Take a bow to whoever originally thought up rain water harvesting.
What a simple idea that can make such a big difference!
Why let off water that can be used when you need it?
Rainwater harvesting systems are simple to implement, robust, and can help your house be water secure even during water crisis elsewhere.
This one time expense and effort can save tons and tons of water, and more important, give you water security if your household depends on groundwater at your location!
Sure, it might not just be you alone who benefits from rainwater harvesting your proximate local community could, but you can be a bit generous, can’t you!
