Rainwater Harvesting

Unique Ways to Save on Your Water Bill

For ages, we've used rainwater for a variety of purposes including drinking, washing and irrigation. Although our rainwater may be too polluted to drink, it's still very suitable for other uses, like irrigation, washing and some indoor plumbing. The practice of using rainwater, called "rain water harvesting," is becoming more prevalent as water costs rise. It is not only earth-friendly, but it may also keep a little money in your pocket.


According to the U.S. Environmental Agency, an 2.5 centimetres of rain dumps 500 gallons on the roof of a typical 2,000-square-foot house. Installing a rain barrel irrigation system could save about 1,300 gallons of water during the peak summer months and that¹s more than enough runoff for basic irrigation needs.

Combine a commercially manufactured or homemade rain barrel collection system with a gravity-based drip irrigation system, and you're well on your way to saving water and maintaining healthy lawns and gardens.


The water you use to wash your clothes doesn't have to be clean enough to drink, so you could save water by connecting your washer to a rainwater collection tank. You'll need to install an inexpensive shower power booster pump so that the water pressure will remain at the proper level for the washing machine.

Additionally, if you use biodegradable soap, you could use the same water that you laundered your clothes in to water your yard. Talk about double the water savings!

Indoor Plumbing

Did you know that older toilets can use up to seven gallons of water with every flush? New standards specify that toilets can only use up to 1.6 gallons per flush (GPF), but even with this lowered amount of water needed to flush toilets, using rainwater for this task seems like a no brainer.

Rainwater is a valuable natural resource that has been collected by households for ages. With rising costs of treated water provided to the community, using this free natural resource is a good way to decrease your dependence on supplied water. Opportunities and legislation for rainwater collection and use vary by location, so first check with your local governmental entity before installing a rainwater harvesting system.
