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).
