Rainwater Harvesting

Rainwater Harvesting

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit (well, shaft, or borehole), aquifer, a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens, livestock,[1] irrigation, domestic use with proper treatment, indoor heating for houses, etc. The harvested water can also be used as drinking water, longer-term storage, and for other purposes such as groundwater recharge.


Reasons For Using Rainwater Harvesting Systems

What: Rainwater harvesting will improve water supply, food production, and
            ultimately food security.
Who: Water insecure households or individuals in rural areas will benefit the
            most from rainwater harvesting systems.
How: Since rainwater harvesting leads to water supply which leads to food
            security, this will greatly contribute to income generation.

Methods of Rainwater Harvesting

In urban area rainwater flows away as surface runoff. This runoff could be caught and used for recharging aquifers by adopting appropriate methods.

It is a system of catching rainwater where it falls. In rooftop harvesting, the roof becomes the catchments, and the rainwater is collected from the roof of the house/building. It can either be stored in a tank or diverted to artificial recharge system. This method is less expensive and very effective and if implemented properly helps in augmenting the groundwater level of the area.


Dedicated to Saving LivesTypes Of Rainwater Harvesting System

The most basic form of harvesting is the humble garden water butt. Water collects in the container from drain pipes and/or natural rainfall, and is mainly used for the watering of garden plants.

This is the most common type of more professional rainwater harvesting system, particularly for domestic properties, and is generally the easiest to install.

Indirect Pumped is collected from a part of the roof which has gutters above the filter and collection tank which are in turn above all the outlets

In some situations It may be possible to have a system that functions purely through gravity, requiring no pump and therefore no energy use.
