Hyderabad Metropolitan Water Supply and Sewerage Board (HMWS&SB) is planning to supply water to its consumers using solar power instead of electricity from conventional energy sources. Over the past decades, Hyderabad water board is using electricity from conventional sources for lifting, pumping, and distribution of water from off-take points of different drinking water reservoirs. Now, the board has planned to set up solar power plants on the surface of reservoirs, save electricity bills that run into anything between Rs. 80 crore to Rs. 90 crore a month.
The water board faces problem of power cuts when sub-stations go for repair and maintenance shutdowns. The HMWS&SB hopes to tide over this problem with the use of solar energy to pump water.
Detailed project report for this has been prepared. Water board will soon approach to Telangana State Renewable Energy Development Corporation Limited (TSREDCO) for implementation of the project. The cost of the solar project could be around Rs 500 Crore, and the water board does not have funds for it. According to the plan, the responsibility to float tenders and implementing the project will have to be carried out by the TSREDCO. In another week, the water board will discuss the plan with TSREDCO.
According to the DPR, total 15 million units of solar power per annum will be required to run water supply network in the city and GHMC periphery. The water board has already identified 50 reservoirs and pumping stations in around the city where solar panels could be installed.
