Description of the SLM Technology
Short description of the Technology
The roof top rain water harvesting system using a concrete tank was designed to improve household access to water for irrigation of kitchen garden plots during the hot and dry summer months.
Detailed description of the Technology
A 16 cubic metre concrete tank situated in the shadow of the house constructed to retain rainwater that collects in the roof guttering.
Purpose of the Technology: The purpose of the tank is to retain water to be used for drinking, sanitation and irrigation during the hot and dry summer months. The retained water allows for the irrigation of kitchen garden plots and more diverse crops, and hence should improve the livelihoods of households involved.
Establishment / maintenance activities and inputs: There are three main elements to the construction of the rainwater harvesting system. The first is the construction of a metal gutter on wooden supports around the perimeter of the roof; second, the construction of a concrete pool in the shadow of the house; and finally the provision of a connection pipe between the gutter and the pool. The pool needs to be cleaned periodically to prevent contamination and build up of algae around the edge the pool.
Natural / human environment: During the Soviet period the water supply for the village was supplied through a concrete storage tank located at the foot of the hills above the village. After the collapse of the Soviet Union the concrete tank and its associated infrastructure fell into disrepair. As a result the inhabitants were faced with water shortages, especially during the hot dry summers. In response to this issue the residents invested time, finance and resources into constructing rainwater collection systems.
