This CGWB report presents the over-all scenario of ground water resource utilization and availability of the country.

This document prepared by CGWB consists of standard designs to adopt roof top rainwater harvesting in Delhi.

The present `Master Plan for Artificial Recharge of Ground Water’ is an effort to assess the total recharge potential available in the country along with suitable designs of structures for such recharge.

Monitoring of ground water regime is an effort to obtain information on ground water levels and chemical quality through representative sampling. The important attributes of ground water regime monitoring are ground water level, ground water quality and temperature.

Ground Water Year Book is based on the information generated by monitoring of ground water observation wells of NCT-Delhi during the field Season of 2011-12.

Ground water utilization has increased significantly during the last two decades. The unplanned and indiscriminate use of this vital resource has resulted in declining water levels and water quality deterioration in certain areas.

This Atlas on Aquifer Systems of India compiled by Central Ground Water Board under the Union Ministry of Water Resources consists of detailed data on 14 principal and 42 major aquifers in graphical format through tables and maps.

Ground water levels are being measured four times a year during January, April/ May, August and November. The regime monitoring started in the year 1969 by Central Ground Water Board. At present a network of 14966 observation wells located all over the country is being monitored.
