Safe & adequate water readily and conveniently accessible by users at all times and in all situations.
Intermittent supply gives rise to the following deficiencies in the service and its management:
Serious risks to health, resulting from ingress of contaminated groundwater to the distribution system;
Inability to practice efficient supply management; Inability to practice effective demand management; Operational inadequacies which unduly weaken the physical
infrastructure; Customer dissatisfaction with an unreliable service of poor quality. Customer inconvenience, in many cases to an unacceptable degree,
by limiting personal water usage to below the level required for the practice of safe hygiene and translating into an unwillingness to pay for a sub-standard service.
How this contaminated water can enter water distribution pipes when they have been emptied down at the end of a supply period.

Schematics view - Showing If a distribution system is continuously pressurized, it is not possible for contaminated groundwater to enter the pipes, even when there are breaks in the pipes and joints.
A continuous, 24-7 supply is the norm in the rest of the world. All developed countries have continuous water supply systems. In the United Kingdom, for example, if the water supply to an area must be interrupted, for whatever reason, the water company must pay a monetary penalty to every customer in that area for every day that the supply is interrupted for a given number of hours.
The question of affordability can be viewed from two perspectives from the perspective of the customer of the water service; and from the perspective of the overall economics of the entire system and the provision of a cost-effective service.Punjab experience shows that intermittent water supply can be converted to 24 X 7 water supply with minor additions.
Making aware and sensitizing the people of the village about the scheme. Generating Participatory Rural Appraisal. Forming Gram Panchayat Water Supply Committee.Providing Capacity Building Training. • Training on project concepts,• Role of GPWSC/GP/Opinion Leaders during pre- planning &
planning phase .• Training on quality aspects in implementation phase.• Training for operation and management aspects to the Pump
Operators/Technicians, officials handling the Accounts and Billing (post implementation phase).
Effective Monitoring & Training Is Essential
Meters Successfully address the issue of unequal distribution of drinking water,
Misuse of water by advantage groups, Constant complaints about inadequate supply of drinking water. Non-payment of water tariff due to poor services and unbalanced
budget leading to huge pending electricity bills and diversion of development funds towards maintenance of schemes by the GPs.
Meters save water and energy cost. Eventually, every household gets water supply and pays according
to what it uses. The meters also trigger the professionalization of the GPWSCs . GPWSCs begin to hire and manage technical staff,
Fix and adjust tariff to fully cover increasing operation and maintenance (O&M) cost.
Charge on volumetric basis, and develop a computerized billing and collection system. In fact, GPWSCs manage their water supply systems on a utility management model.
The introduction of meters helps the GPs, with support from GPWSCs, to fulfill the requirements of Government along with delivering a much better service.
GPWSCs managing piped water systems with metered connections are able to meet O&M expenditure in a better way.
Enhance transparency of the working of GPWSC making them better equipped to report to GP authorities and the Gram Sabha.
Intermittent supply can be converted into 24 X 7 Water supply by installing a liquid level controller in the Over Head Service Reservoir & by installing meter in each & every household of the village and by employing an effective revenue management system. It is not costly as the investment on these items can be offset by the benefits of reducing non revenue water.
Revenue management system is an important aspect of any Water supply System to make it self sustainable. Besides fixing a tariff structure, billing and collection of revenue play an important part.
A bulk water meter of 100 mm size has been installed at the entry point of each village to measure the quantity of water supplied to the village.
15 mm size water meters have been installed inside the houses by DWSS. In case of malfunctioning of meters, the manufacturer has to rectify it free of cost for a period of one year.
Thereafter, the GPWSC through identified mechanics shall maintain a system of meter maintenance arrangements.
Meter readings in each house is undertaken by pump operator / cashier on 25th of every month. The meter reading record is maintained in a register.
The signature of every consumer is taken on the register about the correctness of meter reading.
The monthly tariff has been fixed by the GPWSCs by taking into account the expenditure on the following heads to make GPWSC self sufficient.
• Electricity Charges for running of machinery.• Establishment Charges.• Repair of Infrastructure such as machinery, pipe lines &
Civil structure.• Cost of disinfection.
At present the water bills are prepared by cashier but soon preparation of the bills will be outsourced to a computer agency.
DWSS has already outsourced the preparation of water bills to the “Department of Electronics and Accreditation of Computer Courses (DOEACC) , Sector 17 Chandigarh”.
GPWSC shall be persuaded to outsource the preparation of bills to DOEACC. The agency would charge Re.1 for the preparation of each water bill which will be borne by the consumers/GPWSC on trial basis.
Collection of water bills is done by the Pump operator/ Cashier. In case of any default in meter during use, an average bill of previous three months usage will be charged.
The GPWSC will supply new water meters in lieu of faulty meters. The charges for the new meter will be borne by the consumer.
If any consumer is found guilty of misusing the water, his water connection will be disconnected & reconnection charges will be met by the consumer.
From the experience gained by the Department it can be concluded that without metering 24 X 7 water supply status cannot be achieved.

The Water supply scheme Paprala is situated about 45 km from Chandigarh on Chandigarh- Ropar Road. This village is about 2 km on left side from main road.Population: - The present population of the villages Paprala, Railon Khurd & Rasulpur are about 922, 713 & 521 having 160, 115, 85 drinking water connections respectively.Previous water supply System: - Previously these villages were NC villages. Residents were facing great scarcity of water as level of water used to fall gradually during some season.
The proactive people of village Paprala, Railon Khurd & Rasulpur unanimously decided to approach Rural Water Supply and Sanitation Department Punjab to get World Bank Aided Project in their village. Department officials visited these villages and hold preliminary dialogues with the community on their needs, problems and priorities in relation to water and sanitation and they asked the villagers to collect their beneficiary share of Rs.1500/ household and people were made aware about the ill effects of the contaminated water and water borne diseases. Gram Panchayat Water Supply Committees were formed under the Prime Chairmanship of S. Dial Singh (Sarpanch) according to World Bank guidelines and with cooperation of members collected their beneficiary contribution to the extent of Rs 5.02 lacs.
As per guidelines of the World Bank Project, GPWSCs were constituted and resolution in this regard was received on 07-12-2005. The GPWSC was approved by District Water Supply and Sanitation Committee. GPWSC has opened bank account in State Bank of Patiala, Ropar. The committee collected 100% beneficiary share and deposited in bank account. Digital Survey of the village was conducted. DSR was prepared and submitted to Govt. for approval. Pb. Govt. No. 168 dt. 12.1.06 for Rs. 55.19 lacs & was technically sanctioned by C.E. (south) Patiala No. 50024 dt. 9.10.2006. The bid of the work of this scheme was prepared and sanctioned in five packages. The tender was called through press and on World Bank Website from 28-05-2007 to 28-06-2007. The tender of five packages of this scheme was approved by tender accepting committee in the month of August, 2007. The work was commissioned in the month of Aug, 2009 and handed over to GPWSC in the month of Sept, 2009 for O & M.
Design features: The GPWSC started the O & M with the help of
Department but in the beginning the wastage of drinking water was very much and committee could not control the wastage. Due to this the expenditure on electricity bill and other expenses was high and savings of the committee was not very good. The Committee discussed this problem with the department and demanded water meter at every connection.
Technical Parameters: The department installed 90mm, 90mm &
75mm size Bulk Water Meters at water works for villages Paprala, Railon Khurd & Rasulpur & individual water meters of 15mm size at every connection. So that wastage of drinking water can be controlled. Sr. No. Name of Village No. of Meters Cost of Metering

2. Railon Khurd 115 1.23
3. Rasulpur 85 1.00
Financial Parameters: Before the installation of water meter, running of
motor was 6 to 7 hours a day and consumers get only six hours water supply in a day. Now the running of motor is 5 hours a day and consumers get 24 hours water supply. The electricity bill prior to installation of meter was Rs. 11000/- and after the installation of water meter the average electric bill is Rs 8000/- . The flat rate prior to installation of water meter was Rs. 75/- per household. Now tariff is Rs. 30/- per house hold as monthly minimum charges plus Rs. 5/- per kilo liter. The villagers have no necessity for any kind of storage and saved their time. Now the wastage of water is below 10%.
Social Parameters: The health of villagers improved due to 24 hours
drinking water supply and sufficient time is devoted to their agriculture activities. On this account the financial position of the villagers has also improved. It has also improved the health of domestic animals resulting the increase in milk production. After interaction with the village people it has been noticed that after commissioning of this water supply scheme, general health of people has improved to considerable extent.

Both rich and poor will benefit from a properly managed continuously pressurized (24/7) supply system. Despite the fact that many people still regard 24/7 water as a luxury for the rich, it is actually the poor who will observe the greatest improvement in their lives. While most upper income families have already invested in storage tanks, pumps and treatment systems in order to compensate for their water board’s failure to provide 24/7 service, the poor can never afford such investments.
Usually water supply is made twice/thrice a day to the village community at the rate of 3hrs each time which is equal to 6 hrs. Alternatively due to non-availability of power in the day time, the distribution hours may be restricted to 4 hrs a day. It may be further kept in mind that demand of water is more in the morning shift which may be 1.25 - 2.5 times of the average daily demand. Hence peak factor for designing the distribution system shall be worked out.
Calculation of peak flow rate for designing the peak flow rate:
Case - Supply time : 6 hrs. Average Daily Demand: Q LPD Total water supply duration: 6 hrs. Average supply rate: 24/6xQ =
4Q Morning peak rate: 2 So design peak rate: 2x4Q = 8Q
The size of distribution pipe shall be calculated on the basis of discharge to be carried by the pipe line, pressure requirement and number of connections to be drawn form the pipe by using following formula:Number of connections = [D^2/d^2]
Where ‘D’ is diameter of main pipe & ‘d’ is the diameter of pipe. For example if diameter of main pipe is 150mm & branch pipe is 90mm then number of branch pipe connections = 3.58 say 3.
Maintaining low or no NRW (Non Revenue Water).
Ensuring regularity in user fee collection.
Water conserving habits of people.Populist policies of the successive
Governments. Meter Maintenance.
Keeping in view the success achieved in
villages like Singhpura & Sitabgarh it is proposed
to adopt this model of 24 X 7 metered water
supply in at least 50 villages in this financial year.
As mentioned in this presentation we have
achieved already 24 X 7 in 11 villages & others are
underway.
24 X 7 water supply costs less to operate & provides high benefits.
