Faecal Sludge Treatment Plant

Faecal Sludge Treatment Plant

Faecal Sludge Treatment Plant (FSTP) is a vermifiltration based comprehensive and sustainable technological solution developed by us to manage faecal sludge effectively. FSTP can separate solid and liquid wastes to convert them into vermicompost and water for non-potable uses such as gardening, flushing and farming with appropriate treatment.

Faecal sludge management (FSM) is the collection, transport, and treatment of faecal sludge from pit latrines, septic tanks or other onsite sanitation systems. FSM is necessary in densely populated areas where a part of the population is not connected to a sewerage network, and the covering and rebuilding of pit latrines is not possible.

The Faecal Sludge Treatment Plant (FSTP) is based on the Tiger Bio Filter technology. It comprises of five main processes:

  • Screening
  • Anaerobic digestion
  • Vermifiltration-I – Residual solid and liquid separation
  • Vermifiltration-II – Wastewater treatment
  • Polishing – Tertiary treatment


In partnership with UNICEF, PriMove with the help of TBF Environmental Solutions Pvt. Ltd. has set up two FSTPs with a capacity to treat 10 Kilo litres of Faecal Sludge per day (10KLD/Day) each – one in Kalpetta Municipality in Wayanad district and the other in Thrissur Municipal Corporation in Thrissur district, both in Kerala. These projects are a part of rehabilitation measures initiated and organised by UNICEF after Kerala received severe floods in August 2018.
