A water resource development study was carried out on a limestone mining area located in the Madukkarai block of Coimbatore district in Tamil Nadu state in India. The study covers the assessment of water resources for the present and future, water balance status and formulation of a management and conservation strategy for the area. Madukkarai block was considered as an influencing zone, which extends over an area of 249.16 km2. There is no perennial river in the study area and the annual average rainfall is only 590 mm. The groundwater is generally potable. Annual utilizable groundwater resource available in the area is 41.50 million m3 (Mm3) and the present annual groundwater requirement is 38.44 Mm3, whereas the annual requirement for various uses in the year 2010 and 2020 would be around 41.62 and 45.07 Mm3, respectively. This problem of water scarcity in the region has to be mitigated by immediate initiation of suitable short- and long-term water supply augmentation strategies for enhancing the groundwater recharge. To reduce the heavy surface runoff loss and enhance the groundwater recharge capacity of the area, suitable water retaining structures should be constructed. The recharge zones and recharging techniques are identified for artificial recharge of aquifers. Inter-basin transfer of water is also required to artificially recharge the aquifers for augmentation of the groundwater potential of the area so as to meet the future needs.
