Domestic water supply in the city has been increased by three million litres daily (mld) for a week now to meet the rising demand in the summer months. According to a Chennai Metrowater official, the water supplied to domestic consumers through pipeline and tankers has been increased to 586 mld to match the rising demand. The total volume of water supplied to the city, including industrial and bulk purposes, has been increased from 645 mld to 650 mld. About 1,150 tanker trips are being operated to supply areas that do not have piped water supply. This would be further stepped up depending on the summer demand, he said. Residents' complaints However, residents of areas such as Koyambedu and Villivakkam complained that for a week now they are not getting piped water supply. Residents of Anna Nagar West said that water supplied through pipeline was murky for the past ten days. The official said the problem in these areas would have occurred due to local faults, which would be rectified.
