieving the goal of making farming sustainable, profitable and productive.

To implement the micro irrigation system 'Guidelines for Planning and Design of Micro Irrigation System" has been prepared by Central Design Directorate, Lucknow. These guidelines will be helpful in providing the opportunity to new users who require technical knowhow in design and establishment of

the system. It will also be helpful in maintaining the uniformity of quality.

These guidelines have been prepared by the Central Design Directorate under the leadership of Er. AK Jain, Level - I (D & R). It is hoped that the guidelines will be helpful for designers and field engineers.

FOREWORD

UP state has 161. 70 BCM of surface water and 72 BCM exploitable ground water. Because of

increasing demand for various purposes namely irrigation, drinking and domestic, power, industrial and other uses, its scarcity is becoming apparent which shall get more pronounced with increasing population. The indiscriminate use of ground water has resulted in depletion of groundwater storage and lowering of water levels in certain areas on one hand,on other hand, the surface water canals, in areas having shallow water level, have resulted in water logging and soil salinisation. With continual diminishing per capita water availability coupled with groundwater exploitation, it has become imperative to switch to efficient water saving technologies and alternative methods of irrigation.

Flood irrigation has been predominantly used for field crops, where water losses from evaporation and leaching are very high. As a result of the water saving campaign in recent years, the development of micro irrigation system has been recognised. Micro irrigation system can be of immense help in reducing a bit of the burden. This system is effective in saving water and increasing water use efficiency as compared to the conventional surface irrigation methods. Additionally, it also helps in minimizing soil erosion.

To implement the micro irrigation system "Guidelines for Planning and Design of Micro Irrigation System" has been prepared by Central Design Directorate, Lucknow under the leadership of Er. A K Jain, Level - I (D & R). These guidelines not only give the methodology but also provide the specification of various elements of design & equipment, to our designer and field engineer.

I hope this manual will be of great use for the department & it will help in optimizing the scarce resource i.e. water.

FOREWORD

Water is essential for sustainable development of human beings specially for drinking, agriculture, health, sanitation, construction etc. Around 92 % available water resources are being utilized in agricultural irrigation sector. Conventional canal systems tubewells, tanks are widely used to carry water from naturally occurring sources, to farmer's field. There is huge wastage of water in traditional irrigation methods like flood irrigation etc. So, it is required to develop technology which can help in optimal utilization of water and its transportation from source to field. For this, we need to change conventional system to piped network system.

Micro irrigation system can be of immense help in reducing a bit of the burden. This system is effective in saving water and increasing water use efficiency as compared to the conventional surface irrigation methods. Additionally, it also helps in prevention of growth of unwanted weeds and soil eros10n.

To implement the micro rrngation system "Guidelines for Planning and Design of Micro Irrigation System" has been prepared by Central Design Directorate, Lucknow. These guidelines will be helpful in providing the opportunity to new users who require technical knowhow in design and establishment of the system. It will also be helpful in maintaining the uniformity of quality.

These guidelines for planning and design of Micro Irrigation System have been prepared by the Central Design Directorate under the leadership of Er. A K Jain, Level - I (D & R). It is hoped that the guidelines will be helpful for designers and field engineers.

PREFACE

U P has a vast network of canals, tubewells and tanks which are used for inigation purpose. Canal system and Guls (water course) are essential components of this system which are used to carry irrigation water from source to field. Farmers broadly use flood irrigation system to irrigate their fields. This process leads to wastage of water in the form of conveyance loss, percolation loss, evaporation loss, loss due to breach and loss due to negligence. Excessive use of water is not only harmful for the yield of plants but also invites the danger of water logging where water table is high.

Micro inigation system is useful in optimising the yield of crops Uustify the slogan 'Per Drop More Crop') and minimise the losses which are inevitable in conventional system. Micro irrigation is the slow application of continuous drips, bubbler, subsurface or sprays of water above or below the soil surface. This system is most suitable for water scarce areas and in hilly terrains where ground is uneven and undulating. Besides, it helps reduce water consumption, growth of unwanted plants (weeds), soil erosion and cost of cultivation.

Until now, there was no formal guideline available for the U P Irrigation Department for micro irrigation systems. Officers of Central Design Directorate, Lucknow have prepared a comprehensive guidelines for planning and design of micro irrigation system. Er. Anil Kumar Niranjan, S.E., Er. Kamnesh Kumar and Er. Alok Kumar (Executive Engineers) and Er. Alok Kumar and Er. Varsha Bisht (Assistant Engineers) have made valuable contributions in preparing these guidelines.

These guidelines cover introduction, objectives, types, benefits and limitations of Micro Irrigation Systems. It also covers planning and designing, running and maintenance of Drip and Sprinkler Irrigation and its components under Micro Irrigation System. These guidelines also include indicative bill of quantities for drip and sprinkler irrigation systems for reference alongwith crop specific design examples as annexures. Various IS Codes and other government sources have been referred for preparation of these guidelines.

It is hoped that these guidelines will be helpful for both design and field engineers in designing and execution of micro inigation system related projects.

INTRODUCTION

In 2015, Government of India launched Pradhan Mantri Krishi Sinchayee Yojana

(PMKSY). The scheme aims at creating protective irrigation by harnessing rain water at micro level

through ‗Jal Sanchay‘ and ‗Jal Sinchan‘. Micro irrigation is an integral component of the scheme to

maximise water use efficiency at farm level.

State of Uttar Pradesh has bounty of water resources, but not all water resources are

utilizable. Rainfall is mainly limited to monsoon season. Due to plain topography of the state, large

storage of water is not feasible. We do divert certain amount of water coming from upper riparian

states but that does not suffice the demand. Due to excess abstraction, ground water is depleting very

fast and many regions have already gone into dark zone resulting rivers going dry in lean season.

Because of all these physical and topographical constraints there is little scope of augmentation of

water resources and supply side management of water resources.

So, demand side management is only option left now. Demand side scenario of the State is

such that almost 92 percent water consumption is in agriculture sector. Further within agriculture

sector, 85 percent water is consumed by only three crops that are wheat, paddy and sugarcane. All of

these crops are water guzzling crops. However, farmers produce these crops because of remunerative

prices and ready market is available for these crops. Food security and farmers‘ income are twin

objectives of any state agricultural policy but sustainability of resources is also imperative keeping in

mind requirements of future generations. So, we have to take immediate steps to reduce water

consumption in agriculture sector ensuring sustainability without compromising food security or

farmers‘ income.

To reduce water demand we need to shift to less water intensive crops along with

promoting micro-irrigation. However, judicious use of micro irrigation is imperative to draw real

benefits from this technology. While sprinkler irrigation is suitable for any type of crop in undulating

terrains such as Bundelkhand, its use in plains in wheat crop may not help any net water saving

because saving in seepage part is tantamount to reducing recharge of ground water by same amount.

Further, evaporation losses are rather more in sprinklers so there is no saving on that part too.

However, other benefits of micro-irrigation including sprinkler do entail use of these systems in large

scale in the state of Uttar Pradesh. Heavily silted canal water may not be best option for micro-

irrigation but there are thousands of state and private tube-wells and also lift canals where these

systems can be used extensively.

TYPES OF MICROIRRIGATION

Micro irrigation is the frequent application of small quantities of water on or below the soil

surface as drops, tiny streams or miniature spray through emitters or applicators placed along a water

delivery line. Micro irrigation encompasses a number of methods or concepts such as bubbler, drip,

trickle, mist or spray and subsurface irrigation.

1. Bubbler Irrigation

The application of water to the soil surface as a small stream or fountain, where the

discharge rates for point source bubblers, emitters are greater than for drip or sub surface

emitters but generally less than 225 lit/hr. Because the emitter discharge rate normally

exceeds the infiltration rate of soil, a small basin is usually required to contain or control

the water.

Bubbler Irrigation

2. Drip and Trickle Irrigation

The application of water to the soil surface as drops or tiny streams through emitters. Often

the terms drip and trickle irrigation are considered synonymous. For trickle and drip

irrigation, discharge rates for point source emitters are generally less than 16 lit/h for single-

outlet emitters and discharge rates for line-source emitters are generally less than 16 lit/h/m of

lateral.

The pressure that needs to be maintained at the emitters or drippers, also called operating

pressure, is usually small operating pressure 1 to2 kg /cm2 compared to the operating pressure

7

at nozzle of the sprinkler irrigation system.

Drip Irrigation (Surface)

3. Spray/ Sprinkler Irrigation

The application of water by a small spray or mist to the soil surface, through the air.

Discharge rates for point-source spray emitters are generally lower than 175 l/h. The sprinkler

irrigation is one of the pressurized irrigation methods, in which water is sprayed into the air

and fall on the ground. The spray of water is developed by the flow of water under pressure

through small orifices or nozzles.

However, there are distinct differences in the water flow rate, operating pressure requirement

and measurement of the wetted area between drip and sprinkler irrigation systems.

Sprinkler Irrigation

8

4. Subsurface Irrigation

The application of water below the soil surface through emitters with discharge rates

generally in the same range as drip irrigation. This method of water application is different

from and not to be confused with the method where the root zone is irrigated by water table

control, herein referred to as sub irrigation.

DRIP IRRIGATION

SYSTEM

CHAPTER 4

DRIP IRRIGATION SYSTEM

Drip Irrigation system is the latest method of Irrigation. It is an efficient method of

application of water at the plant bottom at a rate nearly equal to the consumptive use rate of plant.

Thereby minimising the conventional water losses like percolation , runoff and evaporation from

soil. This method has been found to be highly successful in distant crops like mango, grape, papaya,

orchard, etc.

Drip irrigation system can be classified into the following:

(i) Surface drip irrigation

(ii) Sub-surface drip irrigation

(iii) Family drip

(iv) Online drip

(v) In-line drip

Surface drip irrigation

Surface drip irrigation is used to irrigate perennial crops (plants that live for more than two

years) and annual crops (plants that germinate, produce seeds, flower and die in one year).

Sub-surface drip irrigation

Sub-surface drip irrigation is a method of irrigating crops through buried plastic tubes,

containing embedded emitters located at regular spacing. A subsurface drip irrigation system has a

similar design as surface drip irrigation system. But in this case, the drip tubes are typically located 1

– 2 m apart and 15 – 25 cm below the soil surface. In sub-surface drip irrigation, evaporation is

minimized and water is used more efficiently as compared to surface irrigation. In sub-surface

irrigation, the effects of surface infiltration, water losses via evaporation and surface run-off are

eliminated. Water is applied directly to the root zone of a crop as opposed to surface irrigation, in

which most weed seeds hibernate. Water application is efficient and uniform in this system.

Family drip or gravity fed drip irrigation

Family drip or ‗gravity fed drip irrigation‘ system is a low-cost system developed for small

family plots. It is suitable for house gardening and peri - urban agriculture. It can also be used to

demonstrate the working of drip irrigation system. Family drip system is designed for areas

13

measuring 500–1000 m2. It consists of five components — elevated tank, shut-off valve, filter, main

line and drip line. Generally, a family drip irrigation system comprises a drum, control or shut-off

valve, filter (small disc or screen filter), main line and drip laterals. The drip outlets are spaced at 30

cm. No central pressurized water system or power source is required in this system. Therefore, it is

cheap, easy to install and operate.

Family Drip System

Online drip irrigation

In this system, emitters or drippers are fixed externally on the laterals at designed

spacing. Thus, the drippers can be checked and cleaned easily in case of clogging. The dripper

spacing can be changed any time to cover the increased root zone of a plant. Online dripper

system is used in orchards, vineyards, artificial landscapes and nurseries. It is, generally, used for

irrigating horticultural plants like mango, coconut, orange, lemon, banana, grapes, pomegranate,

papaya, guava, teakwood, bamboo, amla, etc.

Online drip irrigation

14

In-line drip irrigation

In this system, drippers are fixed in the lateral tube at designed spacing at the time of

manufacturing to meet the requirement of various crops. It is effective for row crops like cotton,

sugarcane, groundnut, vegetables and flowering crops. Dripper spacing depends on the water.

In-line drip irrigation

4.1 BENEFITS OF DRIP IRRIGATION SYSTEM

High water use efficiency up to 95 percent ( 50 to 70 percent water saving)

As water is applied locally and leaching is reduced, wastage of fertilizer is minimized.

Low weed growth.

Can be used in rough areas without leveling.

Inter cultivation with Irrigation.

Labour and manpower saving

Increase in plant growth & yield.

15

4.2 COMPONENTS OF DRIP IRRIGATION

Pump unit

The pump unit lifts water and produces the desired pressure for distributing water through

emitters.

Head control unit

It consists of valves to control the discharge and pressure of water in the entire system. It

may also have filters to clean the water. The head control unit turns the automatic valves on or off

through control signals.

Automatic control valve

Valves allow to turn different sections on and off automatically.

16

Gate valve

Gate valves may be used in place of electric valves to turn different sections on or off.

They are manually operated isolation valves.

Flush valve

It is a self-opening valve that allows lines to be flushed when the pipe pressure is low. It

shuts when the pressure builds up.

Automatic air release valve

Automatic air release valves (ARV) are used to displace air contained within an irrigation

system, which can adversely affect its performance.

Check valve

A check valve, also called ‗non-return valve‘, is a mechanical device in a pipe that permits

the flow of water in one direction only. It prevents the backward flow of water.

Pressure reducing valve

It is commonly used when installing a drip irrigation system or where high pressures can

pose a problem.

Filter

Common types of filter include screen and graded sand filters, which remove fine material

suspended in water. Filters come in different volume capacities and mesh sizes (filtration particle

exclusion capacities).

Screen filter

It uses a fine mesh formed into a column to filter out undesirable elements from water.

Mains, sub-mains and laterals

Main lines, sub-mains and laterals supply water from the control head into the fields. They

are, normally, made of flexible material, such as PVC pipes. Laterals or drip lines are small diameter

(1–1.25 cm) flexible lines made of Low Density Polyethelene Pipes (LDPE). Generally, the main and

sub-mains are laid across the slopes, while laterals are placed along the slopes. If a field is divided

17

into sub-block, each block is provided with one sub-main and a control valve. Based on the available

data of water capacity, water requirement of a plant and pressure required at the lateral layout,

designs for the micro irrigation system are made. Laterals are, normally, laid parallel to each other.

There is, usually, one lateral line for each crop row.

Emitters or drippers

These are fixed at regular intervals in the laterals. They are, usually, spaced more than 1 m

apart. For row crops, more closely spaced emitters may be used to wet a strip of soil. They supply

specified quantity of water to plants in a field. Water is delivered at or near the root zones of plants,

drop-by-drop. The PVC valves allow water to flow at a slow rate (2–16 litre per hour) and in various

shapes and designs. Emitters are selected on the basis of soil texture and crop root zone system. To

measure the anticipated variations in the discharge of water in emitters, a pressure gauge is used.

4.3 PLANNING AND DESIGN OF DRIP IRRIGATION SYSTEM

The planning and design of drip irrigation system is essential to supply the required

quantity of irrigation water to the crop at a desired uniformity. The main purpose of the design of drip

irrigation system is to decide the dimensions of various components of the system such that the

system provides the require quantity of water at the desired uniformity in application while keeping

the cost of the system to minimum. To apply the desired amount of water at nearly uniform rate to all

the plants in the field, it is essential to design the irrigation system that maintains a desired hydraulic

pressure in the pipe network and provide the desired operating pressure at the emitter. The design of

drip irrigation system consists of selection of emission devices, size of laterals, manifolds, sub main,

main pipeline, filter and pump. The system design depends on many factors, but the design will be

constrained by several economics factors such as feasibility, initial investment, labour, return on

investment and performance parameters such as the rated flow rate and desired emission uniformity.

The steps to be followed for designing the drip irrigation system are given below:

1. Inventory of the resources and data collection.

2. Computation of peak crop water requirement

3. Deciding the appropriate layout of the drip irrigation system

4. Selection of emitters

5. Hydraulic design of the system in terms of lateral, sub main and main

6. Horse power requirement of pump

1. Inventory of the Resources and Data Collection

The resources involved include:

Water resources: Quantity (stream size, volume and duration for which the supply is

available) and quality of water, the type of water resources i.e. bore/tube well; open dug

well, reservoir/pond/tank or river and location of the water resource.

Land resources: The size and shape of the area to be irrigated with the consent of WUAs

(Water User Associations), soil type for its texture and irrigation properties (field capacity,

wilting point, bulk density, allowable depletion level) including infiltration rate, and

topography of the land.

20

Climate: The climatic data required for the computation of crop water requirement.

Crop: Crop type, sowing/planting and harvesting period, crop coefficient, fertilizer

requirements, crop geometry. In general following guidelines can be used to ensure

adequate quantity of available water for supply of irrigation water to the wide spaced

(orchard) and close spaced (vegetable etc.) crops. However the area to be irrigated can be

decided on the basis of the water availability and the crop water demand.

2. Peak Crop Water Requirement:

The design of drip irrigation system needs the information on the peak water requirement,

however while the system is in operation, the water requirement during the specified

irrigation interval is required. Crop water requirement is calculated for each plant and the

water requirement of the whole area is estimated based on the water requirement per plant

and total number of plants.

3. Layout of the Drip Irrigation System:

It is possible to apply water to the whole field by drip irrigation method at the same time.

However this may result in the requirement of high discharge which may not be available,

further large diameter of mains and sub main which could make the system more

expensive and the high capacities of the fertigation and filtration units. Hence the whole

field needs to be divided in to the convenient number of subunits. Each subunit is then

designed separately and operated separately by having valve at the head of the subunit.

The layout of the micro irrigation system i.e. arrangement of main, sub mains and laterals

is done considering the shape, size and slope of the field. As for as possible, the sub main

should run along the slope of the field and lateral should be laid across the slope or along

the contour lines of the field.

4. Selection of Emitters:

The emitters are to be selected for its discharge, operating pressure, online/inline, pressure

compensating/non pressure compensating, point source/line source, single exit/multi exit

21

and surface/subsurface. The selection of particular type of emitter depends on the soil,

crop, topography, desired emission uniformity, available discharge and electricity/other

sources for operation of the system, water quality, water use efficiency and the cost.

5. Hydraulic Design of Pipe Network:

The pipe network in drip irrigation system consists of laterals, sub main and main. Water

under pressure flows through these pipes and as a result the pressure in the pipes reduces

creating the variation in pressure or pressure difference between any two points. The

emitter discharge depends on the operating pressure available in the pipe at emitter

connection and reduces with reducing pressure. Therefore there is variation in discharge

obtained by the emitters in system; affecting the emission uniformity.

The procedure of hydraulic design consists of:

1. Know the operating pressure of emitters

2. Find out the allowable head loss in lateral and sub main

3. Find out the lateral and sub main discharge

4. Find out the diameter and length of the lateral such that the head loss in the lateral is

within allowable limits for the given layout. For this purpose find out the head loss by

Hazen William or Darcy-Wesibach formula for different combinations of diameter and

length and select the suitable combination by trial and error method

5. Repeat the procedure for the sub main

6. Find out the diameter of main so that the velocity is within the allowable limit or find

out the head loss in main for the specified diameter of the main. The length of the main is

the distance of the field from the water source.

4.4 ESTIMATION OF WATER AND POWER REQUIREMENT FOR

INSTALLATION OF MICRO IRRIGATION SYSTEM

A. Estimation of Quantity of Water

To irrigate an area by drip / sprinkler irrigation system sufficient amount of water

should be made available at the place where the system needs to be installed. To

estimate the minimum quantity of water for meeting the irrigation water requirement

22

of any area, the following steps are required.

Collection of General Information

Information on type of water source, crops to be grown, topographic conditions,

type and texture of soil and climatological data are essential for designing the drip /

sprinkle irrigation system.

Layout of the Field

The design layout of the field / plot by giving appropriate specifications of the

lengths of main line, sub main line, lateral lines, distance of water source from

Pump station in meters to connect water source with the existing/planned crop in the

area must be worked out., discharge of the emitting device used (lph/ lps), Number

of Control Valves used as per the design layout of the proposed field/plot with

area(ha).

Crop Water Requirement

Water requirement of crops (WR) is a function of plants, surface area covered by

plants, evapo-transpiration rate. Irrigation water requirement has to be calculated

for each plant and thereafter for the whole plot based on plant population, for

different seasons. The maximum discharge required during any one of the three

seasons is adopted for system design. The daily water requirement for fully grown

plants can be calculated as under:

V= Ep x Kc x Kp x Wp x Sp

The total water requirement of the farm plot would be VxNo. of plants per sq mxA

Where:

V is the Water requirement (lpd plant)

Ep is the pan evaporation (mm/day) (Refer annexure XII for Ep values)

Kc is the Crop factor (Refer annexure XIII for Kc values)

23

Kp is the pan factor (For the Class A evaporation pan, the average K pan varies

between 0.7 and 0.8)

Wp is the wetted area (0.3for wide spaced crops and 0.9 for close spaced crops)

Sp is the spacing of crops/plant (m2)

B. Estimation of Horse power (HP) of Pumping Unit

Power required to pump the required irrigation water from the source and to develop sufficient

pressure to operate the drippers effectively.

The ideal drip irrigation system is one in which all drippers / emitters (or orifices) deliver

equal / uniform volume of water in a given irrigation time. The dripper / emitter flow variation

caused by water pressure can be controlled by hydraulic design.

Flow carried by each lateral line (de) = dripper discharge x No. of drippers per plant x No.

of plants along each lateral.

Flow carried by each sub-main line (ds) = de x No. of lateral line per sub main line Flow

carried by each mainline (dm) = ds x No. of sub-mains

The friction head loss in mains can be estimated by Hazen-Williams formula given below:

hf = 10.68x(Q/C)1.852

xD-4.87

x (L+Le), where hf is friction head loss in pipe(m)

Q = Discharge (m3/sec)

C = Hazen-William constant (140 for PVC pipe)

D = Inner dia of pipe (m)

L = Length of pipe (m)

Le = Equivalent length of pipe and accessories (See Table C, Annexure XIV)

Alternatively, friction head loss may be directly read from tables in Annexure XIV.

The design of lateral pipe involves selection of pipe for a given length, which can deliver required

quantity of water to the plant.

In designing the lateral, the discharge and operating pressure at drippers are required to be known

and accordingly, the allowable head can be determined by the same formula as the mainline.

24

Design Criteria

1. It should be ensured that the head loss in the lateral length between the first and last

emitter is within 10 percent of the head available at the first emitter.

2. The friction head loss in the mainline should not exceed 1 m / 100 m length of the

mainline. Friction head loss for various discharges is given in Table B (Annexure XIV) and

equivalent lengths of straight pipe in (m) giving equivalent resistance to flow in pipe fittings in

Table C (Annexure XIV).

After finalization of dimensions of main, sub-mains and laterals the selection of pump consists

of the following steps.

Total pressure head drop in meters due to friction (hf) = Friction head loss of main + Friction

head loss of sub-mains + friction head loss of laterals.

Operating pressure head required at the dripper = he in meters.

Total Static Head = hs in meters

Total Pumping Head (H) = hf +he +hs

Discharge of main = litres / sec

Efficiency (overall) = (60% in the case of electric pump,

40% in the case of diesel engine)

Horse power (HP) = (H x d) / (75 x e)

25

4.5 DESIGN EXAMPLE OF DRIP IRRIGATION SYSTEM

To install drip irrigation system for a new citrus plantation on one ha plots.

Basic Data Analysis

1. No. of Plants

Area (1 ha approx.) = 104 m x 96 m

Spacing (m) = 6 m x6 m

No of plants along the width of the field = 96/6 = 16 nos

No. of plats along the length of the field = 104/6 = 17 nos

Total no of plants = 16x17 = 272 nos

2. Estimation of Water Requirement

Kc = 0.9

Kp = 0.78

Wp = 0.3

Sp = 36

The irrigation water requirement is determined using Indian Meteorological Department

(IMD) pan evaporation data. The average monthly pan evaporation data for the area is given

below:

Normal Monthly Pan Evaporation Data

Month mm Month mm

January 099.2 July 145.6

February 119.6 August 134.6

March 176.3 September 134.6

April 210.2 October 144.6

May 245.4 November 112.2

June 198.8 December 94.4

26

From the above data the season wise total pan evaporation as well average pan evaporation is

given below:

The daily water requirement of plants is given below:

SN Season Evaporation

Water

Requirement

lpd / plant m3 / day /

ha

1 Kharif 4.8 4.8 x 0.9 x 0.78 x 0.3 x 36 = 36.3 10

2 Rabi 3.65 3.65 x0.9 x 0.78 x 0.3 x 36 = 27.6 7.6

3 Summer 6.83 6.83 x0.9 x 0.78 x 0.3 x 36 = 51.7 14.3

Therefore, the drip irrigation system has to be designed for the maximum requirement of

51.7 litre / day / plant during the summer season. For this the water requirement works out to 14.3

m3 / day / ha of plantation. If the average working hour of pump set is taken as 4 hours per day,

the discharge required would be as below :

Pumping rate = 51.7 / 4 = 13 litres / hr / plant

Pumping rate per ha = 14.3 m3 / day / ha

= 3.6 m3 / hr / ha

= 0.97 lps or 1 lps

Alternatively, a tank of 14.3 m3 capacity can be provided so that uninterrupted irrigation

may continue for 4 hours even in areas where power shut - offs are frequent.

3. Selection of Drippers

Number of Drippers:

Depending upon the type of dripper and discharge required their number can be estimated.

For a pressure head of 10 m and discharge at 4 litres / hour the number of drippers required are:

No. of drippers / plant = Rate of pumping / hour / plant

Avg. discharge of one dripper

= 13 / 4 or 3.25 say 3

It is assumed that the filed / plot is having an approximate area of 1 ha being 104 m long and

96 m wide. As such the mainline would be 104 m long and laterals would be 96 m in length. Plant

spacing of 6 m x 6 m, would require a total of 17 lateral lines. Each lateral would serve

approximately 16 plants and there would be 3 drippers / emitters per plant. Thus, the total number

of drippers / emitters per lateral would be 16 x 3 = 48 nos.

28

4. Main Line and Laterals

Main Line

The main line is designed to carry the maximum discharge required for total number of plants in

the farm field / plot.

Maximum discharge required = No. of plants x peak discharge per plant

= 272 x 13

= 3536 lph or 1 lps

Friction head loss in pipes (m)

Total length of main line = 104.0 m

Equivalent length of 17 straight = 8.5 m

Connection

Equivalent length of tee bends, etc = 6.0 m

TOTAL = 118.5 or say 120 m

From Table B it would be seen that for discharge of 1 lps through a pipe of say 40 mm diameter,

the friction loss would be 2 m per 100 m length of 2.3 m for 120 m equivalent length.

As the proposed system uses multiple openings, the friction loss is taken as 1 / 3 of the total

friction loss i.e. 2.3 / 3 i.e. 0.77 m. Thus the loss in mains is within 1.0 m / 100 m and a pipe of 40

mm diameter will be ideal in the layout.

Laterals

A lateral is so selected that the pressure difference from the proximate end to the last

dripper does not exceed 10 per cent of the normal operating head which in the present case is 10 x

10 / 100 = 1.0 for lateral of 100 m length. The land slope is 0.5 m / 100 m. Thus the total friction

loss allowable is 1 + 0.5 = 1.5 m.

In addition to 100 m length of laterals there is additional loss due to connectors. This is

29

generally taken as 0.1 to 1 m (on an average 0.5) of the equivalent length of a dripper. The

equivalent length of 48 drippers would this be 16 x 0.5 = 8 m. Thus, total equivalent length for

calculation of friction loss in laterals would be 8 m. The total flow in each lateral is 192 lph. i.e. 4

x 3 x 16. A perusal of Table A shows that for 200 lph flow the friction loss in 13.9 mm inner

diameter pipe would be 1.7 m per 100 m length. Therefore, in 104 m length it would be 1.77 m.

It is a general practice that friction losses are taken at 1 / 3 of the total equivalent length of pipes

with multiple dripper / connections. Thus the friction loss works out to 1 / 3 x 1.77 = 0.59 m which

is within the maximum permissible limit of 1.0 m. Therefore, 14 mm (OD) lateral pipe of 96 m

length is suggested in this scheme.

5. Horsepower of Pumpset

The HP of pumpset required is based upon design discharge and total operating head. The

total head is the sum of total static head and friction losses in the system.

Static Head

i) The total static head is the sum total of the following :

a. Depth to water 15 m

b. Drawdown 3 m

c. Outlet level above ground level 1 m

d. Friction loss in pipes, bends, 2 m

foot valves etc.

Total 21 m

ii) The friction loss in the drip unit is as under :

a Friction loss in main pipe 0.77 (m)

b Friction loss in laterals 0.59

(m)

c Minimum head required over drippers 10.00

(m)

11.36 (m)

Total Head = Static Head + Friction Head Loss

30

= 21.00 + 11.36

= 32.36 or say 33 m

HP of pump set = (Q x H) / (75 x e)

Where Q = Discharge (lps)

H = Head (m)

e = Pumping Efficiency (0.7)

HP = (1 x 33) / (75 x 0.70)

= 0.63 or say 1 HP

CHAPTER 5

SPRINKLER IRRIGATION SYSTEM

In sprinkler irrigation, water under pressure is discharged in the air which falls back to

earth‘s surface as artificial rainfall. A set of nozzles are used to discharge under pressure. Nozzles

are attached to a network of High Density Polyethylene (HDPE) pipes for simulating the rainfall.

Pumps are used to discharge water under pressure. This type of irrigation is best switch for sandy

soils, undulated and hilly terrain. Sprinkler Irrigation can be used in following crops - Wheat,

Cotton, Groundnut, Tabaco, Potato, Onion, Ginger, Peas, etc.

In addition to above, sprinkler irrigation can also be used for irrigation leafy vegetables,

nurseries, hardening of seeds, landscaping, etc.

Types of sprinkler irrigation system

Micro-sprinklers

Micro-sprinklers are emitters, commonly, known as sprinkler or spray heads. They operate by

spreading water through air, usually, in predetermined patterns. Depending on the water throw

patterns, micro-sprinklers are referred to as ‗mini-sprays‘, ‗micro-sprays‘, ‗jets‘ or ‗spinners‘. The

sprinkler heads are external emitters individually connected to lateral pipes, typically, using what

can be called ‗micro-tubes‘ or a small diameter tubing. The sprinkler heads can be mounted on a

support stake of 50-150 cm height, connected to the supply pipe. Micro - sprinkler system

requires less energy, and generally, operates at a pressure range of 1–3 kg/cm2 and a discharge

range of 40–75 lph. Micro-sprinklers are desirable because fewer sprinkler heads are required to

cover a large area. The system is suited for crops with shallow rooting pattern like garlic, onion,

etc.

Centre pivot

The centre pivot is capable of irrigating most field crops. It consists of a single sprinkler lateral

supported by a series of towers. It is anchored at one end and rotates around a fixed central point

called ‗pivot point‘. The control panel attached to the pivot point gives commands to the central

pivot machine. A drive unit or drive tower touches the ground, which contains necessary

33

components for the machine to move. It consists of a base beam, drive train, wheels and other

structural support equipment. The towers are self-propelled so that the lateral rotates around the

pivot point installed in the center of the irrigated area. The long pipes between the drive units are

called ‗spans‘.

Centre Pivot

Towable pivot

Towable pivot is similar to centre pivot. But here, the pivot is towed away by a tractor. There are

3–4 wheels in the centre of the pivot, which make it possible to move the pivot from one place to

another by pulling it with the help of the tractor. It helps farmers to carry out mechanised

irrigation in an economical manner. It can easily irrigate fields as the machine can be towed away

from one field to another in minimum time.

Towable pivot

34

Rain gun

A rain gun is used as a water spray mist or fog beam. It discharges water at less than 175 lph. It is

used to irrigate trees and other crops separated widely. Fruit tree crops like citric fruits, mango,

guava, avocado, etc., can be irrigated with a rain gun. The passage diameter of the rain gun is

small. Therefore, the release of filtered water is essential. The minimum operating pressure is 1.5–

2 kg/cm2. Rain gun is suitable for field crops like groundnut, onion, potato, sugarcane, cotton and

plantation crops, such as coffee and tea.

Impact sprinkler

This sprinkler is driven in a circular motion by the force of outgoing water, and at least, one of its

arms extends from the head. The sprinkler arm is repeatedly pushed back into the water stream by

a spring. When the arm strikes the water stream, it scatters the stream and re-orients the flow,

enabling a uniform watering area around the sprinkler. Impact sprinkler is recommended for

closely spaced field crops like potato, leafy vegetables, cotton, oilseeds, pulses, cereals, fodder

crops, etc.

Rain Gun Impact Sprinkler

35

Pop up sprinkler

A pop up sprinkler consists of an inlet, body, cap, wiper seal, riser, nozzle and radius adjustment

screw. Such a sprinkler is portable and easy to install, thereby, making it ideal for irrigating

lawns, seasonal flowers and planting beds.

Linear move sprinkler

Linear move sprinkler irrigation system is similar to the centre pivot system in construction,

except that neither end of the lateral pipeline is fixed. It is composed of a series of towers that are

suspended and move laterally in the direction of rows. The whole line moves down the field

perpendicular to the lateral. Water delivery to the continuously moving lateral is by a flexible

hose or open ditch pickup. Both the centre pivot and linear move systems are capable of high

efficiency water application.

5.1 BENEFITS OF SPRINKLER IRRIGATION METHOD

15-20% of total water which is lost in conveyance in surface irrigation is saved in sprinkler

Irrigation.

In canal Irrigation, conveyance losses amount to as high as 30-50% in sprinkler irrigation. In

other words there is 25-50% savings in water consumption.

Sprinkler irrigation prevent water logging in the field due to which there is absence of water run-

off.

Sprinkler irrigation is a boon in places where surface irrigation is not feasible due to undulations

in land under cultivation & hilly terrain.

Sprinkler irrigation is very suitable for lands with high slope and sandy soils.

With Sprinkler irrigation, optimum level of moisture can be maintain in soil which leads to

increase is quantity and quality of agricultural production.

Water soluble insecticide, herbicides and pesticides can be easily applied during irrigation with

sprinklers.

Sprinkler irrigation, manifestation of various crop diseases can be substantially reduced which

leads to savings for farness.

37

5.2 COMPONENTS OF SPRINKLER IRRIGATION METHOD

Pump unit and valves

A pump is used for developing the required pressure. It can be used under the following

conditions.

• The land is undulating for leveling (the leveling work will be cost-intensive).

• The soil is porous, erodible and impermeable (which makes it difficult to irrigate it by any

other method).

• The flow rate is too less for employing surface irrigation method.

Filtration unit

Filtration unit is required to remove the impurities present in the irrigation water. Hydro-

cyclone, media and screen are the different types of filter. The choice of filter depends on the

quality of water. If the quality of water is poor, then a filter of higher mesh size is used.

Pipeline

The layout of mains, sub-mains and laterals depends on local conditions like topography, soil

characteristics and source of water. The main line must be laid along the slope and the laterals

across the slope or nearly on the contours. In portable system, the laterals need to be of the same

size so that they can be changed easily.

Sprinklers

The selection of sprinkler depends on its nozzle size and the pressure with which it discharges

water. It must also be ensured that the water discharged does not cause run-off or damage to the

crops. Besides, it must supply water to the crops sown in a field uniformly under the prevailing

wind conditions. It must meet the irrigation water requirement of a crop and the irrigation

frequency.

38

39

5.3 PLANNING AND DESIGN OF SPRINKLER IRRIGATION SYSTEM

A sprinkler irrigation system needs to be laid and designed properly to suit the conditions

of a particular site to achieve high efficiencies. The choice of sprinkler system depends on i) land

topography that cannot be properly leveled owing to the subsoil being exposed and cost involved

in land leveling ii) soil texture, particularly infiltration rate of the soil so that the application or

precipitation rate of the system is less than the infiltration rate of the soil iii) available water

resources and eventually matching the capacity of sprinkler system with the water requirement of

the crops and, the system with high water application efficiency, and iv) cost effective from the

point of crop production economics.

1. Inventory of the Land and Water Resources

The inventory of resources includes following:

i) Topographical map of the Area:

The topographical map of the field needs to be prepared. The map should include the field

boundaries and the locations of the bunds with the consent of WUAs or landholder, farm roads

building and location of water resources. The map should also include the contour map of the

area. The contour map enables to determine the slope of the field, if any, in both the direction.

The slope is required to decide the layout and placement of the pipe network (main, sub main

and laterals) and computation of the elevation difference which is required for the design of

pipes in terms of its diameter and length.

ii) Water Resources:

The information on quantity and quality of available water resources is required for design of

sprinkler system. The quantity of the water resources in terms of the seasonal availability of the

water; and discharge available for irrigating the field and duration for which it is available per

day are required to match with the crop water requirement.

40

iii) Crops to be Irrigated:

The information on crops, its root zone depth, crop coefficient, and allowable depletion level is

required for computing the water requirement of the crops and irrigation frequency. The

climatic and soil parameters are required to determine crop water requirement.

iv) Soils:

The soil parameters such as field capacity, wilting point, bulk density and infiltration rate are

used for irrigation system design. Field capacity, wilting point, bulk density are required for

estimating the available soil water in the root zone The information on infiltration rate is used in

selecting the nozzle size, type of nozzle and lateral spacing.

v) Climate:

The weather parameters such as pan evaporation, rainfall, temperature, relative humidity, wind

speed and sunshine hours are required to compute the water requirement of the crops. The peak

water requirement estimation requires peak summer weather parameters such as solar radiation,

temperature, humidity etc.

vi) Availability of Power Source:

The type of source of power can be electricity or diesel or both. Irrigation system can be

planned and designed based on the assured timings of availability of power supply.

2. Hydraulic Design of Pipe Network

The pipe network in the sprinkler irrigation system consists of the lateral, sub main and

main pipeline. The sprinkle nozzles are mounted on the laterals; laterals are connected to the sub

main and sub main to the main. Main pipe line takes water from the source through the pump. It is

desired to design the pipe network appropriately for uniform water application and economical

system cost. As the sprinkler system requires pressure to operate, both uniformity water

application and system economy are affected by the frictional head loss through the pipes. Large

variation in friction head loss in the lateral or sub main reduces the uniformity in water application

on the other hand too small variation results in high uniformity, which requires larger pipe size

41

makes system more expensive. Hence it requires optimal combination of hydraulic and economic

consideration. Hazen-Williams equation is commonly adopted for estimating frictional head loss

through sprinkler pipes.

Flow Velocity in Pipe

Normally flow velocities in pipes should not exceed 3m s-1 .For permanent systems with

polyvinyl chloride (PVC) plastic pipe, and asbestos cement (AC) pipe used for water supply,

water flow velocity should not exceed 2.25 m s-1 and most manufactures caution against using

water flow velocity in excess of 1.6 ms-1.

Allowable Head Loss in Sprinkler Pipe

Pressure loss occurs due to friction and joints. This should not exceed practical value. Normally

it should be between 15 and 20 per cent of the total head. The recommended practice to design

the sprinkler lateral is not to exceed the pressure variation more than 20% of the higher

pressure. The difference in elevation head is considered while determining the variation in

pressure. This may be paying of laterals in upward slope or down slope. While the lateral is laid

on up slope direction, the less pressure is available at the nozzle while lateral laid on down slope

direction, the additional pressure is available at the sprinkler nozzle due to gain in energy.

Pipe with Multi Outlet

When there are no outlets along the length of the lateral or sub main (usually called as closed

pipe line or blind pipe), the head loss due to friction can be computed by Hazen-William

formula However, in sprinkler lateral or sub main, outlets along the length of the pipe are given

as sprinkler heads or sprinkler laterals as the case may be. Flow of water through the closed or

blind pipe of a given diameter causes more frictional head loss compared to that of a pipe with

number of outlets along the length of the pipe which is due to the fact that the flow rate

decreases with every passing outlet. To accurately compute friction loss in the lateral with multi

outlet, start at the last outlet on the pipe line and work back to the head of the pipeline,

computing the friction head loss between each outlet for the flow rate between two outlets. In

case of multiple outlets the frictional head loss through the blind pipe is computed for the given

flow rate and then multiply with reduction factor (F) due to reducing flow rate. The reduction

factor depends on the number of equally spaced outlets on the lateral.

42

Pumps and Power Units

The suitable size of pump is selected considering the maximum total head against which the

pump expected to operate and deliver the required discharge. This is be determined by:

Ht = Hn + Hm ± Hj + Hs

where,

Ht = total design head against which the pump is working, m

Hn = maximum head required at the main to operate the sprinklers on the lateral at the required

average pressure, including the riser height, m

Hm = maximum friction loss in the main and in the suction line, m

Hj = elevation difference between the pump and the junction of the lateral and the main, m, and

Hs = elevation difference between the pump and the source of water after drawdown, m

5.4 ESTIMATION OF WATER AND POWER REQUIREMENT FOR

INSTALLATION OF SPRINKLER IRRIGATION SYSTEM

A. Estimation of Quantity of Water

To irrigate an area by drip / sprinkler irrigation system sufficient amount of water

should be made available at the place where the system needs to be installed. To

estimate the minimum quantity of water for meeting the irrigation water requirement

of any area, the following steps are required.

Collection of General Information

Information on type of water source, crops to be grown, topographic conditions,

type and texture of soil and climatological data are essential for designing the drip /

sprinkle irrigation system.

43

Layout of the Field

The design layout of the field / plot by giving appropriate specifications of the

lengths of main line, sub main line, lateral lines, distance of water source from

Pump station in meters to connect water source with the existing/planned crop in the

area must be worked out., discharge of the emitting device used (lph/ lps), Number

of Control Valves used as per the design layout of the proposed field/plot with

area(ha).

Crop Water Requirement

The water application requirement for fully grown plants can be calculated as

under:

V= Ep x Kc x Kp

Where:

V is the Peak evaporation rate (mm/day)

Ep is the pan evaporation (mm/day) (Refer annexure XII for Ep values)

Kc is the Crop factor (Refer annexure XIII for Kc values)

Kp is the pan factor (For the Class A evaporation pan, the average K pan varies

between 0.7 and 0.8)

Discharge requirement = Area of the plot x Peak Evaporation Rate

Discharge of nozzles depends on radius of area required & selection of nozzles.

B. Estimation of Horse power (HP) of Pumping Unit

Power is required to pump the required irrigation water from the source and to develop sufficient pressure

to operate the nozzles effectively.

The ideal sprinkler irrigation system is one in which all nozzles deliver equal / uniform volume of

water in a given irrigation time. The nozzle flow variation caused by water pressure can be

44

controlled by hydraulic design.

Flow carried by each lateral line (de) = Nozzle discharge x No. of nozzles in each lateral.

Flow carried by each sub-main line (ds) = No. of lateral line per sub main line x de

Flow carried by each mainline (dm) = ds x No. of sub-mains

The friction head loss in mains can be estimated by Hazen-Williams formula given below:

hf = 10.68x(Q/C)1.852

xD-4.87

x (L+Le), where hf is friction head loss in pipe(m)

Q = Discharge (m3/sec)

C = Hazen-William constant (140 for PVC pipe)

D = Inner dia of pipe (m)

L = Length of pipe (m)

Le = Equivalent length of pipe and accessories (See Table C, Annexure XIV)

Alternatively, friction head loss may be directly read from tables in Annexure XIV.

Design Criteria

1. It should be ensured that the head loss in the lateral length between the first and last

emitter is within 10 percent of the head available at the first emitter.

2. The friction head loss in the mainline should not exceed 1 m / 100 m length of the

mainline. Friction head loss for various discharges is given in Table B (Annexure

XIV) and equivalent lengths of straight pipe in (m) giving equivalent resistance to

flow in pipe fittings in Table C (Annexure XIV).

After finalization of dimensions of main, sub-mains and laterals the selection of pump consists of the

following steps.

Total pressure head drop in meters due to friction (hf) = Friction head loss of main + Friction head loss

of sub-mains + friction head loss of laterals.

Operating pressure head required at the dripper = he in meters.

45

Total Static Head = hs in meters

Total Pumping Head (H) = hf +he +hs

Discharge of main = litres / sec

Efficiency (overall) = (60% in the case of electric pump,

40% in the case of diesel engine)

HP of pump set = (Q x H) / (75 x e)

MAINTENANCE AND PRECAUTIONS

Drip Irrigation System

There are no moving parts in drip irrigation so if the system is used properly, it only requires

maintenance of pump, and the following points should be kept in mind for the operation and

maintenance of drip irrigation system:

1- The place where the system is installed, there should be a restriction on the movement of animals

otherwise the system may be damaged.

2- Normally the system is run for half an hour or an hour per day. In case of extreme change in

weather, operational changes become necessary.

3- In order to make the drip irrigation unit more useful, it is necessary that along with the

installation of the system, suitable crop combination shall be considered like pomegranates

plants can be planted with the garden of sweet lime. Sweet lime plants will give fruits in four

years and pomegranate plants will start giving fruits in 1.5 years.

4- In the use of drip irrigation, the main problem is that the pipes and drippers can get clogged, for

this it is necessary to have an effective filteration along with backwashing facility.

Sprinkler Irrigation System

Following precautions shall be taken during sprinkler irrigation:-

a) All equipment and fittings shall be properly inspected before and after use.

b) Clean water devoid of sand shall be used for sprinkler irrigation.

c) After use of insecticides or pesticides all equipment shall be thoroughly washed with clean

water.

d) Washers, rubber seals and other fittings shall be inspected on regular basis and if needed shall be

replaced at the earliest.

LIMITATIONS

Drip Irrigation System

High Initial cost.

Clogging of Emitters.

Technical Knowledge is required for design, installation & maintenance.

Sprinkler Irrigation System

Water distribution from sprinklers is non-uniform when speed of winds is high in the area.

Ripe fruits are affected adversely by sprinkler irrigation.

Regular source of water is necessary for effectiveness of this technique.

Water should be free from sand, floating materials and shall not be saline.

Energy requirements for this technique are very high.

This technique is not suitable for clayey soils and in dry areas.

Grooves and furrows are not required in sprinkler irrigation. This leads to saving of land

which can be utilised for increasing crop area.

Farmers need to be made aware and educated regarding sprinkler irrigation.

This technique depends on type of crop under cultivation.

In this technique, multiple types of components are used leading to high maintenance cost.

49

Chapter 8

TRAINING FOR SYSTEM OPERATION

Human resource development is an important component of any new scheme. Under the

programme training of farmers, WUA or land holders and entrepreneur etc , micro irrigation

technician and farm pond lining technician and trainers‘ training may be taken up.

Operation and Maintenance of the system requires adequate training of users for system

operation etc. The manufacturers should provide detailed operational and maintenance manual in

the local vernacular language at the time of installation of the system.

Service centres and / or offices of drip / sprinkler system manufacturers /authorised distributors

may be hired to provide technical guidance on system maintenance schedules, supply spare parts

and ensure satisfactory performance of the system during the warranty period.

Chapter 9

QUALITY CONTROL

Crucial aspect of supply of micro irrigation systems is the quality of hardware which is used by

the farmer. It needs to been ensured that quality components having BIS marking (wherever

applicable) are installed in the field. Poor quality has an adverse impact on performance of the

system which may affect yield of the crop, quantity of water applied, quantity of fertilizer

delivered to the plant etc. It may also increase energy consumption. In fact, sub-standard system

will not only adversely impact performance, but could also reduce the durability and the life of

the components and/or system.

The quantity of material required for conducting the test is as detailed below:
