Environment, Rainwater Catchment

Welcome to Washington’s Rainy Season

Seattle Downtown After RainOctober 1 is the official start of the rainy season in Washington State and even though annual rainfall met expectations, another dry, warm winter is predicted for the region. This means that the snowpack – the summer rain bank (see what I did there?) will be missing in action for another year.

According to the Department of Ecology’s drought page, “despite recent rains and some boost for stream flows, extreme drought still covers two-thirds of Washington state.”

Now would be a good time to come up with a personal drought contingency plan, since Mother Nature isn’t going to provide relief any time soon. Washington state’s drought plan, released in 1992, refers to fish and timber harvesting, but makes no mention of rain harvesting.

When planning a rainwater collection system, you must account for the amount and intensity of the average rainfall in your area. That information is usually available at the county level, but can also be captured via National Oceanographic and Atmospheric, Administration (NOAA) and the National Climatic Data Center.

For a small system, you can head to your local hardware store, purchase a rain barrel, hook it up and, at the very least, can collect water for your garden.

For a whole house, or commercial system, work with a pro that knows how to design and install the most thoughtful system, which is customized to your specific needs. Ask questions; provide information about your roof size and materials, family size, whether you want to capture water for drinking, irrigation or laundry, etc.

When you work with an accredited professional rainwater harvesting installer and designer, the outcome will be a system to meet your water needs for years to come – and it will add value to your home or business.

Water Conservation & Rainwater Collection Lag In Conservation Efforts

reservoir-69214_640Green building, low carbon emissions and solar power have all gotten a lot of press in the past couple of decades. What seems to be lagging behind is water conservation and rainwater collection. All are important for sustainability, but without water, it won’t matter. WE are naturally dependent on water; we cannot live without clean drinking water.

Tap water is relatively cheap – pennies on the dollar. WE pay very little for it due to bulk purchasing from manufacturing and agriculture. We have clean, safe drinking water piped to our homes and all we need to do is turn on the tap without giving it much thought at all.

What goes on behind the scenes is not a concern to most. Chlorine to disinfect along with fluoride for the health of our children’s teeth is all done by our water suppliers. All we have to do is pay our bill every month.

That is changing however; our infrastructure is beginning to show signs of aging. Boil your water alerts are becoming more commonplace. Pollutants are affecting our municipal water supplies more often.

Shortages due to drought conditions have affected many of our western states – the most newsworthy being California, where Folsom Lake,Northern California reservoir has mysteriously run dry, leaving thousands of fish dead.   (Is anyone minding the store in California?)  Washington State is also experiencing the worst drought ever recorded.

Small efforts are being made to get the word out by water suppliers. Voluntary water reduction has achieved a small percentage of actual impact since the drought is continuing into fall so far. Low snow pack is expected again this winter in the Cascades, both north and south. Efforts by water suppliers will be focused on education about conservation, but old habits are hard to break when water is so cheap. Homeowners and businesses can expect increases in prices, but that will have little effect on conservation. Breakdowns in infrastructure, accidental releases, and more contamination will become more common in the very near future.

Private rainwater collection will have the most positive effect on water shortages in the near future. A simple system to irrigate landscaping will save hundreds of millions of gallons of municipal water next summer. Toilet, laundry facilities, and wash down using rainwater collection might make the difference in municipal supply shortfalls. A potable whole house system provides a legal, viable source that puts the owner as being his own purveyor of his or her water source. Rainwater is a clean, reliable water source than can be collected during those rainy periods and stored for dry months.

Progressive thinking on all sustainability efforts is good for the health of our planet, but water conservation and rainwater collection will be the most important.

Water Supply Predictions from Seattle Public Utilities

1 Comment

Seattle Downtown After RainThe water supply prediction scenarios from Seattle Public Utilities are in – and the outlook isn’t good for Seattle and Washingtonians.

According to an article on Grist.org titled, This Drought is so Bad That Even Seattle is Running Out of Water, “Almost all the future scenarios modeled by SPU showed big drops in what’s known in water-utility lingo as “firm yield”: the amount of water that can be reliably delivered. Even assuming a drastic cutback in the amount of greenhouse gasses being emitted today, Seattle is looking at reduced firm yield of an average of about 30 percent through 2050, according to three of these future climate simulations. …”

One option for increasing water supply includes drawing water from Lake Youngs, but that might pull mud into the water supply, requiring expensive water treatment. Water from Puget Sound is an option but that would involve costly desalination.

So, what’s one of the country’s the fastest-growing cities to do? Although Seattleites have been proactive about conserving water usage over the last 50 years with efforts like low-flow toilets, there’s only so much cutting back you can do when supply is tight.

An article on InvestigateWest titled, Climate Change is Darkening Seattle’s Water Forecast, shares that water supply predictions are dire, even though models may be incomplete and involve guesswork and assumptions based on “what-if” scenarios.

“Quietly unveiled to regional water managers over the summer, the admittedly incomplete — and yet extremely sobering — calculations show the amount of water Seattleites can count on could be reduced by as much as half over the next 35 years and nearly three-quarters by the end of the century.”

The article goes on to share: “The climate models are not perfect,” acknowledges SPU climate researcher Paul Fleming. But these simulations are clearly showing that “climate change will increase the magnitude and the likelihood of those events occurring,” Fleming said.”

Seattle, it’s time to go beyond conservation efforts like taking shorter showers and running your dishwasher less often. Do you know that with rainwater collection, you can have your own supply of water for washing laundry and flushing toilets? In some areas, you can even collect your own drinking water.
