The Delhi government will construct 22 MGD Sewer Pumping Stations (SPSs) and 15 MGD STPs at Jindpur in Narela Assembly constituency and 9 MGD SPSs at Hiranki. This project will benefit about 4.17 lakh people of 40 unauthorised colonies and 14 villages of Narela and Burari. After meeting with the Delhi Jal Board and other stakeholders, Delhi Deputy Chief Minister Shri Manish Sisodia informed that a 15 MGD capacity STP will be constructed in Jindpur by the DJB.
After the commissioning of this STP equipped with modern technology, the Biological Oxidation Demand (BOD) level of the sewage water will be purified and brought up to 10. Along with this, emphasis will be laid on the reuse of treated water from this STP. The treated water coming from the STP will not only help in cleaning the Yamuna but is also useful for other activities as well. This can be used for purposes like horticulture and rejuvenation of Delhi's lakes, etc. to meet the growing demand for potable water.
Sisodia said that after the commissioning of the STP equipped with modern technology to be built in Jindpur, the Biological Oxidation Demand (BOD) of the polluted water will be purified and brought up to 10.
“Due to this, about 12.45 MGD of sewer water will get purified and fall into Yamuna. Actually, the biochemical oxygen demand (BOD) of sewer water is up to 250. The sewerage water is treated and brought up to 10. After this, it is released into the drain. Two things are seen in the treated sewer water. The first is BOD and the second is COD. BOD is the amount of oxygen that is consumed by bacteria decomposing organic matter under aerobic conditions,†he said.
The Delhi government has decided to construct 22 MGD SPS in Jindpur and 9 MGD SPS in Hiranki to pump sewer water to STP. Sewage Pumping Station (SPS) will play an important role in making the water reach the STP from the houses which are connected to the internal sewer line. The sewerage will be sent to STP through the motor pump in SPS.
