Phase II of the project comprised of the Nairobi Dam Initiative which focused on a section of the river basin upstream of Nairobi Dam on the Motoine / Ngong River .

Six Project component were implemented with the main aims of showing the value of proper sanitation and waste management practices, demonstrating the utility of wetlands systems in improving the quality of impacted water systems , and promoting community involvement in safeguarding and monitoring the river basin as a vital resource.

1. A pilot project was implemented in a community (1,200 households) upstream of the Nairobi Dam to put in place proper sanitation and waste management practices to reduce its negative impact on the rivers. This phase constituted the implementation stage of the reccommended intervention strategies derived from Phase I .

2. and 3. Application of constructed wetland management techniques in two areas:
» The first site at the inflow of the Nairobi Dam (west) was critical in improving the quality of the surface waters entering the Dam.
» The second site at the Kenya Wildlife Service (KWS) headquarters (southwest of Nairobi) was designed to recycle 50,000 litres per day through constructing a wetland area which will reduce ground water depletion in the Nairobi National Park. Both these sites are open to the public.

4. The pollution-monitoring and data collecting network created during the first phase of the project was modified to focus on providing sufficient information for the assessment of the impact of the pilot project upstream, the constructed wetland at the Nairobi Dam, the water hyacinth purification ponds and the identification of major point sources of pollution.

5. Water hyacinth purification ponds were constructed to demonstrate good management of this invasive species and its use in purification of polluted water systems. Indigeneous expertise was developed for the use of the water hyacinth as a natural raw material in the production of high-quality household products and paper, thereby creating income generating activities for the neighbouring communities.

6. An intensive public information, education and awareness campaign is underway in co-operation with Habitat's Managing Water for African Cities programme (MWAC).
