NYEWASCO is in the initial stages of implementing the Upscaling Basic Sanitation for the Urban Poor (UBSUP) programme, which is a country-wide up-scaling intervention aimed at providing access to basic household sanitation in urban low income areas of Kenya. UBSUP is anchored at the Water Sector Trust Fund with technical support from GIZ and funding from the Bill and Melinda Gates Foundation and the German Government through the German Development Bank (KfW).

The programme is implemented by licensed Water Services Providers (WSP/utilities) and covers the entire sanitation service chain. UBSUP undertakes the scaling up of the following activities: promotion of improved toilets at household level, involvement of the private sector to provide emptying and transport services where applicable and implementation of Decentralised Treatment Facilities (DTF) to offer treatment and safe disposal of the faecal sludge. UBSUP aims to provide sustainable sanitation for at least 400,000 people. Public sentimentalization is currently ongoing in the Witemere area which aims at identification of customers who are in dire need of toilet upgrade from the common pit latrine to flush toilets that will be connected to the sewer line. This will largely improve sanitation status in the LIA and help curb diseases.
