There are two types of aquifer recharge (AR): 1 - Natural recharge 2 - Artificial aquifer recharge. Natural recharge is precipitation, river bed seepage, flooding and other natural forms of water that enter the groundwater system. Artificial aquifer recharge is the enhancement of natural groundwater supplies using man-made conveyances such as infiltration basins, field flooding, infiltration galleries or injection wells. Often, AR is conducted to improve groundwater resources (i.e. increasing storage) and is often incorporated into a broader water resource plan Why to harvest rain? In areas where there is inadequate groundwater supply or surface resources are either lacking or insufficient, rainwater harvesting offers an ideal solution. Helps in utilising the primary source of water and prevent the runoff from going into sewer or storm drains, thereby reducing the load on treatment plants. Reduces urban flooding. Recharging water into the aquifers help in improving the quality of existing groundwater through dilution. Water conflicts Summer comes to India every year. Along with it comes water crisis As wells, ponds and taps dry up, women begin to walk the village streets and city roads with pots and pitchers looking for a water-point. As municipality water-tankers and government-run water trains begin to traverse the length and breadth of the country, people gather on street corners, village squares and in front of municipality offices. They murmur, growl, throw stones, and fight... Water is becoming a cause for social conflicts Protests, demonstrations, road-blockades, riots. City-dwellers against farmers. Villages against towns. Towns against cities. Citizens against the government. People against people. Increasingly, these (usually local) conflicts are taking on the general shape of a bitter war for water. Is there a way out? What should we do? Hang down our heads in shame? Or, should we look up? A rainwater harvesting system comprises components of various stages - transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse or recharge. The common components of a rainwater harvesting system involved in these stage Urban centres in India are facing an ironical situation today. On one hand there is the acute water scarcity and on the other, the streets are often flooded during the monsoons. This has led to serious problems with quality and quantity of groundwater. This is despite the fact that all these cities receive good rainfall. However, this rainfall occurs during short spells of high intensity. (Most of the rain falls in just 100 hours out of 8, 760 hours in a year). Because of such short duration of heavy rain, most of the rain falling on the surface tends to flow away rapidly leaving very little for recharge of groundwater. Most of the traditional water harvesting systems in cities have been neglected and fallen into disuse, worsening the urban water scenario. One of the solutions to the urban water crisis is rainwater harvesting - capturing the runoff. From now to the future Sometimes, you have to grab an existing problem by the scruff of its neck. It will cringe and cry. It will bring tears to your eyes. Give it a hard shake. To its demands, say "NO!" In this way, you stop focusing on the problem, and move on to the solution. You say: "YES!" You move from "NO!" to "YES!". From despair to problem-solving. From now to the future.
