"About 93 per cent households of Delhi now have access to piped water supply. Water production during summer season is being maintained at 956 MGD per day consistently. Water is supplied through existing water supply network comprising 15,383-km long pipelines and more than 117 underground reservoirs (UGRs)," the DES said.
Total of 397 new water tankers with stainless steel containers fitted with GPS have been engaged in improving the water tanker supply delivery system in the city, the it noted. The DJB has initiated projects for installation of flow metres for water auditing and streamlined its system for obtaining water meters for metering of unmetered supply of water.
The report said the board is carrying out rejuvenation of 67 water bodies out of which rejuvenation work at 42 water bodies has been completed and tender for 25 will be called shortly.
