Managing waters in India’s varied ecological zones
Published: Aug 15, 2018
Abstract: It is IRONIC that the Himalaya, often alluded to as the ‘water tower of Asia’—the source of mighty rivers that support millions, now face stress especially during summers. The rapidly reducing flow in surface drainage and the disappearance of springs are signs of looming disaster.

Non-revenue water is the water that has been produced but is lost before it reaches the customer. It is one of the biggest problems as it increases the water stress.
An aquifer is an underground layer of permeable rock, sediment, or soil that yields water. The aquifers near the surface are usually used for water supply and irrigation.
Drip irrigation is a micro-irrigation system where water drips slowly into the roots of the plants from pipes buried below the surface.
Groundwater recharge is a hydrologic process where water moves downwards from surface water to groundwater. Groundwater recharge occurs through wetlands, rainfall and more.
A floodplain is a strip of relatively flat and normally dry land alongside a stream, river, or lake that is covered by water during a flood. Floodplains are produced by lateral movement of a stream and by overbank deposition.
Hardness of water is the quality indication of salts in water. Water hardness can cause costly industrial problems, such as breakdowns in boilers and cooling towers, and may even cause irreplaceable corrosion. The temporary hardness of water can be removed by boiling, while permanent hardness removal require a water softener or an ion exchange column.
A settling pond is an open lagoon into which wastewater contaminated with solid pollutants is placed and allowed to stand. The basins are used to control water pollution in industries such as agriculture,aquaculture, and mining.
