PWD to use recycled water for horticulture

Delhi’s Public Works Department (PWD) has decided to use recycled water from sewage treatment plants of Delhi Jal Board for its horticultural requirements. PWD’s move comes a few days after DJB requested it to promote <g data-gr-id="22">use</g> of recycled water for <g data-gr-id="23">non-drinking</g> purpose.

A senior government official said groundwater is presently used by PWD for watering plants on the central verge and in parks and lawns, but from next month the use of recycled water will be mandatory to meet horticultural needs. According to <g data-gr-id="26">government</g>, the new move will prevent extraction of ground water in a big way and 1.75 million litres of groundwater will be saved daily.

“DJB has made available to the PWD the list of locations of hydrants for recycled water installed at various waste water treatment plants (WWTP) across Delhi.

“All agencies providing water to various sites of PWD for irrigation or horticultural use through agreements shall switch to supplying only  recycled water,” the official said.

He added that all such agencies have been asked to make this switch by October 5 at the latest.

“PWD has also agreed that in future, agreements and tenders would clearly specify that the source of water for horticultural purposes is from WWTPs,” he said. 

Delhi Water Minister Kapil Mishra, also DJB’s chairperson, said:  “Recycled water can satisfy most water demands as long as it is adequately treated and is appropriate for the use. To reduce the burden on potable water, it is important to use recycled water for non-potable purposes.”
