Abstract - The concept of 24x7 water supply to the city is
provides quality water to every citizen at optimal cost. Sector no.21 is currently provided with 24x7 water supply. PCMC has taken the work of converting intermittent to 24x7 water supply in 40% area of it.
not new thing but was in practice in late seventies but limited to some confined area. It deals with the fact that if the pipeline supplying water to the consumer is full for nearly 24 hrs, the tendency of the consumer to store the water more than their requirement is curbed. It further helps the maintenance engineer to detect leakages in the system and there by measure the quantity of water put into the system. The details like actual quantity of water consumed, water billed and the losses in the system can be ascertained easily.
C-14 at present receives water 2hrs a day. Although area is well planned there are certain problem reported by consumer and in order to tackle these problems PCMC decided to implement 24x7 concept in the said existing water supply scheme.
1.2 Types of Water Supply Systems 1.2.1 Intermittent Water Supply System:
The C-14 zone (Ajmera) at present receives water supply from Pimpri Chinchwad Municipal Corporation at a rate of 150lit/capita/day. Although the said area is well planned but there are certain problems reported by the consumers while maintaining the water supply scheme over the years. In order to tackle these problems PCMC decided to implement 24x7 concept in the said existing water supply scheme. This study reveals the modifications required in existing water supply network to make it suitable for continuous water supply. The main aim is transforming an intermittent into 24x7 water supply system in C-14 zone (Ajmera) of PCMC. Data required for study is collected from Water Treatment Plant, and from field surveys & visits. Existing network is hydraulically modelled using WaterGems software. Modifications required such as pressure reducing valves, parallel lines, isolation valves are identified and rectified accordingly.
1.1 Introduction of Project PCMC : Pimpri Chinchwad Muncipal Corporation (PCMC) is located on Mumbai Pune highway, covers an area of about 181square km. PCMC is considered as richest and one of the fastest growing Municipal Corporations in Maharashtra. PCMC takes many efforts to provide reliable services to the citizens. Water supply is major part of it. It

Generally water is supplied at peak hours i.e. in morning 6 am to 9 am and evening 5 pm to 8 pm.
In India this system is generally followed by many cities.
In this system consumer needs to store water during supply hours.
In this system water is supplied to the users 24 hrs. a day and 7 days a week.
The water is adequately pressurized to reach consumers end.
Consumer need not to store the water.
Wasting of water is avoided.
1.3 Advantages of 24x7 Water Supply Scheme

In this system water is supplied to the users for less than 24 hrs. for specified period.

24x7 system reduces contamination level as the pipes are under positive pressure and entry of contaminants into the pipes is restricted.
Steady pressure in the pipe increases life of pipe distribution network.
A better demand management is possible due to metering system and effective leakage control. It is also easy to calculate water charges based on consumed volume.
