The Water Research and Resource Center (WARREC) is leading a project on Participatory Assessment and Promotion of Fog Harvesting for Drinking Water in the Ngong Hills. This is a collaborative project with partners who include the Kenya Meteorological Department (KMD) the Pastoralists Organization for Water and Environmental Research (POWER), an NGO based at Kiserian, and Ped-World, a German NGO. This innovation was funded by JKUAT. The research findings show that fog harvesting is viable in the area, and the equipment collects both fog and rainwater very well!
On 1st August 2014, the Center organized the handing -over Ceremony of the Fog collector equipment to Ilmasin Primary school an event which was preside over by the Chancellor of JKUAT represented by the Vice Chancellor Prof. Mabel Imbuga.
The research has shown that a typical fog collector can harvest about 80 to 1,000 litres per day, depending on the net size, mesh/fibre design, fog density and wind. The fog collectors currently installed in the Ngong hills are of two sizes. Each 20 sq.m net at Ilmasin and Olteyani can collect 1,500litres/day if it rains. A 40 sq.m fog collect is at Ilmasin primary school (Plate 1).
