Seattle Stormwater and Drainage Code Compliance

roof gutter rainRainwater collection has become an integral part of Seattle’s construction projects, starting with design and architecture, to be in compliance with the new 2016 stormwater and drainage codes.  Collection and beneficial use can be key components toward compliance with these codes, which is especially important at the architectural design stage.

 Infiltration typically uses a detention system, which regulates and controls storm water runoff by slowing the rate of discharge to reduce impacts downstream, or a retention system, which stores stormwater runoff indefinitely, until it is lost through percolation, evaporation, or uptake by vegetation. Both are typical of rain gardens and small rain barrel systems.

Rainwater collection systems typically collect only roof runoff and conveys it to storage for future beneficial use. This can be for irrigation by combining detention and collection. Some Rainwise Program installations are combining these two in their approach toward best practices of stormwater management. Larger scale rainwater collection systems are typically comprised of corrugated steel water tanks used for irrigation, water closets, and wash down and can be included in the building’s design. 

RainBank Rainwater Systems works closely with owners, architects, engineers, and contractors in the process of design, through installation, to achieve the desired results of both efficiency and aesthetic. RainBank is a full service rainwater collection systems contracting company offering designs, permitting and construction throughout Washington State and Oregon.

How to Save Money with Seattle Area Rainfall

needle-rainWhat could you have done with last weekend’s Seattle area rainfall of around 2.5″?

If your house has 2,000 sq. ft. of roof, you could have collected about 3,000 gallons of water. That could flush toilets for a four person household for 100 days or do over 100 loads of laundry. You could supply both demands in this household for a entire year with as little as 4,000 gallons of storage with our average annual rainfall. The average demand for both of these fixtures is 48% of your household usage. That’s 48% of your water not needed to be distributed through a centralized water system. That’s 48% of you water bill, which is expected to increase consistent with demands, repairs of infrastructure, and availability. 

Rainwater collection can be part of your requirements of the new 2016 stormwater code. Our modal above mitigates over 65% of its roof runoff. With larger storage and other use, as much as 100% mitigation can be met. On site infiltration or rain gardens can also augment the drainage plan along with rainwater collection.
