DESIGN CONSIDERATIONS:
The important aspects to be looked into for designing a rainwater harvesting
system to augment ground water resources are: -
? Hydrogeology of the area including nature and extent of aquifer, soil cover, topography, depth to water level and chemical quality of ground water.
? The availability of source water, one of the prime requisite for ground water recharge, basically assessed in terms of non-committed surplus monsoon runoff.
? Area contributing run off like area available, land use pattern, industrial,
residential, green belt, paved areas, roof top area etc.
? Hydrometerological characters like rainfall duration, general pattern and
intensity of rainfall.
POTENTIAL AREAS
? Where ground water levels are declining on regular basis.
? Where substantial amount of aquifer has been de-saturated.
? Where availability of ground water is inadequate in lean months.
? Where due to rapid urbanization, infiltration of rain water into subsoil has decreased drastically and recharging of ground water has diminished.
