Rain Barrels - Harvesting Rainwater with a Rain Barrel

By , About.com Guide

What is a Rain Barrel:
A rain barrel is a container -- usually constructed of plastic or wood -- that is used to collect and hold rainwater for later use. In most instances, the barrel connects to the end of a gutter downspout to collect rooftop runoff.
How Much Do Rain Barrels Cost:
Ready-made rain barrels sell for anywhere between $50-$200, depending on features; but you can make your own rain barrel for as little as $20-$30.
How to Choose the Right Rain Barrel for Your Application:

When choosing a rain barrel, you first need to determine how much water you hope or expect to capture. Most rain barrels have a 60 gallon capacity, but you can also find larger barrels on the market.

Regardless of the size that you choose, try to to seek out a model with a mesh screen at the top of the barrel. This will help to filter out debris and prevent mosquitoes from breeding in the water – a worthwhile feature indeed.

Also, worth seeking out: a barrel with a built in spigot on the side, so that you can attach a hose or fill up things like watering cans and wash buckets.

Rainwater Can be Used for:
Captured rainwater can be used to water your yard, indoor and outdoor plants and to wash your car. With some modifications to your plumbing, it can also be used to flush toilets and wash laundry.
Why Bother with a Rain Barrel:
To understand why you should bother with a rain barrel, consider these two statistics:
  • One-inch of rainfall on a 1,000 square-foot roof generates 623 gallons of runoff
  • In the summer, 40% of a typical household's water use goes to watering gardens and lawns
Tips and Warnings:

1. To prevent injury to children and pets, ensure that the tops of your rain barrels are kept securly in place, and that the barrels can not be overturned easily.
2. Indoor rainwater use is not permitted in all areas. Check with your local goverment before making any alterations to your indoor plumbing.
