Construction, operations and maintenance
De-silting will most probably need to be carried out at some stage. There may be more sustainable ways of doing this compared to the usual approach used in the recovery stage of DCM, where this process is often paid for by NGOs and where there is a lack of community will to contribute. Experience from infiltration ponds in India shows that securing participation is very difficult to achieve when users/farmers do not see any direct benefit from the ponds. An institutionally-resilient way to de-silt (or even construct) ponds may be to promote ponds on private land, where one landowner has a vested interest to maintain and de-silt the pond, thus reducing the need for NGO intervention in the longer run. Experience in India seems to support this where the farmer providing the land for the johad (pond) would be the prime beneficiary, of the recharged water on adjacent land, but where the community also benefited.
 
Pond depth should be deep enough to prevent excessive algae and water plant growth, but not too deep so that anaerobic conditions are avoided – this means a depth of between 1-4 metres.
