Re: Key documents for Category 1 "Design and Technologies" (Decentralised Treatment Facilities)

Examples of Decentralised Treatment Facility (DTF) in Kenya with the UBSUP (Up-scaling Basic Sanitation for Urban Poor) project implemented by GIZ and WSTF (see SuSanA forum post here )

Nakuru DTF that comprises of: a Receiving Bay / Balancing tank (RBBT), a biodigester/expansion chamber and a Anaerobic Baffled Reactor (ABR).

To be noted, the DTF in Nakuru was part of the pilot phase of the UBSUP project and therefore is quite different from the design currently implemented. The DTF being located within a conventional waste water treatement site, the treated effluent from the ABR is discharged into a treatment pond. For that reason the DTF doesn't include any tertiary treatment module.
