As we’ve written many times over the years, you can create your own water supply, not just for drinking, but also for laundry, toilet and irrigation in a commercial and residential environment, depending on where your home or business is located.
Here’s an article we shared in June 2014, about how rainwater collection is a reliable water supply alternative to city or well water.
“Below are some notable findings on rainwater collection compiled by ARCSA from the 2013 Report Card on America’s Infrastructure from the American Society of Civil Engineers, the U.S. Chamber of Commerce and the National Association of Water Companies:” read more
Do you know that by installing a rainwater collection system for toilet flushing and laundry facility, Seattle homeowners can save big bucks on their water and sewer bill? Considering the expected price increases over the next 5 – 10 years on these utilities, a return on investment is a reasonable expectation.
A study by the American Water Works Association to determine end use of water in 100 single family homes was conducted back in 1999. Even though the study is dated, it is a good indicator of average single family usage with regard to rainwater collection.
The study found that 27.7 % total household use of water is used in toilet flushing and 20.9% total household water use is by laundry facility. These uses can be improved by low usage fixtures such as dual flush toilets and front load washers, however, they do indicate an average of 48.6 % water consumption by these two fixtures.
New home construction in the Seattle area is required to mitigate roof runoff on impervious surfaces on site. Costs of infiltration can be expensive. A well-designed and installed rainwater catchment system uses this runoff water for domestic use rather than infiltration. By redirecting the costs of infiltration design and construction and considering the savings on water and sewer bills, the average Seattle home owner can see a significant cost savings as well as a return on investment.
With all of the news about aging water systems, poisoned and tainted public water, conservation and sustainability, isn’t it time to design and build your rainwater collection system?

According to a press release issued by Drexel’s College of Engineering, “research by a team of Drexel University environmental engineers indicates that it rains enough in Philadelphia, New York, Seattle and Chicago that if homeowners had a way to collect and store the rain falling on their roofs, they could flush their toilets often without having to use a drop of municipal water.”
Franco Montalto, P.E., PhD, an associate professor in Drexel’s College of Engineering, and director of its Sustainable Water Resource Engineering Lab states, “Philadelphia and Seattle are the two cities where percent water savings would be greatest if residential neighborhoods were all equipped with rainwater harvesting systems.”
RainBank Rainwater Systems has been designing and constructing systems throughout the Pacific Northwest for more than 15 years. Many of our Seattle customers have included rainwater collection as part of new residential construction and retrofitted existing homes. Toilet flushing, laundry facility, and irrigation can all be supplied with non potable rainwater. Whole house usage or potable water can be achieved with proper filtration and disinfection as well.
You don’t need a lot of storage to save money. RainBank Rainwater Systems has designed and installed 3,000 gallon systems that supply an average 2,000 sq. ft. home with 60% of its household use, simply because of the amount of fall and winter rainfall.
