NEW DELHI:05.10.22-Delhi Government under the leadership of CM Shri Arvind Kejriwal is working on a mission mode to ensure the cleaning of the Yamuna by 2025, provide 24x7 clean water supply to each household in Delhi and connect the households in all unauthorised colonies with sewer lines. Taking forward the work in the same direction, Deputy Chief Minister Shri Manish Sisodia approved the various projects of the Delhi Jal Board (DJB) recently. These projects include the construction of decentralised sewage treatment plants in several areas of Bawana and Mundka, the laying of sewer lines in various unauthorized colonies and rural areas of Delhi and the construction of 2 MGD wastewater treatment plants at Bawana. The total cost of said projects is Rs 570 crores. The projects will help the Delhi government in achieving the target of clean Yamuna by 2025 and resolving the sewage issues across unauthorized colonies in Delhi. Deputy Chief Minister Shri Manish Sisodia directed the officials to complete all the projects in the stipulated time.
Sharing the details about the project, Deputy Chief Minister Shri Manish Sisodia said, “The Delhi Government is working in a phased manner to upgrade the sewage system of the capital and ensure that no polluted water is released in the Yamuna. For this, the government has decided to set up decentralized sewage treatment plants (DSTP) in unauthorized colonies and residential areas. While it is not easy to lay pipelines all over the place for large STPs, it is possible to construct low-capacity DSTPs at a low cost. The decentralized sewage treatment plant will relieve the burden of rising water pollution, foul smell and depleting groundwater level in most of the colonies of Delhi. The space available for their construction will be used sparingly. The DSTP will be an aesthetically good option and there will be no compromise on the public convenience because of them.
*Delhi Government will lay sewer network in rural areas of Mundka along with the construction of 26 MLD capacity DSTP*
Deputy Chief Minister Shri Manish Sisodia said, “Apart from the construction of DSTP, WWPS, sewer lines will also be laid in the colonies of Nizampur, Ghevra, Kanjhawala, Mohammadpur Manjri under Mundka assembly constituency. Here 1 MLD DSTP in Garhi Rindhala, 6 MLD DSTP in Nizampur and Savda, 2 MLD DSTP in Ghevra, 2 MLD DSTP in Jonti and Tatesar, 5 MLD DSTP in Kanjhawala and Ladpur, 10 MLD DSTP in Mohammadpur Manjri and Karala will be constructed. Decentralized sewage treatment plants with a total capacity of 26 MLD will be set up in all these areas. Apart from this, sewer lines will be laid in the adjoining colonies including Jonti-Tatesar village, Mohammadpur Manjari and Karala village of Mundka. At the same time, the Kejriwal government will lay sewer lines to solve the sewer problem in Kanjhawala and Ladpur villages, Nizampur and Savda, Ghevra villages as well as nearby colonies.” He added that with this, lakhs of people in the area will get relief from sewerage problems. The government will spend Rs 427.6 crores on the project of laying decentralized-sewage treatment plants and sewer lines in these rural areas falling under the Mundka assembly constituency.
*Decentralized sewage treatment plant to be constructed in Bawana*
Shri Manish Sisodia said that sewage treatment of individual households in some villages and unauthorized colonies of Bawana assembly constituency and sewerage network at various places according to the availability of land in this area to prevent contamination of water in Yamuna river and decentralized sewage treatment plant will be constructed. This will benefit lakhs of people in 9 villages including a total of 24 unauthorized colonies here. The cost of this project will be around Rs 132.6 crore. In the present scenario, sewage from households in these areas is getting discharged at the Yamuna. In such a situation, with the construction of a decentralized sewage treatment plant here, the sewerage will help in reducing the pollution of the Yamuna.
*What is a Decentralized Sewage Treatment Plant?*
The decentralized sewage treatment plant is a mechanism in which a small sewage treatment plant is installed, with its help the wastewater can be treated at the same place from where it is generated. The government of Delhi aims to solve the problem of water irrigation in more and more parks and other places of Delhi through decentralized STP. Presently the sewage treatment plant is located in one part of the city and there the waste water is brought through different channels and costs much to the government. At the same time, decentralized-sewage treatment plants will be installed inside the colonies, which will solve the problem of water pollution as a lot of sewage water will be diverted to DSTP. The recycled water from DSTP can be used for gardening and the excess water will help in recharging the groundwater.
*DSTP is different from the existing model of STP*
A decentralised sewage treatment plant is a system of treating contaminated water at its origin. Presently, Sewage Treatment Plants (STPs) are set up at remote locations in the city and water is collected for these from various sources. Sewage treatment plants eliminate disease-causing bacteria from contaminated water. Sewage water contains both garbage and other types of dirt, which consists of waste from homes, offices and industries, so its cleaning is very important. The STP plant treats this contaminated water through an expensive supply system. It is not easy for large STPs to lay pipelines in all parks and everywhere, whereas decentralized STPs of low capacity can be constructed at low cost. Apart from this, no additional pipeline is required to be laid. The sewerage of the surrounding area is treated by bringing it to a decentralized STP. Therefore, D-STP is a sustainable option for treating large quantities of water.
*DSTP will be constructed at these places in Bawana*
DSTP and SPS of 1 MLD capacity will be constructed in Punjab Khori and Jat Khori in Bawana by the Delhi Government. At the same time, 4 MLD capacity DSTP and SPS will be constructed in Auchandi, 3 MLD capacity DSTP and SPS in Qutab Garh and 10-10 MLD capacity DSTP and SPS at Bajitpur Thakran.
*2 MGD capacity water recycling plant to be built in Bawana*
A 2 MGD capacity recycling plant will be constructed in Bawana to recycle the waste water from the existing 20 MDG WTP. It is to be noted that 20 MGD WTP in Bawana was constructed in the year 2000. It is already functional and can operate an additional 2 MGD water recycling plant with the deployment of a few employees. According to the Delhi Jal Board, a lot of water is being wasted due to the absence of any recycling plant for this WTP at present. In such a situation, water wastage will be prevented through 2 MGD recycling plants to be built at a cost of Rs 10.3 crore. Its work will be completed in about one and a half years.
