The Use Of Low-Cost,
Self-Help Rain Water Harvesting Systems For Community Water Supply In Southern
D. Lee & Erick Nissen-Petersen
The Mutomo Soil and Water Conservation Project has helped implement a wide
range of water harvesting systems for the improvement of community water supply
in the semi-arid Southern Division of Kitui District, Eastern Province, Kenya.
Several rain water cistern systems have been developed which harvest runoff
water from rooftops, roads, compounds, springs and exposed bedrock. These compliment
larger communal runoff water harvesting systems such as rock catchment
dams, earth dams and shallow well/sub-surface dams. They are low-cost, appropriate
technologies involving a high-level of community participation in planning, construction
and maintenance. Artisans selected from the local community and trained and equipped
by the project have combined with women's and other selfhelp groups to install
rain water tanks at most schools and public buildings in the Division.
The paper focuses on the approach adopted by the project in implementing rain
water harvesting systems in a marginal, rural, semi-arid area wiih a predominantly
subsistence economy. Some general recommendations and
conclusions are summarised from the experiences at Mutomo from 1982-1987 and
the five standard tank designs adopted by the project and ranging from a seven
cubicmetre tank system costing US $157-168, to an 78 cubic metre excavated tank
costing US $690-870 inclusive are described.
