Maharashtra Jeevan Pradhikaran is a part of the Rural And Urban Development Ministry of the Maharashtra Government, for the construction and maintainence of rural regional and urban water supply scheme as well as drainage schemes.

This is a study of Amravati Water Supply Scheme with Upper Wardha Dam as a source, situated 55 km away from Amravati town. The energy required for pumping and conveying raw water from head works to treatment works is about 55% of the total cost of the M&R budget. Hence, the cost of production of water increases according to the rise in energy charges. In this study, attempts have been made to adopt various measures to develop a pumping system and a water distribution network for Amravati Water Supply Scheme.

• Scheme approved on 27th October 1986
• Designed to supply water at 120 lpcd for a population of 5.66 lakhs for the year 2001
• Scope to be extended to fulfill the demand of water in 2016 for a population of 8.6 lakhs

• Raw water abstracted from the dam through intake well
• Raw water pumped further by providing 750 BHP VT pumps to Break Pressure Tank (BPT)
• From BPT, raw water conveyed to 95 mld water treatment plant
• Pure water collected in Master Balancing Reservoir and then conveyed to various distribution reservoirs
• Lot of increase in the cost of production of potable water due to the energy cost
• Adopt measures for energy conservation:
  1. Development of energy efficient pumping system
     • Connecting suction pipe of VT pumps directly to intake from reservoir
     • Improvement in power factor and adjustment of pumping hours
     • Reduction in static head on pumps by constructing new BPT at lower level
     • Replacement of old 60 HP VT Pumps with HP CF Pumps
     • Replacement of bowl assembly of raw water pump set
  2. Distribution of water distribution network

• Reduction in the total loss from 51.78% to 17.10%
• Reduction in energy consumption from 571.8 to 405
• Reduction of energy cost per ml from 1704.26 to 1388.2 which resulted in the financial improvement

The system can be replicated in other parts of the city also.
