Essay on Rainwater Harvesting: To beat water scarcity and sustain lives across continents, rainwater harvesting is a practice followed by nations worldwide. It is one of the most innovative solutions to save water. It helps to balance water cycle, avoid rainwater flooding in low lying regions, and better utilise rainwater for purposes like gardening, washing and cleaning purposes. Government policies have made it compulsory to implement rainwater harvesting at residential and commercial buildings.

Rainwater Harvesting is a form of harvest in which rainfall is gathered and deposited for potential use instead of being allowed from getting washed out. Rainwater can be collected from rivers or dome to a bottomless pit (well, pipe, or borer), aquifer, percolated pond or collected from dew or fog with filets or other devices. The uses include greenhouse water, cattle irrigation, household use, indoor heating for houses, etc. The extracted water can also be used as drinking water, for long-term storage and other uses, including irrigation of groundwater.
India has received significant water supplies from nature. We have seasonal rivers like the Ganga, Brahmaputra, Yamuna, Beas and others with their affluent and distributors, in the north and eastern India. In central and peninsular India, we have spring and rain-fed rivers like the Godavari, Krishna, Narmada, Tapti and Kaveri. Notwithstanding these immense available water supplies, we face a countrywide water crisis. The growing population, growing industrialization and developing agriculture have raised the need for water over the years.
Rainwater Harvesting in India
In India, it is more than 4000 years since the rainwater was harvested. It is a simple method to capture and store rainwater. Since ancient times, rainwater irrigation systems have been used as a source of potable water, irrigated water as well as agricultural water. The systems are simple to create from cheap, locally-produced materials and have proven popular in most areas. The most significant benefit of rainwater is that water quality is usually good, and no preparation before consuming is needed.
There are several methods to harness rainwater, ranging from relatively necessary to highly complex industrial systems. Usually, on the roof or the ground, rainwater is collected. The rate at which rainwater can be obtained from any system depends entirely on the strength of the precipitation and the area and general performance of the systems in operation.
Methods of Rainwater Harvesting
Some of the most common ways to harness and treat urban rainwater are:
- Surface Runoff Harvesting: The most effective approach in urban areas is Surface Runoff harvesting. Soil water sources are redirected here and deposited on the soil or underground to be used for future uses in specially built reservoirs. This ensures the constant water supply for general domestic applications as well as clean, drinking water.
- Rooftop Rainwater Harvesting: Rooftop rainwater harvesting is the most common alternative for urban harvesting. The system is accessible in a single home setting, hospitals, colleges and other academic buildings with more roof space. The rooftop rainwater storage idea is fundamental and easy to do. A container has to be installed or put under the surface of the roof, which collects and converts the rainwater from timber, bamboo or PVC pipes. While this is the basic principle, it is much more complex to harness industry-grade rooftop rainwater in large complexes.
- Recharge Pits: The creation of refill pits to carry rainwater is also a growing rainwater harvesting method. Recharge boxes can be of any size and shape, depending on the strength of plumage in a given area. These recharge pits must be filled with gross sand, boulders and gravel which act as natural filters that protect the soil and the soil is usually carried by the first rainwater flood.
