Deep Aquifers

The presentation by ACWADAM is part of the training module developed by them on “Planning, development and management of groundwater with special reference to watershed management programmes”. Pumping a well and observing the effect of such pumping on the water level in the pumped well as well as in the adjoining parts of the aquifer through observation wells is the basic procedure involved in a pumping test.

The paper generated under the Challenge Program for Water and Food (CPWF) project explores in some depth a totally different dynamic in the irrigation economy of the vast Indo-Gangetic basin (IGB), an important exception to the global characterization. The global debate on ‘‘water as an economic good’’ presumes that irrigation water supply is delivered, controlled, and priced by public institutions. In the developing world, the price of water is kept so low that water use cost leaves farmers no incentive to use it efficiently. 

The paper by the Challenge Programme on Water and Food (CPWF) - Basin Focal Project provides a brief situation analysis related to water, agriculture & poverty, water resources, water productivity, institutional aspects and opportunities & risks related to the development of the Indo-Gangetic basin (IGB). Management of IGB water resources presents some formidable challenges and, therefore, steps must be taken towards integrated management of the IGB’s water and land resources in order to ensure the future sustainability of all production and ecosystems in the basin. 

This paper by the Institute of Social and Economic Change (ISEC) examines the extent of groundwater dependency and quality status in four South Indian cities viz., Hubli, Dharwad, Belgaum and Kolar cities. Widespread water shortage problems have resulted in increased dependency on groundwater with tapping the resources to unsustainable levels. In Karnataka, out of 208 urban local bodies that come under Karnataka Urban Water Supply and Drainage Board, 41 depend on groundwater.

WIO Urges the Government of Orissa to come out with a While Paper on state and availability status of water resources in the state. The demand comes in the wake of the government's consistent claim that the state is water surplus even though water scarcity hits us all every day.

Sambalpur, 5th August 2010 -  As the industrial overdrive of Orissa continues with signing of MoU after MoU with water guzzling industries, there is no clarity on the exact water available in the state.  The government has been propagating that Orissa is a water surplus state. However, statistics used by the various reports of the government are dated to 2001, from when the real industrialization boom has taken off in the state.  It is time that the government comes out with a transparent position paper on the exact water availability in the state or else water conflicts will aggravate.

Floods: lessons to be learnt from the massive flooding in Surat city

A report by IIM criticises the way in which dams are managed in the country and calls for the need to apply Management Science / Operations Research techniques and information technology to improve dam management and prevention of floods

Flood fury: are we ready to face such an event?

The report by Carewater INREM Foundation deals with groundwater and well water quality in the alluvial aquifers of Central Gujarat. Gujarat has a hydrogeology representative of almost all aquifer types and depositional & formation eras. Contamination of aquifers along with scarcity of groundwater resources due to increase in water demand and reduction in recharge of groundwater from changing landuse, is a problem in Central Gujarat.

This paper by Centre for Studies in Social Sciences and Jadavpur University, aims at explaining the factors that determine private investment in groundwater irrigation in West Bengal. It also addresses the issues pertaining to institutional arrangements, particularly provision of facilities by the government. The study, largely empirical in nature, is based on data collected from surveys conducted in close to one thousand moujas (villages) spread across the major agro-climatic zones in West Bengal. It begins with a descriptive account of the changes in the agricultural scenario in West Bengal over the last thirty years. The research questions are discussed and the econometric methodology presented.

The report deals with groundwater table and hydrochemistry of the Kakinada coastal aquifer in East Godavari, Andhra Pradesh.

My house is about 20 years old and is located in R T Nagar in Bangalore. In 1990, I had got a borewell dug. The Borewell is about 150 feet deep and has been giving me excellent quality water until about 2 years ago when I started noticing muddy water. The water that is pumped to an overhead tank contains fine particles of mud which tends to settle down in the overhead tank.
