DJB produces treated water for non-potable purposes

In order to stop usage of fresh water for non-potable purposes, Delhi Jal Board has built a Tertiary Treatment Plant of producing 10 million litres per day capacity at Okhla.
According to a senior official, plant has been commissioned recently and is producing high quality water from sewage which can be used for non-potable purpose.
Water from the plant is being used at DTC depot at Sukhdev Vihar for washing buses saving 50,000 litres of ground water every day, the official said.
"DJB has started supplying recycled water from the plant to the DTC Depot at Sukhdev Vihar for washing of buses. Earlier, ground water was being used for washing of buses which has now been stopped," an official said, adding that using recycled water for bus washing will enable a saving of 50,000 litres of ground water every day.

In its bid to promote the use of treated effluent for non-potable purposes, DJB is also laying pipelines in Okhla industrial area phase-II to supply recycled water from the newly commissioned Tertiary Treatment Plant for industrial and other non drinking uses.
"Supply of recycled water to Okhla industrial area will start in six months and will save lakhs of litres of ground water and drinking water. Other potential uses of recycled water are also being identified," the official said.

With the use of tertiary treatment, DJB is ensuring that recycled water of substantially improved quality is available for re-use. This will reduce stress on drinking water, reduce extraction of ground water and bridge the demand-supply gap.

"The proper disposal of treatment plant effluent is an essential part of planning and designing wastewater treatment facilities. DJB is doing a commendable job of promoting use of treated effluent for non-potable purposes and at present 420 MGD of treated effluent is being produced at all the 36 Wastewater Treatment Plants of DJB.
"This government is looking to use all of this water for non-potable purposes to reduce stress on potable water," Kapil Mishra, Minister for Water and Chairperson, Delhi Jal Board, said.
