Dinesh Mohaniya, Vice Chairperson, DJB, Sh. Anil Kumar Singh, CEO, DJB, member of the Board and senior officials of DJB were present in the meeting. During the meeting, the members of the Board deliberated upon and approved key projects/ schemes to improve the water and waste water services provided by the Board.
Decentralized Sewer Treatment Plants (DSTPs) in Parks/Schools/Departments/Societies/Commercial Complexes/Industries/Colleges/Shopping Multiplex/Government Offices/Hospitals/Institutions:
The board in a major decision approved DSTPs to be created in parks all over the city. One of the major sources of ground water depletion is its extraction and use for horticulture purpose. There are large parks/ground areas of different agencies or large institutions/organizations green areas which use ground water/borewells for their horticulture need. The Board approved the proposal to enforce implementation of Decentralize Waste Water Treatment System (DWWTS) in Parks/Schools/Departments/Societies/Commercial Complexes/Industries/Colleges/Shopping Multiplex/Government Offices/Hospitals/Institutions etc. There are around 5000 Government/Aided/Pvt. Schools in Delhi.
All major parks and green belt areas whether with Delhi Govt./DDA/MCD etc. would not be allowed to use ground water anymore and instead they would make arrangement for DWWTS near to the feeding point provided by DJB, from where they would lift raw sewerage from the sewer line, treat it and use for their horticulture needs.
90% rebate on sewer charges: Board approved a 90% rebate on the sewer charges for all who use their own DSTPs for water recycling.
Study on use of 456 MGD water from STPs: Delhi generates 456 MGD water from its STPs every day. However, only 89 MGD of the treated water is used and the rest goes in drain. The board approved appointment of a consultant to study and submit a report on the use of the rest 367 MGD (456-89=367) water generated. The total amount of treated water will go up to 516 MGD by the end of 2018.
Rejuvenation of 12 water bodies: Board has appointed WAPCOS as consultant for revival and rejuvenation of 12 water bodies. It aims to recharge groundwater levels, improve ecology and create a green public space. Ground water can later be extracted to augment supply in the local area.
200 Sewer cleaning machines for narrow lanes/streets: The NCT has witnessed several unfortunate incidents/accidents concerning Safai Karamcharis in the recent past. In wake of this, the Board accorded approval for deployment of 200 specially fabricated tailor made sewer cleaning machines for cleaning of sewer lines in narrow streets/lanes in Delhi. The work comprises complete comprehensive maintenance of the sewer cleaning machines, including disposal of silt/garbage to the designated place as per direction of the engineer in-charge. The aim is to eliminate the practice of the manual cleaning of the sewer line so that the silt/sludge in the main hole is not handled physically by the labour and to avoid any mis-happening. The total expenditure for deployment of 200 machines shall be Rs. 380 crores.
The dependent individuals of the deceased engaged in scavenging activities, manual scavengers/Safai Karamcharis themselves, members of SC/ST and others in preference orders respectively.
Sewerage Master Plan 2031: The Sewerage Master Plan 2031 envisages complete coverage of un-sewered area/ colonies/ urban village etc. Keeping the plan in mind, the Board accorded the approval to below given projects:
· Providing and laying sewerage system, construction of decentralized STP’s and development of water bodies with 10 years Operation & Maintenance Cost in Chhattarpur Assembly Constituency in Delhi. The colonies in Chhattarpur Assembly Constituency fall under the commands of Okhla Sub Zone sewage generated. Presently, the sewage is being discharged into storm water drain and then to Yamuna River thereby polluting the water body.
· Providing and laying sewer line in Pochanpur Group of Colonies in Matiala Constituency at an estimated cost of 9.5 crores. The colonies covered in the scheme include Pochan Pur Extn. A Block, Pankaj Garden near Ambarhai Sector 19 Dwarka, Palam Vihar Dwarka Sector-6, Major Bhola Ram Enclave Sec.- 23 Dwarka, Pochanpur Ext. Najafgarh, C Block Pochanpur village, Gram Pustani Pochanpur Extn. Chander Vihar Palam Extn. Part-1, Palam Colony Adarsh gali Palam Gaon and Pochanpur Extn. B block, Najafgarh. The population to benefit after laying of sewerage system will be about 30,000.
· Providing and laying sewer line in Raghu Nagar group of colonies in Dwakra Constituency at an estimated cost of 14.73 crores. The unauthorized colonies covered in the scheme are Raghu Nagar, Syndicate enclave, Vashista Park and Mohan Nagar. The population to benefit after laying of sewerage system will be about 0.15 lacs.
· Providing and laying sewer line in the Dabri Village group of colonies in Dwarka Constituency at an estimated cost of 19.3 crores. The unauthorized colonies covered in this scheme are Dabri Extn. Vaishali, Dashrathuri, Dabri, Durga Park. The population to benefit after laying of sewerage system is about 50,000. The Dabri Village group of colonies will generate average sewage discharge of 1.50 MGD which will be ultimately connected to Waste Water Treatment Plant Dwarka for its treatment.
· Providing and laying sewerage services in Bakkarwala RSC (Loknayak Puram) at an estimated cost of 6.8 crores. Bakkarwala RSC is spread over an area of 20.23 hectare bounded by Bakkarwala Village in North and North- East, West by Lok Nayak Puram. The projected population to benefit after laying of the sewerage system will be about 20,000.
· Providing and laying 900/ 1000/ 1100 mm dia peripheral sewer line with micro tunnelling along the main Tigri Road upto Dakshin Puri SPS at an estimated cost of 13 crores. This peripheral seer line is an integral part of sewerage network of Sangam Vihar Group of Colonies Phase-I. The proposed peripheral sewer line will trap the sewage generated from the settlements/ unauthorized colonies along the MB road, which are presently flowing in storm water drains and contributes to pollution in River Yamuna. On completion of work, the chronic problem of sewer flowing in storm water drain is likely to be addressed thereby abatement of pollution in river Yamuna.
To bring about overall improvement in the water management system of Delhi Jal Board, the Board accorded approval to the below given projects:
· Creation of new raw water sources through high quality treated effluent from 10 MGD Waste Water Treatment Plant Narela after due up-gradation as per the standard being followed in under construction Coronation Pillar STP so that, the treated effluent discharged into the river Yamuna, upstream of Wazirabad barrage near Palla is of acceptable raw water standards at the pond. Thus, Waste Water Treatment Plant requires rehabilitation along with construction of new Effluent Pumping Station and laying of rising main towards Palla for discharging treated effluent into river Yamuna upstream of Wazirabad barrage.
· Providing, laying and jointing of peripheral water line network in the command area of Siraspur under Ground Reservoir at an estimate cost of 15.4 crores. The project will cater water supply requirement of villages Khera Kalan, Nagli Poona, Libaspur, Qadi pur, Ibhrahim pur and Garhi.
· Providing, laying and jointing of 700 mm dia feeder line form palla MBR to Siraspur Under Ground Reservoir at an estimated cost of 15.6 crores.

· Scheme for construction of UGR’s/BPS of 9.1 ML capacity at Bijwasan and 5.8 ML capacity at Rajokari Village including feeder mains and distribution mains at a cost of 31.5 crores. 2.15 lac residents will be benefitted on the completion of project.
· P/L Internal water distribution system in Jaitpur Extn. Part-II (Khadda Colony) in Badarpur Constituency at the estimate cost of 7.6 crores. Presently water is being supplied through local tube wells and water tankers and the residents are facing acute water shortage. Therefore, to facilitate the residents with safe and potable drinking water lying of internal water lines have been done as much water as possible in this colony.
· Delhi has limited sources of raw water and to meet the increasing demand of water for drinking, commercial and industrial use and environmentally sustainable manner, the Board has been developing plans to implement the recycle and reuse of treated effluent as source of raw water. To facilitate development of additional sources of water recycling of treated Waste Water is being adopted. DJB is setting up a 70 MGD MLD STP at Coronation Pillar. The board approved upgradation and rehabilitation of existing 40 MGD Rithala Phase-II STP to treat sewage to the standards of BOD and TSS<10mg/l. The tertiary treated effluent of standards BOD and TSS<10 mg/l produced from 55 MGD from Rithala WasteWater Treatment Plant Ph-I and II shall be pumped and terminated to proposed Coronation Pillar EPS of 125 MGD, from there it will be discharged into the river Yamuna upstream of Wazirbad Barrage. The discharged raw water in river Yamuna will be lifted from Wazirabad Pond for treatment to potable water standards by WTPs at Wazirabad.
