  • Dear Sir/Madam,

    Your site is giving very good information about water, It is very useful in our dailylife, Now a days due to lack of

    sufficient water so many persons are facing many problems. In this circumstances Borewells in Hyderabad is doing

    some help to dig and get water. Some of the Borewells in Hyderabad.

  12. 12. GSDA  Maharashtra – Only State having independent Govt GW Department  Machinery across State upto District Level  Governed by Water Supply & Sanitation Department  Funded through budgetary allocation
  13. 13. Groundwater Survey Work  Systematic Hydrogeological Survey of 25400 villages of the State  Delineated Groundwater Worthy and Non-Worthy Areas in these villages  Village level Gw Data base available for Development and Management
  14. 14. Groundwater Survey Work  Hydrogeological Survey for Drinking Water Sources in the State  Geophysical Survey for confirmation & potential area delineation  Hydrogeological Survey for GW development
  15. 15. Groundwater Level Monitoring Network  Long duration & Strong data base for groundwater levels  Research Work  Policy framing  Water Scarcity Declaration & Mitigation  Declaration of Over Exploited/Critical Watersheds
  16. 16. Water Scarcity Prediction Gw Levels of Oct 08 w.r.to last five years Avg Talukawise Actual Rainfall of 2008 w.r.to normal
  17. 17. Groundwater Quality Monitoring Network  Analysis of Chemical & Bacteriological Data  3370 Baseline, 397 Trend & 578 N W E Trend-cum-Surveillance S > 1500 mgl  Research Work 1200 - 1500 mgl 900 - 1200 mgl 600 - 900 mgl  Policy framing 300 - 600 mgl up to 300 mgl  Strategies for Preventive Measures  Declaration of water quality affected areas
