Groundwater, though replenishable, is ultimately a finite resource. Excessive withdrawal leads to depletion of the water stored underground, resulting in serious social, economical and environmental consequences.
Water for cities - Responding to the urban challenge – Technical papers from the Third National Groundwater Congress by CGWBposted 9 years ago
Deliberations in the Congress organized by the Central Ground Water Board (CGWB) at New Delhi on March 22-23, 2011 focused on various issues viz., Integrated Water Resource Management, Artificial Recharge to Groundwater, Water Use
The Central Ground Water Board (CGWB) under the Ministry of Water Resources has released a publication entitled “Aquifer systems of India” apart from aquifer atlas for six states viz. Kerala, Tamil Nadu, Karnataka, Chhattisgarh, Himachal Pradesh and Meghalaya.
Groundwater scenario of India - A report by Central Ground Water Board, Ministry of Water Resources (2009-10)posted 9 years 5 months ago
This document by Central Ground Water Board (CGWB) sheds light on ground water scenario of India for the year 2009-10. The major issues discussed in the document are categorised under three broad sections:
It also presents the status of utilisation of groundwater in Karnataka as on March 2009, both on watershed (sub catchment) and taluk wise areas having 2008-2009 as the base year. The methodology is improved as the estimations are carried out on watershed basis for both command and non command separately than apportioned to taluks.

The CGWB under the Ministry of Water Resources, Government of India, is the national apex agency entrusted with the responsibilities of providing scientific inputs for management, exploration, monitoring, assessment, augmentation and regulation of ground water resources of the country.
Case studies on rainwater harvesting and artificial recharge – A compilation by Central Ground Water Boardposted 10 years 6 months ago
Groundwater caters to the demand of ever growing domestic, agricultural and industrial sector of the country and is being indiscriminately exploited by several users. On the other hand, rapid urbanization and land use changes has resulted in reduced natural infiltration or recharge of aquifers.
This has led to various problems related to quantity and quality and issues like the decline in water levels, depletion of groundwater resource and quality deterioration. There is thus an imperative need for augmenting the valuable groundwater resource. Artificial recharge and roof top rainwater harvesting is one such method that can revive this precious resource. Several traditional and scientifically proven artificial recharge and rainwater harvesting techniques have been adopted in different parts of the country. These structures have proven to be viable option for augmenting the groundwater aquifers by making use of surplus surface runoff.
It covers varying groundwater scenarios in the country including the highly developed metros, the hilly region, the coastal cities, the cities tapping unconsolidated and hard rock aquifers. The report briefly describes the administrative set up, status of water supply and demand, groundwater scenario, feasibility of rainwater harvesting and groundwater development strategy.
It is an updated version of an earlier report on “Groundwater in urban environment in India” (2000). Since then, groundwater regime, urban demography and water demand have changed enormously. This report will form a scientific base for an in-depth understanding of urban groundwater system including aquifer geometry, water level behavior and groundwater quality. The possibility of artificial recharge to rejuvenate the urban aquifers has also been discussed.
Groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district – A study by Central Ground Water Board and Aligarh Muslim Universityposted 10 years 10 months ago
This report by Aligarh Muslim University and Central Ground Water Board (CGWB) deals with groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district. For evaluation of the groundwater resources and for minimizing the error of estimation, the system has been evaluated through aquifer modelling where water balance is established using partial differential equation of groundwater flow and is solved with boundary and initial boundary conditions.
Dug well recharge scheme (2007-08 to 2009-10) - Revised guidelines with amendments to the scheme by the Central Ground Water Boardposted 11 years 8 months ago
The State sector scheme on artificial recharge to groundwater through dug-wells is under implementation over the first three years of the (current) XI Plan Period (2007-12), in 1180 over-exploited, critical and semi-critical blocks/ talukas/ mandals in seven states of the hard-rock peninsular region of India, namely Andhra Pradesh, Maharashtra, Karnataka, Rajasthan, Tamil Nadu, Gujarat and Madhya Pradesh. The target beneficiary of the scheme are farmers who have privately owned wells, in their agricultural land.
