Project Abstract
Water scarcity is serious problem throughout the
world for both urban and rural community.
Rainwater harvesting is defined as process of
collecting rainwater into storage tanks either
underground or on rooftops and use the water for
household purposes.
This process will reduce soil erosion and also will
reach the demand for water in the world.
Introduction
What is Rain Water Harvesting?
Rainwater harvesting (RWH) is the collection and storage of
rainwater, instead allowing it to run; Rainwater is collected from a
roof-like surface and transmitted to a tank, cistern, deep pit (well,
shaft, or borehole), aquifer, or a reservoir with purification so that
it seeps down and restores the groundwater.
Rainwater harvesting is one of the simplest and oldest methods
of self supply of water for households, and residential and
household-scale projects, usually financed by the user. However,
larger systems for schools, hospitals, and other facilities can run
up costs only able to be financed by owners, organizations, and
governmental units.
Literature survey
Karnataka State Council for Science and Technology (KSCST) is actively
participating in the socially relevant, environment friendly water
conservation measures and has been providing cost effective solutions
since its inception. Rainwater Harvesting (RWH) Cell at KSCST is established
to study the needs of the people and provide sustainable and simple
solutions through innovation and implementation pertinent to Rainwater
Harvesting and Ground water recharge
Tamil Nadu is one of the most urbanised states with 48.45 per cent of its
population residing in urban areas. Tamil Nadu gets precipitation from the
north-east in addition to the south-west monsoons. Variation in the
monsoon has a severe effect on economic life and also the livelihood of its
people specifically residing in the rural areas.
Objectives
Reducing loss of water by its running off.
Avoiding flooding of roads.
Meeting the demands of increasing water.
Reducing groundwater contamination.
Increase available water during dry season.
Rainwater harvesting is a way of capturing and storing water
during rainy periods for use in times when there is little to no
rain available.
Reduce flooding and erosion.
Methodology
To design a rainwater harvesting system we should collecting the rainwater
and subsurface water in a hygienic way.
The different methods of rainwater harvesting are:-
1. Surface runoff harvesting-
In urban areas, rainwater flows away as surface runoff. This runoff can be
caught and used for recharging aquifers by adopting appropriate methods.
2. Rooftop rainwater harvesting-
It is a system of catching rainwater where it falls. In rooftop harvesting, the
roof becomes the catchment, and the rainwater is collected from the roof
of the house/building.
Project outcomes
It reduces soil erosion and flood hazards by
collecting rainwater and reducing the flow of
stormwater to prevent urban flooding. Most
buildings that utilize rainwater harvesting systems
have a built-in catchment area on top of the roof,
which has a capacity of collecting large volumes
of water in case of rainstorms
