Water is a precious, essential and an abiotic component of the ecosystem. We all use water for different kinds of day-to-day activities, such as cleaning, washing, bathing, cooking, drinking and other domestic and industrial uses. We all use water for different kinds of day-to-day activities, such as cleaning, washing, bathing, cooking, drinking and other domestic and industrial uses. Today we all are heading toward the scarcity of water, and this is mainly because of the lack of water conservation and pollution of water bodies. So, let us not waste a drop of water and start conserving water for further use. There are different methods used for conserving water. Rainwater harvesting is the simple process or technology used to conserve rainwater by collecting, storing, conveying and purifying of rainwater that runs off from rooftops, parks, roads, open grounds, etc. for later use.
The process of rainwater harvesting involves the collection and the storage of rainwater with the help of artificially designed systems that run off naturally or man-made catchment areas like- the rooftop, compounds, rock surface, hill slopes, artificially repaired impervious or semi-pervious land surface.
Several factors play a vital role in the amount of water harvested. Some of these factors are:
- The quantum of runoff
- Features of the catchments
- Impact on the environment
- Availability of the technology
- The capacity of the storage tanks
- Types of the roof, its slope and its materials
- The frequency, quantity and the quality of the rainfall
- The speed and ease with which the rainwater penetrates through the subsoil to recharge the groundwater.
Types of RainWater Harvesting
The pump is located within the underground tank and harvested water is simply pumped directly to the WCs or other appliances.
An indirect connection is a connection to a private drain that then goes into a public sewer.
The harvested water is first pumped to a high-level tank (header tank), then allowed to supply the outlets by gravity alone.
The gathered rainwater can be used for agricultural purposes.
The requirement of water for feeding the livestock can be met.
Waterlogging on roads can be saved from being inundated.
The quantity of water can be raised, and soil erosion can be checked.
Wastage of water flowing through drain, gutter or any water course of ant type may be stopped.
The ever increasing demand for water can be satisfied.
A building’s terrace or rooftop may serve as such a catchment.
The pipes are yet another crucial element of the rainwater collection system.
The initial accumulation of rainwater is flushed out.

The collected water is kept in the storage container.
