The foursewage treatment Plants(STPs) at Beur, Karmalichak, Saidpur, and Pahadi inPatnawill be made functional by the end of the 2021-2022 financial year. Sewer networks are being laid to connect all the households to the STPs so that untreated water does not get discharged into the Ganga directly.
The foundation for the plants, which have a capacity to treat 200 million litres of wastewater per day, was laid by Prime Minister Narendra Modi at Mokama in Patna district in October 2017.
According to sources, the wastewater will be treated through sequencing batch reactor system and used for Irrigation after chlorination.
Two other STPs at Digha and Kankerbagh are in the initial stage of construction. While the one at Digha will have a 228km-long sewer Network, the Kankerbagh STP will have a 150km-long sewer network.
