UDDTs and greywater treatment at Secondary School, Nakuru, Kenya
Crater View Secondary School. Case study of SuSanA

This SuSanA case study compiles experiences from a ROSA sanitation pilot project implemented in a secondary school in Nakuru, Kenya. Single vault urine diversion toilets, a faeces drying shed and greywater treatment were implemented in this project. The project serves about 200 students.

The toilet block has a separate girls and boys section with waterless urinals. The female urinals are a quite unique installation in Kenya. Urine is collected in a large masonry underground tank and the faecal material fully dried in a roofed shed. The greywater is treated in a constructed wetland with vertifer grass. The treated greywater, urine and dried faeces are supposed to be used for raising trees at a small school farm. The facilities were monitored and evaluated after about 3 years of operation showing some challenges with the reuse of faecal material after drying. A follow up saniation program called CLARA will address the challenges witnessed in this peri-urban area.
