2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Dugout pond is a sunken water harvesting structure constructed along the rills in upper catchment for the purpose of storage of runoff and recharge of ground water.
2.2 Detailed description of the Technology
Dugout pond is a rectangular shape subsurface pond with the excavated material forming an embankment down stream. It is constructed in the upper catchment of the watershed, along the rill/shallow gully. The site for the pond should be where there is a depression. The size may vary from small to large depending on the size of catchment, needs of the farmers, availability of finance, bed rock strata.
Purpose of the Technology: 1- Storage of runoff. 2- Increase in water levels of shallow wells 'odees' through increased percolation. 3- Flood control through series of such structures. 4- Low cost, low risk alternative for poor community. 5- Benefits to community living in upper catchment.
Establishment / maintenance activities and inputs: 1- Site selection with community. 2- Design and preparation of estimate by the project staff. 3- Descussion with VWDC and community, identification of users, descussion regarding contribution, agreement, work plan. 4- Layout and construction under VWDC supervision with technical support from the project. 5- Treatment of catchment.
Natural / human environment: Responsibility of user group.
