RAINWATER HARVESTING:
Rain water harvesting is the collection of rainwater into the man made resources or any natural resource like pond, lake, etc at the same place where it falls from rooftops or ground. Two main techniques of rainwater harvesting are storage for future use and recharge into the ground. It can be used for crop harvesting, gardening, toilets, etc. Following are the benefits of rainwater harvesting at individual or city-wide level:

- It helps in reducing the water supply bills especially to the institutions.
Rainwater recharged to the ground positively affects groundwater quality by diluting fluorides, nitrates and its salinity.
It contains almost neutral pH and zero hardness which makes it more able to be used in homes, industries, institutions and other commercial establishments.
It may reduce the stress of public water supply sources.
Recharge of rainwater to the ground prevents sea-water immersion into the fresh water bodies in the coastal areas.
It helps in controlling urban flooding if people do rainwater harvesting from rooftops.
It reduces water demands of people from the municipality thus lessens energy consumption too in distributing water all through the city.

Introduction to Rainwater Harvesting
Rainwater harvesting (RWH) is a sustainable practice that collects and stores rainwater for various uses. It's an effective method to conserve water, especially in areas facing water scarcity.
Methods of Rainwater Harvesting
There are several methods of rainwater harvesting, each suitable for different environments and needs:
  • Rooftop Rainwater Harvesting:
    This method involves collecting rainwater from rooftops and directing it into storage tanks. It is one of the most common and efficient methods.
  • Surface Runoff Harvesting:
    This technique captures rainwater that runs off surfaces like roads or pavements. It can be collected in trenches or ponds for later use.
  • Subsurface Catchment:
    This involves creating underground reservoirs that capture rainwater. It reduces evaporation losses and helps recharge groundwater.
  • Check Dams:
    Small barriers are constructed across streams to slow down water flow, allowing it to infiltrate into the ground. This method is effective in rural areas.
  • Recharge Pits:
    These are excavated pits filled with stones or gravel to facilitate water infiltration. They help to recharge groundwater levels significantly.

Benefits of Rainwater Harvesting
  • Reduces dependence on municipal water supply.
  • Minimizes soil erosion and flooding.
  • Improves groundwater recharge.
  • Provides a sustainable water source for irrigation and domestic needs.

Conclusion
Implementing rainwater harvesting methods can significantly contribute to water conservation efforts, ensuring a sustainable future.

Methods of Rainwater Harvesting : 

Catchment : 
Any surface or the paved areas can be treated as catchment. Even the footpaths and roads can act as the catchment, as these areas too receive the direct rainfall. Rooftops are the best among them because of the large coefficient of run off generated from them and there are less chances of contamination of water.

Conveyance : 
Conveyance system basically includes rain gutters and down pipes which collects the rain water from catchment to the storage tank. These rain gutters are usually built during the time of construction. They need to be designed appropriately as to avoid the loss of water during the conveyance process. 

Storage : 
The most important part of the rain water harvesting is the storage system. The storage system is designed according to the amount of water that is to be stored. The design and site (location) of the storage or the recharge system should be properly chosen. The areas which receives the rainfall frequently, there a simple storage system could be constructed, to meet the daily water requirements. Otherwise the areas which receive the lesser rainfall, there the storage systems are quite essential. Rain barrels, underground or open slumps are mostly used to collect rain water. Make sure that the storage system is properly sealed and does nor leak. Use Chlorine from time to time to keep the water clean. 

Benefits of Rainwater Harvesting : Rainwater harvesting first of all increases water security. It is the perfect solution to meet water requirements especially in the areas which do not have sufficient water resources. It helps in improving the quality of the ground water and increasing the level of the ground level. It also helps in improving the overall floral system. It reduces the loss of top layer of the soil. If we capture the water directly we need not to depend much on the water storage dams. It is the good solution to the increasing water crises. Rain water harvesting reduces the flooding on roads and further prevents it from contamination. And in the last it decreases the menace of floods on regional scale.
