New Delhi: Delhi government has decided that it will use treated the city sewage water to augment the city water supply on large scale. Due to the water shortage, disputes with Haryana and the prospect of rejuvenating the Yamuna. On Tuesday, New Delhi CM Arvind Kejriwal announced that the city will start following the ‘Singapore new water police’ by using wastewater to augment 15 to 20% of its water supply in next two years.
“DJB has an installed water capacity of 900 mgd (million gallons per day) and we will start using 70 mgd water from Coronation Park treatment plant by June next year as a start,” said Kejriwal. “ Water will be drawn back at Wazirabad and treated again for reuse as ‘new water’. In the second phase, 40 mgd water will be diverted from Rithala by December 2019 and another 40 mgd by June 2020. It will be an overall improvement of 150 mgd,” he added. “ Borewells will be set up along the periphery of these lakes to exploit the increase in groundwater levels. Landscaping around the water bodies is also planned. The water will percolate to the ground and improve the groundwater levels in the vicinity” CM added.
Groundwater quality testing will be carried out at a place where the water table is very high and sets of borewells will be installed with the cooperation of RWAs to extract water at positive locations. Mini – treatment plants would set up to compensate the loss,” said DJB vice chairman Dinesh Mohaniya.
