 Urban Ground Water Management Top
The Board has taken up urban ground water management studies in some major cities of the Maharashtra State. Under these studies, the status of ground water development and also the status of water supply to the urban area are being studied and data is being collected from various sources to see the impact of rapid urbanization and industrialization and the exploding population on the existing source of water supply and ground water flow regime. Till March 2003, these studies have been taken up in the following urban areas:
  i)  Urban Hydrgeology and Impact of Population on Ground Water Regime in Osmanabad Municiple Corporation Area, Osamanabvad District, S.K.Banasal, Sc - D, 2000-2001  
  ii) Impact of Urbanization on Groundwater Regime in Solapur City Maharashtra, Dr. P.K.Naik, Scientist- D, 2002-2003  
  iii)Urban Hydrgeology and Impact of Population on Ground Water Regime in Aurangabad City, Aurangabad District, S.K.Jain, Sc -C, 2000-2001  
  iv)Urban Hydrgeology and Impact of Population on Ground Water Regime in Nanded- Waghala Area, Nanded District, Pandith Madhnure, Assistant hydrgeologist, 2001-2002  
  v)The parameters considered for evaluation are: a) Specific Capacity b) Wire to Water Ratio c) change in chemical quality of ground water. The final report is under preparation.  
Remote Sensing Studies Top
  Remote Sensing studies were carried out for various activities of the region using Aerial Photographs, Imageries (both Landsat and IRS) and GIS techniques. The major works taken up under these studies are:  
  i) Trap - Alluvium boundary of Tapi and Purna alluvial basin was demarcated in Amravati, Akola, Buldhana, Jalgaon & Dhule district based on Aerial photo studies.  
  ii) Hydrogeomorphic and lineament maps were prepared based on aerial photo and imagery studies for incorporating in district, systematic/ reappraisal hydrogeological survey reports.  
  iii) Lineament sites were selected for ground water exploration, which proved to be high yielding wells. Similarly, lineament maps were prepared for drought relief work for Bhandara, Wardha and Raigarh districts.  
  iv) Studies were carried out in Ramtek taluka, Nagpur district and in Barshi area in Sholapur district.

Assistance To Government Of Maharashtra  
The CGWB, Nagpur is providing technical assistance to the Maharashtra Government for ground water development and management from time to time which are mentioned as under.
Drought Assistance  
Under drought relief assistance in 1987 and in subsequent years, the Board has surveyed 919 drought affected villages in Pune, Ahmadnagar, Bhandara, Gadchiroli and Yavatmal districts of Maharashtra and suitable sites were recommended for rural water supply. The Board had also assisted in construction of 21 Deposit wells in all, with 12 in Chandrapur and 9 in Dhule districts.
Technology Mission  
  Under the Rajiv Gandhi National Drinking Water Mission, the Board had surveyed 234 villages in Satara, Latur and Nagpur districts for Source Finding to cater to the needs of drinking water requirements of problematic villages.  
Source Finding & Exploration in Scarcity Villages in Raigad District  
The Hon'ble Minister for Water Resources, Shri. A.R. Antulay has advised the Director, C.R. in 1995 to take up immediate appropriate steps to mitigate tha acute shortage of drinking water problems in scarcity affected villages in Raigad district where the water supply is met through tankers. Based on this reust, the Central Region has carried out Source Finding in 21 villages covering Pen, Khalapur and Uran talukas and made suitable recommendations for rural water supply. The Region has also construced exploratory wells at Dolavali Anjurun in Khalapur taluka and Gagode Khurd in Pen taluka and handed over to the State Govt. for rural water supply.
Design Of Irrigation Tube Wells Propsed To Be Constructed By The State Govt. Under Ganga Kalyan Yojana  
Under Ganga Kalyan Yojana, the Ground Water Survey & Development Agency (GSDA), Govt. of Maharashtra had submitted a proposal for the feasibility of construction of additional irrigation tube wells in alluvial/Gondwana formations in 8 districts of Maharashtra. The observation of CGWB and the preparation of model design for tube wells were made available to the GSDA. The CGWB had indicated unfavourable areas and also expressed its reservations in the construction of TW in Dhule and Jalgaon districts where excessive ground water development was noticed.
Feasibility of Tube Well Irrigation Scheme  
The State Govt. had submitted a scheme for tube well irrigation in alluvial tract of Purna and Tapi and also for Gondwana Formations. The scheme was refereed to CGWB for technical feasibility. The Scheme was scrutinized and comments were forwarded to reduce the number of tube wells and also not to construct tube wells in Dark and Grey areas.
Earthquake-hit areas  
The Board has taken up intensive ground water studies aided by drilling in Earth Quake affected areas of Latur and Osmanabad districts of Maharashtra during 1993 and also served the Kutch area of Gujarat after the earth quake of 2001 for rehabilitation of affected villages and provided drinking water needs through construction of bore wells.
Water Supply Investigation to Defence establishments  
The Board also provides its services to various Defence establishments to over come the water shortage problems through Short-Term Water Supply Investigations. Assistance is also provided in ground water management activities involving artificial recharge to ground water and roof-top rain water harvesting.
Asistances to Other Agencies  
The Ministry of Environment and Forests has made a special request to assess the effect of proposed Ash Ponds to be constructed by M/s. Nippon Dendro Ispat Ltd for 1000 MW Thermal Power Project near Bhadrawati, Chandrapur district in order to dispose the ash generated from this power plant. In order to study the suitability of the proposed Ash Pond area from ground water and environmental angle for ash disposal, a joint team with representatives of CGWB, Nagpur visited the site. It was opined that the proposed ash ponds are to be lined to prevent possible contamination of surface and ground water bodies. It was also felt desirable to establish observation wells to periodically monitor the water level and chemical quality of ground water from hallow and deeper aquifers. A joint report incorporating the above was prepared and submitted.
