This paper examines the possibilities and challenges of
rainwater harvesting in both rural and urban areas of Kenya. The problems of
water shortage in urban areas and the high costs of developing new surface
water sources, the scarcity of ground water supplies in Arid and Semiarid Lands
(ASALs) and the unmanageable operation and maintenance costs of large piped
water supplies are alarming. Therefore the willingness of the people,
particularly in arid and semiarid areas, to embrace low cost initiatives like
rainwater harvesting. The solutions suggested emanate from the grassroots community
projects, the authors experiences in the water sector as an engineer and
recommendation from household rainwater harvesting workshops
