More Residential Potable Use Permitted in Washington State

Rainwater Collection for residential potable use is increasingly being accepted by Washington State counties.

potable water use

What started in San Juan county years ago with a county exemption of the 1,800’s water rights laws, rainwater collection for residential potable use is gaining momentum up and down the I-5 corridor. Whatcom, Skagit, Snohomish, and King counties all have adopted residential potable rainwater collection systems as an alternative water source for residential building permits. Each county has its own policies & procedures and guidelines for designs and installation available to the public.

The national organizations, American Rainwater Catchment Systems Association (ARCSA) , American Society of Plumbing Engineers,  (ASPE) , and the American National Standards Institute (ANSI) developed the standard ARCSA/ASPE/ANSI 63 as a guideline for professionals and local governments in implementing rainwater collection and was updated in 2020. As more counties are expressing interest in rainwater collection as a viable source for domestic potable use, RainBank Rainwater Systems continues to provide updated information for these organizations to formulate decisions, and help guide them in their policies and procedures with regard to implementing rainwater collection.

With 20 years of experience, RainBank Rainwater Systems has been serving all Washington State counties with quality engineered systems and professional installations, using only the best components.

After all, it is your water supply and we take it seriously.

Potable Residential Rainwater Use is On the Rise

Popotable residential rainwater collectiontable residential use of collected rainwater is on the rise since the statewide water rights laws were challenged in 2006 by the Washington Department of Ecology, allowing the entire state of Washington to collect and use rainwater for non-potable (non-drinking) use. San Juan County had been awarded an exemption to the 1800’s water rights laws and was already issuing  residential building permits with rainwater collection as the only source of water. RainBank’s president, Ken Blair, was personally awarded a building permit in 2002 for his “water availability” being the only source of water for his household. It was not the first, but was certainly at the forefront of rainwater collection’s progression and, throughout the years, RainBank, has continued with that effort.

For close to 20 years, RainBank has shared its deep rainwater collection knowledge, working with many counties as they move toward increased adoption of potable residential rainwater collection systems for single family residences, and remains committed to providing quality engineered designs, professionally installed.
