Rainwater harvesting is a method of collecting and storing rainwater for future use such as irrigation, bathing, and cleaning. It is an important practice because surface water sources are inadequate to meet demand, forcing reliance on groundwater. However, rapid urbanization has decreased the ability of rainwater to replenish groundwater levels. The advantages of rainwater harvesting include low maintenance and reduced water bills since collected rainwater can be used for non-drinking purposes. The main disadvantage is that rainfall amounts are unpredictable and limited rainfall areas may not be suitable for full dependence on rainwater alone.

2. What is it?
 Rainwater Harvesting
is a cheap method of
storing and
harvesting water for
future use.
 We can use that water
for irrigation,
bathing, washing
cars, cleaning
clothes.

3. Why is it important?
 Rain water harvesting is
essential because : Surface water is inadequate
to meet our demand and
we have to depend on
ground water.
 Due to rapid urbanization,
infiltration of rain water
into the sub-soil has
decreased drastically and
recharging of ground water
has diminished.

4. Advantages of Rainwater Harvesting
 Advantages of Rainwater
Harvesting
 1. Easy to
Maintain: Utilizing the
rainwater harvesting
system provides certain
advantages to the
community.
 2. Reducing Water Bills:
Water collected in the
rainwater harvesting
system can be put to use
for several non-drinking
functions as well.

5. Disadvantages of Rainwater harvesting
 Disadvantages of
Rainwater Harvesting
 Unpredictable
Rainfall: Rainfall is hard to
predict and sometimes little
or no rainfall can limit the
supply of rainwater. It is not
advisable to depend on
rainwater alone for all your
water needs in areas where
there is limited rainfall.
Rainwater harvesting is
suitable in those areas that
receive plenty of rainfall.
