Rain is a type of precipitation, a product of the condensation of atmospheric water vapor that is deposited on the Earth’s surface. It forms when separate drops of water fall to the Earth from clouds.
Rainwater is water before it hits the ground. When it hits the ground it becomes stormwater.
Rainwater it is not greywater. Greywater comes from bathroom sinks, showers and laundry.
Rainwater is much better then potable water for irrigation, because of the lack of chlorine and other chemicals used in potable water treatment. Plants thrive under irrigation with stored rainwater and may grow 20%-30% more using rainwater for irrigation.
When properly collected rainwater is valued for its purity and softness. It has a nearly neutral pH, and is free from disinfection by-products, salts, minerals, and other natural and man-made contaminants.
Rainwater harvesting is the accumulation and storing, of rainwater for a later use.
Once collected it can be used for a variety of uses. Irrigation, toilets, laundry, cleaning, fountains, commercial applications and even drinking.
Rainwater Harvesting is a more environmentally correct solution to free water then a well. Well water can also contain minerals that may have to be treated before use. Wells draw down the water table which can lower rivers and lakes, as well as run dry. Ground water can be from decades to hundreds of years old. How long will it take to replenish that water.
Why should you collect rain water?
Drought is one of the most important reasons to collect rainwater. There might be months or years that very little of the water collected is used, however there will be years where every single drop is used.
The good news is Georgia has an abundant amount of precipitation and with a large roof area tanks can fill quickly.
Collecting rainwater on site reduces the demand for municipal water which saves infrastructure and energy costs for supplier.
Rainwater helps reduce the stormwater issue in urban areas by storing rain during the storm and using it at a later time to recharge the ground water.
