Rainwater Harvesting Education, Sustainability

Sustainability Key Rainwater Harvesting Benefit

RWC Washington State

Colorado needs to look no further than Seattle and Washington State for the sustainability benefits of Rainwater harvesting.

The Colorado rainwater harvesting narrative shows that as time marches forward, some laws that were passed almost one hundred years ago should be reconsidered because they are just no longer practical. Sustainability wasn’t a factor back then, but it sure needs to be part of the equation now.

In October 2009—after years of argument—the state of Washington officially declared that people could collect and store rainwater captured from a rooftop or other “guzzler” system without a water right, as long as it is used on site and essentially isn’t hurting anybody else. San Juan County was the only one that allowed rainwater collection and potable use for single family residence as an exemption to the water rights issue before the 2009 decision.

Since then, King County recognized the benefits of rainwater collection in January 2011 for household usage, with support from State Department of Agriculture. So now, King County Department of Health not only allows, but encourages rainwater collection.

Commercial, private, and communities all are finding benefits to rainwater collection and the positive effects on the environment of the Pacific Northwest and our water supplies. The Washington State Department of Ecology continues to support rainwater collection and studies the effects of in stream flow rates (Skagit) and salmon habitat.

All Washington State counties allow for rooftop collection for non-potable use, with some allowing for potable use. Non-potable use includes irrigation, toilet facility, laundry, wash down and others that are not intended for consumption or bathing. Commercial applications are directing roof runoff to irrigation and toilet facilities, rather than having this runoff enter our bodies of water with pollutants picked up along the way. Households are not only using rainwater for non-potable use, but are having systems installed that treat and disinfect the rainwater to potable standards that are superior to city drinking water, thus conserving water by simply not allowing it to become runoff. Rural households are using rainwater collection that benefits aquifers by rainwater collection and household use, through infiltration after use. Communities are organizing communal gardening applying rainwater collection, removing the strain on small water systems, while promoting community evolvement and education.

We congratulate Colorado on its progress in exploring new (to them) sustainability methods. We welcome Colorado’s steps towards better understanding of the benefits that we in Washington State currently enjoy.

Where Will the Next Water Crisis Happen?

As investigations deepen, the Flint, Michigan water crisis has exposed “leadership failures at every level” (according to an article in the Detroit Free Press quoting U.S. House Oversight Committee Chairman Jason Chaffetz), citing “festering” long term problems and questioning the EPA’s level of attention as lead levels in Flint’s water rose to poisonous intensities.

As such, we’d like to bring you a throwback Thursday post to highlight an agency that is being proactive about ensuring that homeowners have access to and control of their water supplies.

Last year, the Skagit County Planning Department issued its first residential building permit with rainwater collection as the sole source of water. This move came in response to the in stream flow rule, which impeded Skagit Valley residential property development. Read more…

We here at RainBank believe there are good folks at governmental agencies who are being progressive about ensuring public health and safety by providing ways for residents to have access to clean, safe drinking water – a basic human right.

Skagit County’s First Residential Building Permit With RWC as Sole Source of Water

Property owners affected by the in stream flow rule in the Skagit Valley river basin now have a viable solution for residential development of their properties.

Last week, Skagit County Health Department issued a “water availability” based on rainwater collection, allowing construction of a single family residence using rainwater as the sole source of water.

The system design collects rainwater from the roof, which is pre-screened and conveyed to 10,000 gallons of storage adjacent to the house. The water is pressurized, then filtrated using sediment and carbon filters and disinfected by ultraviolet light for whole house, potable use. With an average annual rainfall of 33.2 ” and 3,500 sq. ft. of roof, 72,392 gallons are available for collection. After household use. the water is returned to the soil through the septic system and leach field just like a well system with no ill effects on the in stream flow rates.  

Simple, routine maintenance conducted by the homeowner will supply this 3 bedroom, five occupant home with a safe, reliable, clean source of potable water while benefitting “in stream flow” and salmon habitat.
