YEP period 2019 - 2021, batch 18

Young Expert at Practica Foundation - Madagascar

First position after YEP

Fecal Sludge Management Technician at Practica Foundation, Madagascar

YEP Role

During my YEP employment, I will support the development of a pro-poor latrine emptying service which will integrate two innovations with Practica foundation. First, the service will be delivered by a tractor with two different trailers (slurry tanker, simple trailers) in order to access all parts of the city (which is characterised by a hilly landscape). Secondly, service costs will be partially covered by the benefits generated from public toilets in order to improve service affordability for poor people.


My main tasks include: 

  • Develop and set-up Standard of Procedures (SOPs) for the emptying services. Adapted from previous SOPs developed by Practica in Zambia, these SOPs will describe all details related to transport, opening, desludging, dumping, treatment and cleaning operations involved within the FSM chain. From a draft version these SOPs will be improved by practice, and related training and monitoring tools will also be developed;
  • Design, model and monitor O&M costs of the FSM service including the subsidy component from public toilets. Using excel, and templates developed by Practica within other projects, I will compile all required field data (labour efficiency, fuel efficiency, etc…) to allow the financial analysis and set affordable tariffs for poor households while keeping the FSM service profitable;
  • Train and coach the FSM service partners in performing high quality services from the pit emptying to the management of treated sludge;
  • I will attend practical trainings given by Practica senior trainers to the service provider, and will coach the workers downstream, ensuring the link between experts and workers until the service reaches an acceptable yield of activity and level of quality.
