Abstract:

Water is precious and fast becoming a scarce natural resource which is required to be conserved, augmented and harvested by applying suitable conventional as well as innovative techniques. Water harvesting is a technique of developing surface water resources that can be used in dry regions to provide water for livestock, for domestic use, and for agro forestry and small scale subsistence farming. Water harvesting systems may be defined as artificial methods whereby precipitation can be collected and stored until it is beneficially used. The system includes: 1) a catchment area, usually prepared in some manner to improve run off efficiency and 2) a storage facility for the harvested water, unless the water is to be immediately concentrated in the soil profile of a smaller area for growing drought-hardy plants. A water distribution scheme is also required for the systems devoted to subsistence farming for irrigation during dry periods. Mining activities disturb groundwater aquifers. Underground mining disturbs deep aquifers whereas opencast mining disturbs both shallow and deep aquifers. In order to extract coal, large quantity of water accumulated at the pit bottom is required to be pumped out to the surface. Therefore coal mining areas are always subjected to acute water crisis unless suitable care is taken to ensure the proper water supply and in this context, rain water harvesting is one of the most appropriate technology to conserve the water management in the study area. With these concepts in the background, the present study has been carried out in context with the Chasnalla Group of Mines, ISP, SAIL.
