The Department of Ecology, DOE, released a statement on Oct. 9 to clarify the existing policy regarding collection of rainwater via catchment systems and guzzlers.

DOE determined the existing law does not to require a permit for the on-site storage and use of rooftop or guzzler collected rainwater.

A guzzler is a device used to catch and store rainwater to provide drinking water for wildlife, livestock, or birds.

Michael Durland of PurRain in Deer Harbor has been working with rainwater catchment systems since 1979. PurRain has installed catchments throughout the San Juan islands and other locations worldwide.

Durland says the DOE clarification probably won’t make much difference in the process of installing supplemental catchment systems in San Juan County.

“San Juan County has been very liberal on this for several years,” Durland said.

Kat Fennell of PurRain says there is no single way to install a supplemental catchment system.

“Each system is site specific based on the needs of the family and the lay of the land,” Fennell said.

Most people adding a catchment system use it to irrigate a garden.

Environmental Health manager Mark Tompkins explains there is nothing required from the county for catchment that requires no additional plumbing. For new construction and existing homes being retrofitted or remodeled, there is a water availability process including an application, certificate, and guidelines.

“I think people here have found it very beneficial in some situations,” Tompkins said.
