INTRODUCTION

This visit report covers the activities of energy management consultation and training project. This project is funded by the U.S agency for international development for which resource management associates of Madison.inc serves as the prime contractor in implanting the project Under this contract, RMA provides energy efficiency consulting services to India.

BACKGROUND Pune is a city of approximately one and a half million inhabitants, located in western India in the state of . Pune has a thriving metro business, climate, with many industries located in the vicinity of the area Over the past years, Pune has buoyant services of revenue and a significant surplus. This has to undertake a majority of the capital investments in urban infrastructure from its own revenue surpluses. As a result, PMC has a relatively low level of understanding debt.

EXISTING SYSTEMS One of the first water supply schemes in Pune city was through a small dam constructed on the river Amba near . From this water was supplied to the city through a pipeline. Later a small bund area was constructed on the . In the year 1848 the supply of water to Pune cantonment over the time, with the growth in population, these two reservoirs proved inadequate and a large reservoir was a dam at Khadakwasla about 25 kms from the city

TRANSMISSION AND DISTRIBUTION Currently, the PMC supplies water to the population with the limit, as well as fifteen surrounding villages. Even though the supply levels are fairly adequate compared to other major cities in India, there are certain pockets in the periphery and nearly developed areas that do not receive adequate supply and pressure In addition, the PMC limits are expected to be increased during the current year, with the merger of thirty-six surrounding villages, which will have to be provided with basic services, such as water sewage. The corporation is also required o provide water supply to the surrounding villages within 5kms of municipal limits as per the recent state government directive. The thirty-six villages that are likely to be merged will impose a severe burden. It is in the context of likely growth in water demand that PMC proposes to augment the water supply services

OBSERVATIONS Several important characteristics are observed at the Parvati water works. The main observation was that significant number of pumps and valves wee leaking. In fact, one tank was also leaking and two or three cracks in the concrete were visible, while this situation is fairly typical in India, it is not typical in western countries. There was a small gantry girder which was used for carrying heavy loads

QUESTIONS 1. What are the coagulants add in water for removing turbidity? 2. How much time is required for sedimentation? 3. How many stages are made for purification? 4. How is backwashing done? 5. What is pre-chlorination and post chlorination?

Summary

This visit covers an all the points required for the students to know about how the water purification is done. Even during the visit we got to know about the life of building which was going to get over i.e. 50 years. The points on connections (rivet, bolts and weld) were discussed too
