7. DISINFECTION OF PIPELINES

• GENERAL

All pipes, fittings, valves and appearances shall be disinfected according to the specification of Miyahuna listed below.

• DISINFECTION OF PIPELINES

After the completed pipeline is tested, approved and backfilled, disinfections shall be performed in the following manner: after flushing the pipes, the system shall be drained completely, all valves shall be closed carefully and the system filled with a chlorine solution.

All pipes, fittings, valves and appurtenances shall be disinfected by the Contractor as specified herein unless otherwise directed by the Engineer’s Representative. The Contractor is also responsible for conducting bacteriological test for all pipe laying through a laboratory. The cost of disinfection and the bacteriological test shall be borne by the Contractor.

The contractor should use potable water to execute the bacteriological test, and has three options to fulfil the specs:

• Using Miyahuna water direct from the network by installing a bypass connection and as instructed by the concerned people in Miyahuna. The costs for the mentioned connection as well as required material, labour, etc. will be borne by the contractor.

• Using Miyahuna tankers

• By using private tankers the water should be tested first by Miyahuna to ensure that the delivered water is potable water before executing any bacteriological tests. The costs to ensure the water quality will be borne by the contractor.

The attention of the Contractor is directed to the requirements of the Contract whereby he is responsible for preventing the entry of foreign material of any kind from entering the pipe. The Contractor shall take extreme care to keep the interior of the pipelines free of dirt and other foreign material. If in the opinion of the Engineer’s or the Employer, dirt or other foreign material entered a pipe which cannot be removed by flushing, then the Contractor shall clean and swab the interior of the pipe with a five percent hypo-chlorite disinfecting solution to the satisfaction of the Engineer’s Representative.

The Contractor shall, during the initial filling of the pipeline, concurrently introduce feed of chlorine at the same point where the pipeline is being filled. The rate of filling and the feed rate of the chlorine shall be proportioned so that the initial concentration of the chlorine in the water in the pipeline is between 50 and 100 milligrams per litre. To assure that this concentration is maintained, the chlorine residual shall be measured at blow-off, combination air valves, or other locations during the filling operation.

The following is the amount of chlorine required, if either liquid chlorine (gas at atmospheric pressure) or a one percent chlorine solution is used, to produce a 100 milligram per litre concentration in 100 meters of pipe for the various diameters of pipe to be disinfected under this Contract.

The use of liquid chlorine shall only be permitted when suitable equipment consisting of a solution feed chlorinator together with a booster pump of injecting the chlorine gas-water mixture into the pipeline to be disinfected is used. Introduction of chlorine gas directly from the supply cylinder shall not be allowed.

After completion of the disinfections operation for one pipeline section the Contractor may reuse this chlorinated water to disinfect adjacent sections of the pipeline by adding additional chlorine as required to produce the specified concentration of chlorine.

The Contractor shall submit a detailed description of the procedure he proposes to use to disinfect the pipeline including a description of all equipment to be used for the Engineer’s Representative approval prior to starting the disinfections operations.

Payment for all labour, material, and equipment, including the cost of all water and chlorine required to disinfect the pipeline and appurtenances shall be included in the costs for meter run of the pipe.

The chlorinated water shall remain in each section of the pipeline for at least 24 hours and during this period all valves and blow-off shall be operated in order to disinfect these appurtenances. At the end of the 24-hour period, the water in the pipeline shall contain no less then 25 milligrams chlorine per litre throughout the length of the pipeline. Shall the pipeline fail to have the specified chlorine concentration at the end of the 24-hour period, the Contractor shall repeat the operation as necessary to provide complete disinfections.

• FLUSHING OF THE PIPELINE

All pipelines shall be flushed by the Contractor after all hydrostatic pressure tests and disinfections operations have been performed and accepted by the Engineer’s Representative.

Water for flushing the pipes shall be provided by the contractor as indicated under section – Disinfection of Pipelines.

After draining the chlorine solution the pipe system shall be flushed with potable water until the free chlorine content is between 2 to 4 milligrams per litre.

17. PRESSU

RE TESTING

17.1 HYDROSTATIC PRESSURE TESTING OF DI PIPES

After completing the installation of a water main, or a section of the line, and before the joints are covered, a hydrostatic test of the line shall be made by the Contractor. A sufficient time for the curing of concrete thrust blocks must be allowed before the test is made. All backfilling and compaction over and around the pipes and thrust blocks must be completed except for the pipe joints to be left open for observation of any leaks, before the test is made. In accordance with EN 805, pipelines have to undergo an internal pressure test. The definitive criteria for performing this test on water pipelines are EN 805 and the DVGW’s worksheet W 400-2.

12 Test sections

If necessary, longer pipelines should be divided into sections. The test sections should be arranged so that the

• test pressure is reached at the lowest point of every test section;

• at the highest of point of each test section at least 1.1 times the level of the system test pressure

is reached;

• the amount of water required for the pressure test can be supplied and drained off; and

• the maximum length to be tested does not exceed 2.5 – 3 km.

13 The pipeline should be vented as well as possible with ‘pigs’ and filled from its lowest point with drinking water. Backfilling and interlocking

If necessary, pipes must be covered with filling material before the pressure test to avoid any changes in length. Backfilling the connections are optional. Pipelines that are not longitudinally force-locked must be anchored at their ends, bends, branches and reducers against the forces produced by the internal pressure. Assessment of the supports needed for this purpose should be done as per specifications.

There is no need for supports on longitudinally force-locked systems, provided that in each case the lengths to be restrained have been installed in compliance with the specifications.

Squeezing against a closed shut-off valve serves no purpose. The temperature on the outer wall of the pipe should be kept as steady as possible and must not exceed 20°C.

14 Filling of the Pipeline

For drinking water pipes, initial disinfection should be carried out along with the pressure test. This requires a concentration of at least 50 mg of chlorine per litre of water. Depending on how dirty the pipeline is, the level of chlorine can be increased to 150 mg per litre of water. The relationship of the volume of water added to the increase in pressure can give a clue to any leaks or insufficient venting. As the pressure increases, the rate of water consumption should therefore be noted bar by bar.

Where a line has been laid and is vented properly, the amount of water that needs to be pumped per bar of increased pressure is almost constant. Taking into account the compressibility of water and the elastic property of the pipe, it is (theoretically) c. 50 ml/m³ pipeline content/bar. In practice, this figure is around 1.5 to 2 times higher, as trapped air in the fittings and pipe and fitting connections has to be compressed.


107

107

The table indicates the amounts of water required in liters per 1 bar of increased pressure for pipeline lengths of 100 up to 1,000 m, assuming a 100% extra allowance for trapped air.

Performing a pressure test

The following procedure for carrying out a pressure test on ductile cast iron pipes is described in DVGW worksheet W 400-2:

▪ Standard method (for all DNs, with and without CM lining)

▪ Shortened method procedure (up to DN 600, with CM lining)

We describe below the two most frequently used methods: the standard method and the shortened procedure.

The level of test pressure in both procedures is as follows:


108

108

▪ For pipelines with allowable operating pressure of up to 10 bar:

1.5 x nominal pressure

▪ For pipelines with allowable operating pressure of over 10 bar: Nominal pressure + 5 bar.

The standard methodfor DI pipes

The standard method is carried out in three stages:

▪ Preliminary test

▪ Pressure loss test

▪ Main test

Preliminary Test

The purpose of the preliminary test is to saturate the Cement Mortar (CM) lining and to stretch the pipeline. To do this, the test pressure is kept constant for a period of 24 hours by permanently pumping in more air as and when required. If any leaks are found or any changes in length occur beyond what is allowed, then the pressure must be released from the pipeline and the cause remedied.

Pressure loss test

The purpose of the pressure loss test is to establish freedom of air movement in the pipeline. Air pockets in the pipeline can lead to incorrect measurements and/or cover up small leaks. A sufficient volume of water (ΔV) is drawn off from the line until a drop in pressure (Δp) of at least 0.5 bar materialises. The volume of water (ΔV) drawn off is then measured. The test pressure is subsequently restored. The pipeline is deemed to be adequately vented if ΔV is not greater than the allowable change in volume (ΔVzul ). If this is not the case, the line must be vented again. ΔVzul is calculated as follows: ΔVzul = 1.5 x a x Δp x L ΔVzul = allowable change in volume [cm³] Δp = measured drop in pressure [bar] L = length of the tested section [m] a = pressure constants that distinguish the type of pipe [cm³/(bar x m)]

➔ see following table

Main Test

Following the pressure loss test, the main test is then carried out. The duration of the test is as follows: Up to DN 400 3 h DN 500 up to DN 700 12 h over DN 700 24 h


109

109

The test criteria are deemed to have been met if at the end of the test the drop in pressure is not greater than specified below: Nominal Pressure Test P ressure Max. Pressure loss.

10 15 bar 0.1 bar 16 21 bar 0.15 bar over 16 PN + 5 bar 0.2 bar

Test Report A test report should be produced. Templates for test reports are included in DVGW worksheet W 400-2. These contain the necessary details such as:

▪ Description of the line

▪ Test details

▪ Description of the test procedure

▪ Findings during the test

▪ Check note

The shortened standard method for DI pipes

The advantage of the shortened standard method is largely one of enormous savings in time. The time required is approx. just 1.5 hours The shortened standard method is carried out in three stages:

▪ Saturation stage

▪ Pressure loss test

▪ Leak test

Saturation level In order to achieve a high level of saturation, the test pressure is kept constant for half an hour by permanently pumping water. The key factor for saturation is first and foremost the level of test pressure. Unduly low pressure cannot be compensated for by prolonging the saturation level. Pressure loss test The purpose of the pressure loss test is to establish freedom of air movement in the pipeline. Air pockets in the pipeline can lead to incorrect measurements and/or cover up small leaks. At test pressure, a volume of water (ΔV) is drawn off from the pipeline. The resultant drop in pressure (Δp) is measured. In the subsequent leak test this becomes the allowable pressure loss (Δpzul). Following the pressure loss test, the test pressure is restored. ΔVzul is calculated as follow: ΔVzul = (DN x L) / (100 x k) ΔVzul = allowable change in volume [cm³] L = length of the tested section [m] 100 x k = proportionality factor, k = 1 m/cm³ The pipeline is deemed to be adequately vented if when drawing off the volume of water ΔVzul, the drop in pressure is greater than or equal to the minimum levels specified for Δp specified in the table below.


110

110

Leak test

The pipeline is deemed to be air-tight if the fall in pressure (Δp) goes down at a constant rate over equal periods of time and over the duration of the leak test does not exceed the level ascertained (Δpzul) in the pressure loss test. The duration of the test is one hour.

Test Report A test report should be produced. Templates for test reports are included in DVGW worksheet W 400-2. These contain the necessary details such as:

▪ Description of the line

▪ Test details

▪ Description of the test procedure

▪ Findings during the test

▪ Check note

15 Stop Ends

A simple TEST END (Test facility) consists of a standard FG flanged-spigot pipe made of DI according to standard length for each diameter (about 0.5-1.0m long) onto which a threaded flange with a 2” (DN50) opening for accommodating ingoing water and out coming air. The TEST END may also include an opening through which the test water may be pumped from the line, if necessary. The test end shall be jointed to the pipe to be tested by means of a standard coupling (e.g. VJ Coupling) or two spare flanges. The Test End shall be secured with a temporary anchorage to hold it in place against the test pressure.


111

111

16 Air Removal before Test

Before applying the test pressure, all air shall be expelled from the pipe. After all the air has been expelled, all stop cocks shall be closed and the test pressure applied as specified above. The line shall be filled slowly to prevent possible water hammer.

17 Examination during Test

All exposed pipes, fittings, valves, hydrants and joints shall be carefully examined during the pressure test. All joints showing leaks shall be rejoined until tight, or the pipe material replaced. Any defective pipes or joints, fittings or valves discovered as a result of this pressure test shall be repaired or removed and replaced by the Contractor at his own expense with sound material and the test shall be repeated until proved satisfactory to the Engineer’s Representative.

18 Cost of Testing

The Contractor shall provide a sufficient quantity of gauges, pumps, stop ends, and connections and all things necessary and suitable for the testing of all pipes as described herein. The Contractor shall also provide all necessary temporary works in connection with test, and shall remove the same on successful completion of the test. All tests shall be done in the presence of the Engineer’s Representative (Resident Engineer) and the results of such tests shall be elaborated in a test report and signed by the Contractor and Resident Engineer and handed over to the Resident Engineer. Payment according to schedule for pipe laying is based on such reports. All equipment, labour, materials, and water necessary for the carrying out of these tests to the complete satisfaction of the Engineer shall be provided by the Contractor at his own expense. Shall any test fail, the Contractor shall, after repairing and making good any leaks, carry out further tests all as described above until such test meets the requirements contained herein. All such tests and retests shall be at the expense of the Contractor.

17.2 PRESSURE TEST OF HDPE PIPES

19 Pressure inspection in accordance with the contraction method

The test procedure shall be carried out according to EN805:2000 in up to three steps:

▪ preliminary test;

▪ pressure drop test;

▪ main pressure test;

Preliminary test HDPE Pipes

The pipeline shall be divided into practicable test sections, completely filled with water and vented. After that the pressure shall be raised continuously and quickly (in less than 10 minutes) to the system test pressure (STP) at the lowest point shell be fixed at 16 bars. Maintain STP for a period of 30 minutes by pumping continuously or at short intervals. During this time carry out an inspection to identify any obvious leaks. Allow a further period of 1 h without pumping during which the pipeline may stretch by visco-elastic creep. Measure the remaining pressure at the end of this period. If the pressure has decreased by more than 30%, interrupt the preliminary phase and depressurize the test section. Check the test conditions e.g. influence of temperature, indication of leakage, and rectify the defaults. Only resume the test procedure after a relaxation period of at least 60 minutes.


112

112

Pressure drop test HDPE Pipes

Reduce rapidly the remaining actual pressure measured at the end of the preliminary phase by discharging water from the system to produce a ∆p of 10-15% of STP. Measure precisely the removed volume ∆V. Calculate the allowable water loss ∆Vmax using the following formula and check that the removed volume ∆V does not exceed ∆Vmax. ∆Vmax = 1,2 x V x ∆p x (1/EW + D/e x ER) Where ∆Vmax is the allowable water loss in litres; V is the volume of the tested pipeline section in litres; ∆p is the measured pressure loss in kilopascals; EW is the bulk modulus of water in kilopascals; D is the internal pipe diameter in metres; e is the wall thickness of the pipe in metres; ER is the modulus of elasticity of the pipe wall in the circumferential direction in

kilopascals; 1,2 is an allowance factor (e.g. for air content) during the main test phase; For the interpretation of the result it is important to use the exact value of ER considering the temperature and the duration of the test. Especially for smaller diameters and shorter test sections ∆p and ∆V should be measured as accurately as possible. If ∆V is more than ∆Vmax interrupt the test procedure and vent again after the pipeline has been depressurized.

Main test HDPE Pipes

The visco-elastic creep due to the stress caused by STP is interrupted by the integrated pressure drop test. The rapid decrease of the pressure leads to a contraction of the pipeline. Observe for a period of 30 min (main test phase) the increase of pressure resulting from the contraction. The main test phase is considered to be successful if the pressure curve shows an increasing tendency and does not decrease at any time of this 30 min period. If during that period the pressure curve shows a falling tendency, it indicates a leak within the system. In case of doubt extend the main test phase to 90 min. In that case the pressure loss is limited to 25 kPa from the maximum value occurring within the contraction phase. If the pressure drops by more than 25 kPa the test fails. Rectify any defect in the installation revealed by the test and repeat the test. The repetition of the main test phase may only be done by carrying out the whole procedure including the relaxation period of 60 min in the preliminary phase.

7 ISOLATION WORKS AND TETING :

One of the main steps of implementing NRW reduction practices in Zarqa

Governorate is to isolate BA-8 DMAs. The process of isolation will start after installing a

dedicated main feeder for each DMA to ensure the adequate water supply. Each DMA

will be metered with an electromagnetic bulk water flow meter installed at the entrance

of that DMA measuring the amount of water that is supplied to that specific district. The

isolation process for DMAs will reduce NRW significantly since Isolation activities may

reveal leaks and/or connections to redundant mains, which will be corrected during this

process.

Isolation process includes; conducting Wet/Dry test and/or conducting pressure tests it

may require installing boundary meters and/or valves and/or installing new pipes or end

caps.

All DMAs could be considered hydraulically isolated by comparing flow data and

pressure changes of boundary valve operations. In case of not having an isolated DMA,

it is required to repeat the pressure test by installing pressure loggers across boundary

valves to identify variances or to carry out wet/dry test again.

To examine isolation, Wet/Dry test will be carried out for both inside and outside the

boundary of a DMA. A survey will take place around the boundary of the DMA to check

16 | P a g e

the status of water supply and produce isolation inspection report. In case of having an

isolated DMA other NRW reduction activities will take place accordingly. However, if

the isolation test failed more investigation will take place, including the employment of

underground pipe locating equipment to locate, identify and rectify any potential

unknown cross connected water lines. Then another wet/dry test will be repeated until it

shows comprehensive isolation.

During the implementation of water balance test for specific selected DMAs, a limited

customer survey will take place to upgrade CIS and GIS accordingly There are two

methods to quantify NRW, the first one is the Flow Balance (FB), and the second one is

Minimum Night flow (MNF). The flow balance (FB) calculation is the difference

between the total amounts of water supplied to a certain DMA with sum of the water

consumed within that DMA for a certain period of time. In case of have difference, this

difference could be leakage, metering inaccuracies or unknown water usage. Multiple FBs

calculation will be taken place for the selected DMAs at BA-8; one FB will be conducted

after isolation then the one will be after the implementation of each NRW reduction

activity such as disconnecting of the redundant mains, meter replacement, etc.

The second method is by conducting MNF which can provide information about the

level of physical losses. MNF will be carried out for selected DMAs at BA-8. In case of

having large number of customers MNF is considered easier than FB which would

require huge efforts to read all customers’ meters in a very short period of time.
