What is the Most Common Use of Collected Rainwater?

Do you know that the most common use of collected rainwater is not for drinking? Here’s a prior post, which helps answer this question – and explains why non-potable use of rainwater is so popular – and sustainable.

The most common use of rainwater collection is for non-potable use. Irrigation, water features, wash down, toilet, and laundry are all non-potable uses that can have a positive effect on water conservation. A properly designed and installed rainwater collection system will provide enough water to support these desired uses with less impact on our water supply.

Rainwater is essentially free of pollution, so it can be stored without much more than screening. Storage can be underground, above ground, metal, plastic, or fiberglass. If irrigation is the desired use, keep in mind that approximately .623 gallons per sq ft of planting, per week is required for the healthy growth of plants, therefore storage volumes can be a concern in design due to space and costs. Conveyance can be gravity if there is enough head. Head is .4 lbs per foot of elevation. A pressure pump might be necessary to achieve the desired pressure needed. Sediment filtration for a simple irrigation system should be all that is needed to ensure emitters and soaker hoses perform as expected.

Water features such as fountains can recirculate the water being used, so very little storage would be required. Sediment and carbon filtration would be needed to keep pumps and nozzles working properly. A carbon filter would be helpful to keep odor to a minimum.

Wash down facilities can use rainwater collection and save money on their water bills by using rainwater collection as the rinse water. With enough storage, a large fleet can be washed with recycled wash water and rinsed with collected rainwater. Again, sediment and carbon filtration would be the only filtration needed. Wash down of equipment, whether construction or farming, can benefit from rainwater collection.

Toilet and laundry facilities for residential and commercial applications are becoming more popular with new construction. Rather than infiltration, which is mandated, why not use that water. Simple pumping and filtration of stored water is all the treatment needed. A return on investment can be achieved within a few years.

There are a wide range of uses for rainwater collection. With a little bit of imagination, you might come up with a use for rainwater collection that could save you money.

So, the next time you think collecting rainwater for drinking purposes is most common, think again – there are many more uses that are beneficial and sustainable.

Rainwater for Vehicle Washdown

A five-year old rainwater harvesting system built for the city of Guelph, Ontario, Canada  received an award for saving enough drinking water to fill four Olympic-sized swimming pools – by using captured rain for vehicle washdown.

The Water’s Next national awards program honors the achievements and ideas of individuals and companies that successfully work to change water in Canada.

Award categories include:

Business Leader: Person in the private sector that has demonstrated significant leadership and innovation in the water sector.

Academic Leader: Person in the academic sector that has demonstrated significant leadership, innovation, and scientific excellence in the water sector.

Non-Government Leader: Person in the non-government sector that has demonstrated significant leadership, innovation, and influence in the water sector.

Government (includes municipalities, agencies, watershed authorities, and First Nations government) Person in the public sector that has demonstrated significant leadership, innovation, and influence in the public sector, towards the benefit of Canada’s water resources.

Young Professionals: Individual under the age of 30 working in the water sector who has demonstrated exemplary leadership, innovation, and growth potential.

An additional benefit of using rainwater to clean city buses is that the captured rainwater is softer than groundwater, therefore, less cleaning products are needed, which saves money for the city.

“We rely on a groundwater supply in Guelph, and we need to be smart about how we use water—at home, at work and at our City facilities,” said Emily Stahl, manager of technical services for the City’s Water Services department. “It makes sense to match the water supply provided with the use, and naturally soft rainwater is better for washing buses, and cars at home too.”
