Rain Water Harvesting for Artificial Recharge

Artificial recharge is the planned, human activity of augmenting the amount of groundwater available through works designed to increase the natural replenishment or percolation of surface waters into the groundwater aquifers, resulting in a corresponding increase in the amount of groundwater available for abstraction. Although the primary objective of this technology is to preserve or enhance groundwater resources, artificial recharge has been used for many other beneficial purposes. Some of these purposes include conservation or disposal of floodwaters, control of saltwater intrusion, storage of water to reduce pumping and piping costs,temporary regulation of groundwater abstraction, and water quality improvement by removal of suspended solids by filtration through the ground or by dilution by mixing with naturally-occurring groundwaters (Asano, 1985). Artificial recharge also has application in wastewater disposal, waste treatment, secondary oil recovery, prevention of land subsidence, storage of freshwater within saline aquifers. Groundwater recharge methods are suitable for use in areas where aquifers exist. Typically, unconfined aquifers are recharged by surface injection methods, whereas confined aquifers are generally recharged through subsurface injection. Surface injection methods require relatively flat or gently sloping lands, while topography has little effect on subsurface recharge methods. Aquifers best suited for artificial recharge are those which can absorb and retain large quantities of water. In temperate humid climates, the alluvial areas which are best suited to artificial recharge are areas of ancient alluvium, the buried fossil river-beds and interlinked alluvial fans of their main valley and tributaries. In the arid zone, recent river alluvium may be more favourable than in humid zones. In these areas, the water table is subject to pronounced natural fluctuations. Surface recharge methods are best suited to these cases. Coastal dunes and deltaic areas are also often very favourable areas for artificial recharge schemes. Dense urban and industrial concentrations in such areas may render artificial recharge schemes desirable, generally using subsurface recharge wells to inject surface water into the aquifers. Advantages As surface water augmentation methods, such as dams and diversions, have become more expensive and less promising in terms of environmental considerations, the prospects of storing surplus surface water underground and abstracting it whenever and wherever necessary appears to be more effective technology. In urban areas, artificial recharge can maintain groundwater levels in situations where natural recharge has become severely reduced.

Ground Water Management Services

Groundwater is becoming an increasingly popular resource because of the relative ease and flexibility with which it can be tapped. While developing groundwater resource promises to help alleviate poverty in many areas, the most formidable challenge is its sustainable use and management in regions where it is under threat.

The economies that groundwater generates the socio-economic impact of its intensive use, and the physical, institutional and policy options for its management. The book provides a fresh analysis of the socio-ecology of groundwater, based on a synthesis of macro and micro level data on the hydrological, social, economic and institutional parameters. The region of North Gujarat has been specifically studied to document the uncontrolled use of groundwater and the ill-effects of such exploitation. With alarming drops in water levels and increasing levels of fluorides and TDS in groundwater, the region's water problems have attracted international attention because of their implications in terms of reducing the viability of irrigated agriculture as also their impact on community health. The findings are used to draw policy conclusions regarding the tools for managing groundwater in other regions with similar resource and use characteristics. The authors have used several new methodologies, analytical procedures and criteria to analyse groundwater use in agriculture, the economic value of groundwater, water intensity of milk production and the efficient use of groundwater.
