18. Ravi has planned to install Rain water harvesting in his newly constructed house. How
will it help him to conserve water?
Answers
This how Rainwater Harvesting will help him save save water:-
-Rainwater Harvesting and Utilization (is an alternative, and in many cases a better, water supply to the normal surface water based supplies from reservoirs or groundwater based supplies from wells tapped into underground aquifers.
- Rainwater harvesting helps manage stormwater run-off to prevent erosion, flooding and poor water quality in our lakes an streams.
- Rainwater can have a major impact on water supply and has been shown to be able to reduce municipal water demand enough that large new public water sourcing projects become unnecessary.
- In urban settings, up to 90% of water runs off because of sealed surfaces like roads, parking lots and roofs. In nature, up to 90% soaks into the ground. Rainwater harvesting systems counteract stormwater run off and thereby reduce flooding, erosion and ground water contamination. When combined with an infiltration system like rain gardens or an in-ground system.
- Taking water out of our lakes, reservoirs and rives effects groundwater, irrigating with rainwater helps replenish groundwater supplies.
- Infrastructure projects to increase water supply use massive amounts of energy and natural resources in addition to the obvious cost to ratepayers. Rainwater harvesting and utilization helps minimize the need for these projects.
- Municipal water treatment and pumping make up a high percentage of energy and chemicals. Rainwater systems reduce this usage.
Hope it helps!!
Answer:
Rain water harvesting system
Explanation:
it is usually present in big houses and these are one of the best sources of saving water.
When it's raining the water seeps into the pipe specially for this system and this water is usually stored in a tank or any other huge place and is used for various purposes like bathing..washing etc
