M/s. En-Vision Environmental Services is working with Telangana Government on 19 sites in Rangareddy and Medchal-Malkajgiri Districts for Faecal Sludge Treatment Plant (FSTP) project and will continue the operation and maintenance services for period of 10 years.

FSTP is the collection, transport, and treatment of faecal sludge from pit latrines, septic tanks or other onsite sanitation systems. Faecal sludge is a mixture of human excreta, water and solid wastes that are disposed in pits, tanks or vaults of onsite sanitation systems. FSTP is a sustainable technological solution developed by us to manage faecal sludge effectively. FSTP is Anaerobic and Natural process.

FSTP is necessary in densely populated areas where a proportion of the population is not connected to a sewerage network, and the covering and rebuilding pit latrines is not possible.
