International Rainwater Catchment Systems Conference
Mannheim, Germany - September 2001
Rainwater Catchment in Humid and Arid Regions
Rainwater Harvesting Techniques for Rural Houses
Kiteto District Arusha region is one of the semi - arid and arid areas
in Tanzania. WaterAid (UK, NGO)Tanzania, Kiteto programme has been working
in this area since 1997 to improve rural water supply, hygiene promotion
and sanitation. WaterAid Kiteto programme is working together with local
NGO known KINNAPA and Kiteto District Council (KDC) under tripartite partnership.
Currently, this WaterAid /KINNAPA /KDC programme is implementing six
borehole schemes. The big challenge that the programme faces is to locate
the borehole sites. According to the hydrogeological studies it was noted
that water is found in fault and not in sand aquifers which is very difficult
to locate them. Also their recharge is minimal due to little amount of
rainfall in a year (400mm - 600mm). Even the cost is high compared to
the rural communities' income especially, when considering the issue of
operation and maintenance costs.
Therefore the programme started to opt to other alternative technologies
for water sources such as improvement of traditional wells and harvesting
rainwater. The rainwater harvesting technologies include sand dams, small
dams, underground tanks and roof catchment for domestic uses. Responding
to this it is planned to conduct training to the mobilization team regarding
the rainwater harvesting technologies. Thus the paper wrote by the Project
Engineer WaterAid Kiteto is aimed to build the capacity of the TUWI team
to disseminate Rainwater harvesting technologies particularly for roof
catchment (starting with Ndaleta village).
