U.S. Water Supply Challenges

This year marks ARCSA‘s 20th anniversary, and its annual conference will put the focus on Rainwater Harvesting: Solutions to U.S. Water Supply Challenges.

The annual rainwater collection conference, to be held in Phoenix, AZ this November, will offer presentations from educators, industry professionals, and keynote speakers, with topics including legislative action, codes and standards, guidelines, along with panel discussions, and workshops centered around rainwater collection.

Ken Blair, RainBank LLCRainBank’s president Ken Blair was tapped to present a session on Urban Rainwater Collection and its effects on stormwater runoff mitigation.

Additionally, Ken will participate in an advanced continuing education course to attain the designation of Inspection Specialist (IS), augmenting his already achieved, Accredited Professional (AP) qualification and lifetime member status.

Adding the IS accreditation to its list of qualifications solidly identifies RainBank as the leader in rainwater catchment systems design and installation for commercial and residential customers, especially for Seattle area customers and classifies RainBank as the most qualified, up to date, professional Rainwater Collection company in the industry.

Swimming Pool Repurposed for Underground Rainwater Collection

underground tanks former swimming pool7,200 gallons of collected rainwater for household usage has no visual impact for this newly constructed Bellevue home. The homeowner wanted to have a rainwater catchment system to provide water for the toilet and laundry facility, but he did not want large, above ground water tanks interfering with the landscaping of his backyard.

Residential Underground Rainwater Collection Tank-AfterThe solution: excavating the old cement swimming pool and placing four 1800 gallon poly water tanks in its place, creating an underground rainwater collection system.  All the tanks are connected with a manifold for equalization and supply a pressure tank and filtration in the mechanical room for usage. Solenoid valves provide automatic switching from rainwater to city water if the tanks should run low, but will switch back to rainwater when the tanks receive more water from the roof.

Gutter screens were installed, along with a vortex filter, which will eliminate debris from entering the storage tanks. In the mechanical room, a sediment filter will remove fine sediment, followed by a carbon filter to eliminate color and odor.

With auto switching, the homeowner will never know the difference (other than his reduced water bill) and he finds the underground rainwater collection system aesthetically appealing.

What Weather Pattern Will Seattle See This Winter?

ocean-surfWhat type of weather pattern can we expect in the Seattle area this winter?

According to the latest NOAA forecast, “For more than a year now we have been experiencing a ‘La Nada’ weather pattern, with ‘El Niño’ to develop toward the end of the year.” Warming of the equatorial Pacific Ocean will trend toward a warm and dry fall and winter across the Pacific Northwest while sending the jet stream farther to the South bringing California much needed wetter weather. This means less snow pack and less lowland rain for the Seattle area.

However the NOAA stats suggest we are not in the El Niño pattern yet, with .46″ of rainfall this last Saturday and a weekly total of 2.18″ this past week. A monthly total so far of 2.90″ is less than the average monthly total for October of 3.24″.

A 2,000 sq ft home in Seattle could have collected 3,613.4 gallons of water from that 2.90″. With an average rainfall of 36″ that same home could collect almost 45,000 gallons. With approximately 12,000 gallons of storage, that home would have a budget of 3,750 gallon average monthly use and enough water stored to supply their summer demand.

Seattle is one of the best suited areas for rainwater catchment regardless of climatic weather patterns we face.
