Supply of Potable/ Filtered water
The installed capacity of Water Treatment Plants is 631 MGD and by optimization through Tubewells, Ranney Wells etc., about 650 MGD potable water is being supplied by Delhi Jal Board. It is expected that by the end of 9th Five Year Plan i.e. 2002 water requirement in Delhi shall be 945 MGD.
Delhi Jal Board is committed for augmentation of water supply in Delhi and has taken many steps in this direction. 40 MGD Water Treatment Plant at Nangloi has been commissioned. The work of construction of 20 MGD Water Treatment Plant at Bawana is in the final stage of completion. The work for construction of 140 MGD Water Treatment Plant at Sonia Vihar in trans-Yamuna Area has started and is likely to be completed within two years. Simultaneously, UP Jal Nigam has also started the work of laying of raw water conduit from Murad Nagar to Sonia Vihar. On completion and commissioning of these water treatment plants the filtered water supply in Delhi will improove.
With a view to rationalise the distribution of water Delhi Jal Board has drawn up an elaborate plan for construction of Under Ground Reservoirs and Booster Pumping Stations(UGR/ BPS). Durring the Year 2001 the UGR/ BPS at Dakshin Puri, Farid Puri, Shadi Pur, Mangol Puri and Chitranjan Park have been completed and commissioned. The work on 13 Under Ground Reservoirs and Booster Pumping Stations is in progress.
We are also active in the field of water conservation and have a separate Leak detection Cell for detecting various leakages in the system. Special campaign for public awareness on water conservation has also been successfully implemented through extensive media coverage. Special stress has been given on replacement of old water lines and during the year about 208 KMs of old eroded water lines have been replaced in different parts of Delhi.
Rapid urbanization has put tremendous pressure on the existing civic services including supply of drinking water in Delhi. This has resulted in drastic decrease in ground water table in Delhi. This could be avoided through a simple, economical and eco-friendly method of rainwater harvesting. We have decided to implement Rainwater Harvesting schemes in all our buildings/ installations including our Headquarters at Karol Bagh. In addition, Resident Welfare Associations are also being involved for implementing this simple method of water harvesting.
Bhagidari Scheme is being implemented by DJB in which more than 100 Resident Welfare Associations are actively participating and it covers following subjects:
- Rain Water Harvesting
- Distribution of Water through tankers.
- Replacement of old /leaking service pipes.
- Water bill payment and collection.
- Curbing wastage of water.
Quality Assurance Measures
Water supplied by the Delhi Jal Board is not only potable and wholesome but also conforms to the standards laid down by the Urban Development Ministry, Govt. of India. Quality assurance measures are taken right from raw water stage up to the consumers end. The water supplied from Ranney Wells and tube wells is also tested regularly. Water samples are collected daily from the distribution system i.e. individual taps and public hydrants etc. located in different parts of the city to ensure that safe drinking water reaches the consumers. Efforts are also being made to achieve ISO 9002 certification for which DJB is in touch with Bureau of India Standards.
With a view to avoid contamination of water because of service lines passing through drain sewers, 10789 cases were identified and notices were issued to consumers for shifting of their water lines. 3687 such connections were dis-connected and 4899 consumers shifted their service lines themselves.
Treatment and Disposal of Waste Water
Delhi Jal Board is responsible for treatment and disposal of waste water through an effiicient network of about 5600 KMS of internal, peripheral and trunk-sewers. The capacity of Sewage Treatment Plants has been raised from 376.4 MGD to 402.4 MGD during the year 2000-2001.This capacity is further proposed to be increased to 512.4 MGD by next year. Out of 17 Sewage Treatment Plants (STP) under construction the work of 12 has been completed and the work of remaining 5 STPs is under progress.
The DJB has provided sewage facilities in all the approved colonies. Out of 567 unauthorized /regularized colonies, 414 colonies have been provided with sewage system and we have laid sewer lines in all re-settlement colonies also. Sewer lines have also been laid in 93 urban villages.
