17 STPs coming up along River Musi
Will have a total treating capacity of 376.5 MLD
Hyderabad: As part of its efforts to ensure flow of treated water into the Hussain Sagar and to decentralise sewage treatment in the city, the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) has initiated work on setting up 17 Sewage Treatment Plants (STP) along River Musi and on the Kukatpally Nala catchment with a total treating capacity of 376.5 million litres a day (MLD). The initiative is being taken up as part of the Hussain Sagar catchment development under the sewerage improvement project and Sewerage Master Plan of the Hyderabad Urban Agglomeration area.
Apart from the Banjara, Picket and Balkapur nalas, the Kukatpally nala is one of the major inflow channels into the Hussain Sagar. About 155 MLD of sewage water flow into the Hussain Sagar through the Kukatpally nala. Along with sewage, a lot of trash, plastic waste and other effluents too flow into the lake through the nala.
Municipal Administration and Urban Development Minister KT Rama Rao had directed the HMWSSB to initiate measures to arrest the flow of sewage and ensure flow of clean water in the nala. Currently, HWMSSB treats 772 MLD of waste water through 25 STPs in different areas. While most of cities are equipped to treat only 20 to 30 per cent of the sewerage generated, the HMWSSB is treating nearly 43 per cent in the city. In the Greater Hyderabad Municipal Corporation (GHMC) limits, nearly 1,781 MLD of sewage is generated, of which about 772 MLD is treated through the HMWSSB’s STPs, officials said.
The idea is to decentralise the treatment of murky water in the city. At present, the sewage water is treated at Amberpet, Nagole and other STPs. Under this initiative, HMWSSB is now working on construction, installation, testing and commissioning of 17 STPs with a total capacity of 376.5 MLD.
These STPs will be equipped with Sequential Batch Reactors process technology and will come up at various locations. As part of agreements, the entire units will come with a warranty period of two years for equipment and instrumentation from the date of commissioning of the plant, including manning, operation and maintenance for a period of 15 years. More importantly, the foundation of all the units will be designed in a way to facilitate upliftment in the future as STPs are located near the foreshore of water bodies.
