Construction, operations and maintenance
Further, the outlet and upstream riverbed should be cleaned regularly to make sure the dam does not get blocked. Silt, rocks, dead animals, etc. should be removed regularly. This can also help prevent contamination of the water. The quality of the water in the well should be checked, once in a while, by an expert.
 
In order to insure success at all stages of construction, operations and maintenance, the local community needs to be trained to manage and maintain the dam. Promote catchment-level planning & management so that varying groups have a vested interest in the same source. They can start to address
improvements in soil/water conservation, food production & health. Previous dam committees have shown that they tend to stop functioning effectively after the construction phase. By taking longer to build the dam, e.g. 3 stages over 3 years, it may give enough time for a catchment-based dam association to form & start functioning.
====Estimated Lifespan====
The lifespan depends on the materials used and expertise with which it is constructed and maintained. The dams in Kitui Kenya were built at a cost of 7500 USD and have a minimum lifespan of 50 years.
