Can You Collect Rainwater in Seattle’s Tight Living Space?

Space_Needle_Mount_Ranier_Seattle_Washington_USAYou live in Seattle, where space is at a premium. You may not have a large lawn for tank placement, but you still want to live sustainably. You’ve already reduced your household and business energy usage and you recycle and reuse products to extend their life. So, how can you capture a vital resource by collecting rainwater in Seattle’s tight living space?

  • Just like rural homeowners, urban households can benefit from rainwater collection. Unlike rural homes, most city homes have less space available for storage. Slim line water tanks and underground storage options allow those who live in an urban environment to collect, store, and use rainwater for a number of purposes.

A 2,000 square foot roof in Seattle will yield over 44,000 gallons of water annually. Even with only 3,000 gallons of storage, winter use can be as much as 100% or can be stored for summer irrigation demands. See chart below  – an average 2,000 square foot roof yields over 44, 000 gallons with only 3,000 gallons of storage capacity based on 120 gallons of daily demand.  (click the image for larger view)
  • Rainwater is a clean source of water that needs very little treatment for irrigation, toilet flushing, or laundry facilities. Further treatment with UV disinfection allows for whole house demands including drinking water. With more demands on our water districts due to drought conditions, every drop helps. Why not benefit from this natural resource, rather than send it down the curbside drain?

It is possible to further your conviction to live a sustainable life with rainwater collection. The investment can pay off not just for you, your family, and your business, but for all of us who seek to make the best use of rainwater, a vital resource.

Is Rain Collection a Trend?

garden-617272_640The rise of the rain collectors may sound like a scary Halloween prank, but it’s a trend not to be ignored.

According to a recent article published on Earth911, more and more folks, from millennials to baby boomers, are learning how, and then capturing the rain, to mitigate higher water bills and help in conservation efforts, largely due to drought, but also associated to aging infrastructure.

Do you know that by capturing one inch of rainfall from the roof of a 1,000 square foot home, it means you could save up to 312 gallons of water (or what amounts to almost eight, 40-gallon baths).

If you want to know how much rainwater you might collect from your roof runoff, browse to the United States Geological Survey (USGS) rainfall calculator, which can estimate rainfall in areas from a couple square feet to several square miles.

Rainwater collection isn’t only for the home gardener.

Businesses are using collected rainwater for washing vehicles and toilet flushing facilities. Schools are collecting rainwater for community gardens and new multi-family construction could collect rainwater for potable use for tenants or homeowners.

As rain collection trends, it can create a confusing frontier of information and solicitations.

If you decide to have a system professionally installed, we encourage you to know whether or  not your chosen contractor has the accreditation and experience needed for a properly installed, potable or non-potable system. Visit ARCSA (The American Rainwater Catchment Systems Association) to search for a designer and installer with the knowledge and experience to meet your needs.

Workers and Markets Follow the Water

sedge-628370_640The lack of water caused by the California drought affects our food supply in more ways than just the ability to grow crops. It has had deep impact on the workers in this industry and the businesses that employ them. When the cost of water for a 10-acre farm parcel goes from $3,200 to $33,000 in one year, you’ve got a business problem. In 2013, the California agriculture industry employed about 349,000 people.

Currently, the San Joaquin valley is considered the salad bowl of the country. It provides one third of the fruit, nuts and produce we consume in the U.S. With more than 10 years of drought tendency, water has become so scarce and so expensive, landowners are considering what to do next. If the predicted El Nino doesn’t do enough to alleviate the drought situation, workers may have to leave California to follow the water to Washington State. Idaho or Oregon.

Farmers are also learning to become more adaptable and are learning about foreign markets – to maximize their investment in crops by exporting to other countries. China, a large importer of American produce, has become a factor in which crops live or die, because farmers need to consider how to squeeze the most profit out of their products.

“The overseas market is extremely important,” says Jesus Ramos, a farmer who owns 140 acres of mostly citrus trees in Terra Bella in Tulare County. “That dictates whether you can keep a crop going or not.”

California wasteland: Drought-sick farmers hope for relief

California has been experiencing drought conditions since 1999. The lack of rainfall and snowpack in the recent years has pushed farmers in the Central Valley to the edge. Farmers spend millions of their own savings to purchase emergency water to save crops, hoping the coming winter will bring rain to relieve the situation.
