GROUND WATER DEPARTMENT

THE DEVELOPMENTAL ACTIVITIES OF GROUND WATER DEPARTMENT-KHAMMAM DISTRICT

  • The main activities of the Department are to carryout Hydrogeological, Geophysical and Hydrological surveys to delineate potential zones of groundwater, including water logging areas and groundwater stressed areas for optimum usage.
  • Ground water surveys for selection of suitable sites for construction of different types of wells for Agriculture, drinking water, Govt. Departments and other usages under WALTA
  • Groundwater investigations in the lands of SC/ST farmers and also exploratory drilling of bore wells which were targeted in the annual action plan under Special Component special development fund/Tribal special development fund.
  • Conducting ground water investigations for selection of sites for construction of Percolation Tanks, Check Dams and Rainwater Harvesting Structures to recharge ground water.
  • Conducting environmental studies for Sand mining, Granite mining and industries of Public and private sectors and also carrying out groundwater pollution studies whenever called by the district administration.
  • According Groundwater clearance to industries through TS-ipass.
  • According technical clearance for infiltration (I.F.) wells for Irrigation and drinking water under Lift irrigation scheme
  • This department is taking up estimation of Groundwater Resources in the district at periodic intervals for scientific planning, development and management for its sustainability. Groundwater estimation is a key role in many programs being taken up by the government
  • Conducting awareness programs in over exploited areas, suggesting on effective utilization, conservation through artificial recharge structures and management.
