Delhi Jal Board step to increase use of treated effluent

NEW DELHI: In a bid to increase use of treated effluent for irrigation, horticulture, construction etc, Delhi Jal Board has installed filling points at its major waste water treatment plants. It has also written to other government agencies, asking them to replace potable water with treated effluent for non-drinking uses.
DJB sources said filling points have been provided at the Kondli, Rithala, Coronation, Keshopur, Mehrauli and Okhla treatment plants."The biochemical oxygen demand (BOD) of the treated effluent is less than 20 parts per mission while total suspended solids (TSS) are less than 30ppm, making it ideal for non-potable purposes. We are distributing 142.2 million gallons per day of treated effluent. The irrigation department takes effluent from the Keshopur , CPWD and Institute of Clinical Research India & Irrigation Department from the Okhla , Maharashtra Industrial Development Corporation from the Coronation Pillar, Pragati Power Corporation Limited from the Delhi Gate and Sen Nursing Home Nallah s. There is a total of 330 MGD of treated effluent available," said sources.
Officials said that a 10 million litres per day tertiary treatment plant is under construction at Okhla for supply of treated effluent to DTC for bus cleaning and use by industries in the Okhla Industrial Area. Another 40 MGD is being constructed at Coronation Pillar which will be used as a source of raw water for treatment at Wazirabad. This treated effluent will be of almost close to drinking water quality and will be added into the Yamuna at Palla to help generate more flow in the river.
