Feedstock Adequacy for a 2-Engine J-OP in One Indian City: Findings from a Multifunctional Study in Tiruppur, India

Apr 30, 2019

Prior to designing and installing a fecal sludge treatment system (whether an Omni Processor [OP] or a fecal sludge treatment plant [FSTP]), it is important to gain an understanding of your fecal sludge management (FSM) reliant population, including the volumes of FS and mass of dry solids they generate. STeP, along with local partner Athena Infonomics, conducted a 3-part study between November 2017 and March 2018 to better understand the FSM reliant population residing within a 20 km radius of a potential OP site in Tiruppur, Tamil Nadu. The study aimed to (a) understand household characteristics and FSM behaviors; (b) quantify the volume of FS generated in the 20-km catchment area; and (c) evaluate the energetic properties and total solids content of the FS collected in Tiruppur. Based on measured FS accumulation, total solids and energetic value, there is close to sufficient feedstock to supply a 2-engine J-OP within a 20 km radius of the proposed site in Tiruppur, equating to a fecal sludge management (FSM) population of approximately 1 million people.

Key topics:

  • Fecal sludge accumulation and volume
  • Household characteristics and FSM behavior
  • Calorific value and total solids (TS) content of FS
  • Optimal size J-OP
