write a short note on rainwater harvesting

Here's the answer:
》Rainwater Harvesting:
It means to make the optimum use of rain when it occurs. Under this concept, rainwater is collected and stored in man-made underground or surface tanks and thus its loss through surface run-off, seepage and evaporation is prevented. It is then used during drier months, generally from March to May end, when there is scarcity of water. Such prevention of loss of rainwater by run-off also recharges the groundwater.

Hope this helps!
1.Use native plants in your landscape. They look great, and don't need much water or fertilizer. Also choose grass varieties for your lawn that are adapted for your region's climate, reducing the need for extensive watering or chemical applications.
2.Use fewer chemicals around your home and yard, and make sure to dispose of them properly - don't dump them on the ground!
3.Properly dispose of potentially toxic substances like unused chemicals, pharmaceuticals, paint, motor oil, and other substances. Many communities hold household hazardous waste collections or sites - contact your local health department to find one near you.
4.Shut off the water when you brush your teeth or shaving, and don't let it run while waiting for it to get cold. Keep a pitcher of cold water in the fridge instead.
5.Check all the faucets, fixtures, toilets, and taps in your home for leaks and fix them right away, or install water conserving models.
6.Limit yourself to just a five minute shower, and challenge your family members to do the same! Also, make sure to only run full loads in the dish and clothes washer.
7.Water the lawn and plants during the coolest parts of the day and only when they truly need it. Make sure you, your family, and your neighbors obey any watering restrictions during dry periods.
8.Reduce the amount of "stuff" you use and reuse what you can. Recycle paper, plastic, cardboard, glass, aluminum and other materials.
9.Use all natural/nontoxic household cleaners whenever possible. Materials such as lemon juice, baking soda, and vinegar make great cleaning products, are inexpensive, and environmentally-friendly.
