rain water harvesting
Water is nectar of life and life cannot sustain without it. Ever increasing demands of water for domestic, irrigation as well as industrial sectors have created water crisis worldwide. Ground water is the only dependable source of water. Inferior quality of groundwater with high salinity, fluoride and nitrate contents further limits the availability of fresh water assets.
Depleting groundwater resources, water logging hazards, deep water levels, higher degree of salinity, high fluoride and nitrate concentration, industrial pollution etc. are the main ground water related areas of concern which needs appropriate attention of management for Rain Water Harvesting & Artificial Recharging.
WHY RAIN WATER HARVESTING?
Ground water plays a critical role in the urban environment. It has a significant contribution in municipal, industrial and domestic water supply. Urbanization strongly affects ground water recharge flow and quality thereby creating serious impact on urban infrastructure that may lead to socio – economic and environmental degradation of the area. As urban dwellings go on increasing shrinkage of open land leads to continuous
decline in ground water levels in many areas.
It has therefore; become imperative to promote rain water harvesting and artificial recharge to augment ground water recharge.
Rain water harvesting is essential because :-
Û Surface water is adequate to meet our demand and we have to depend on ground water.
Û Due to rapid urbanization infiltration of rain water into the sub – soil has decreased drastically and recharging of ground water has diminished.
Û Over – exploitation of ground water resources has resulted in declined in water levels in most part of the country.
Û To enhance availability of ground water at specific place and time.
Û To arrest sea water ingress.
Û To improve the water quality in aquifers.
Û To improve the vegetation cover.
Û To raise the water levels in wells & bore wells that are drying up.
Û To reduce power consumption.
BENEFITS OF RAIN WATER HARVESTING
Û An ideal solution of water problem in areas having inadequate water resources.
Û The ground water level will rise.
Û Mitigates the effect of drought & achieves drought proofing.
Û Reduces the runoff which chokes the storm water drains.
Û Flooding of roads is reduced.
Û Quality of water improves.
Û Soil erosion will be reduced.
Û Saving of energy per well for lifting of ground water – one meter
