Ahmedabad City Water Supply
Background & Objective
Ahmedabad is located in the arid region. Average rainfall is about 740mm per year. Main source of water was sabarmati and ground water.
Continuous drawing of water by tubewell pumping has resulted in rapid depletion of ground water table and increase concentration of total solids, chlorides and fluorides.
The main objectives of the initiative are to:
- Provide wholesome, adequate, regular daily water supply to all citizens
- Stop the use of ground water source by 2009-2010
- Supply of safe drinking water (as per Drinking Water Standards)
- Test the water at each stage upto the consumer's end by having well-equipped labs and publish the same on websites and in newspapers to make the citizens aware
- Implementation of e-governance for grievances and complaints related to water supply for each ward in the year 2001-2001
- Public awareness by means of various media.
Implementation
Due to the shortfall in water from Sabarmati river and ground water sources, new sources were commissioned.
- To meet the demand for water, it was planned to procure water from Mahi canal through the Raska Weir Water project.
- The Narmada Canal alignment was planned by GoG.
- 3 treatment plants were installed.
Output & Outcomes
- The scenario of the water source changed.
- The ground water scenario has also changed.
