Collecting rainwater is as ancient as farming itself, but rainwater harvesting is useful for modern urban households, too. All it takes is directing roof runoff through gutters and downspouts into a rain barrel or a more advanced system—one that can supply water for many, or even all, of your household needs.
The advantages are numerous, and disadvantages are few:
· Rainwater is free and suitable for landscape irrigation, power washing, filling swimming pools, ponds and fountains, flushing toilets, and more.
· With proper water filtration, rainwater can be used for any household purpose, but some areas restrict rainwater harvesting for potable uses, such as drinking and cooking.
· Rainwater harvesting helps conserve water and gives you more control over your water supply, especially in areas with water restrictions.
· Rainwater harvesting technologies are relatively inexpensive to install, from a few hundred dollars to a few thousand, but they require frequent maintenance.
· Rainwater harvesting is an excellent back-up in water emergencies, and it helps prevent stormwater drainage overflows.
