DJB announces workshop on using Treated Effluent for non-potable use
DMRC, DTC, DDA and Municipal Bodies among other Government Depts. to participate in the workshop
In order to bridge the gap between the demand and supply of potable water in the city and optimise the existing water resources, the Delhi Jal Board is actively promoting the use of treated effluent. Treated effluent, produced by DJB at its Waste Water Treatment Plants (WWTPs), is fit to be used for non-potable purposes, such as irrigation, horticulture, power plants, water bodies, construction activities etc., which will make additional water available for potable purposes.
In order to create awareness about treated effluent and to promote its usage for non-potable purpose among the various government agencies, DJB has planned to organise a workshop on 20th August, 2014. The workshop will focus on the potential uses of the treated effluent and will enable DJB to interact directly with other departments and help them understand the benefits of using treated effluent. It will also help DJB to address any doubt or concern on the issue, if any. DJB proposes to use this platform to present a global picture on the success of usage treated effluent across the world.
Various government corporations and entities such as the Delhi Metro Rail Corporation (DMRC), Delhi Transport Corporation (DTC) and the Railways consume huge quantities of water for washing and other need based purposes. Also, the Delhi Development Authority (DDA), Municipal Corporations and others use bore wells to meet their substantial demand for irrigational and horticulture purposes. Other government entities such as Pragati Power Corporation Limited (PPCL) and National Thermal Power Corporation (NTPC) also use a considerable amount of water for cooling purposes in their plants. The water demands by these government agencies put immense pressure on the existing limited water resources, which can be reduced by the potential use of treated effluent.
In an effort to promote the use of treated effluent, CEO, DJB, has written letters to various government departments encouraging them to use treated effluent for all non-potable purposes. The Hon’ble Lt. Governor and Chief Secretary, Delhi have also directed the above mentioned departments to use treated effluent as far as possible to help reduce the stress on groundwater and drinking water.
The current demand of the city is 1080 Million Gallons per Day (MGD) and DJB, with the limited available water resource, supplies 840-850 of filter water. With the use of treated effluent, it is expected that DJB will be able to meet the demand and supply gap of 240 MGD.
By December 2012, the Delhi Jal Board recycled about 142.4 Million Gallons per Day (MGD) of treated effluent. This makes DJB the only Public utility in India that recycles and uses 40 % of its treated effluent against the benchmark of 20%, as stated by the Urban Development Norm regarding the extent of recycling treated effluent.
