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.
  • chartYou do not need a lot of storage capacity for supplemental use of rainwater. For every inch of rainfall, a thousand square feet of surface will yield 623 gallons of water. 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.

3 Reasons Why Everyone Benefits from Rainwater Collection

1 Comment

20,000 gal residential Bellingham WaAs our population continues to grow in the Seattle and Puget Sound area, demands on our municipal water sources will increase. Costs to repair, upgrade, and expand these centralized systems in order to meet these demands will become more of a challenge.  Here are 3 reasons why everyone benefits from rainwater collection:

  1. Conserves water: 

Rainwater can be collected as a supplementary source or as an alternative to a centralized source. Whether collected rainwater is used for irrigation or potable use, the water savings can be significant for the individual and the community. Over 70 percent of household usage is for irrigation of landscaping, toilet flushing and laundry facility. Depending on collection area and rainfall, whole house demands can be met.

  1. Reduces stormwater runoff:

Stormwater is a concern environmentally as well as economically. The average 2,500 square foot roof in Seattle will yield over 56,000 gallons annually to runoff unless captured and used or infiltrated. Captured rainwater can be used, and then infiltrated passively, rather than carrying contaminants to our lakes, streams, and bodies of water.

  1. Conserves energy:

Any water from a decentralized water system is not processed through a municipal water district where all water is processed to drinking water standards – no matter what its end use will be – such as use in landscaping. Even though a homeowner buys their water for pennies on the gallon, treating water costs a lot of money to process. Most of the costs are absorbed through large users such as manufacturing and farming, however less water being treated at the water districts equals less energy needed for processing and conveyance.

I want to know what you think about how we can all benefit from rainwater collections. Leave your suggestions in the comments section below – or ask me how YOU can benefit from rainwater collection at your home or business.

Will El Nino Bring Drought Relief?

downpour-61916_640California may think it’ll finally see some relief from the extreme drought that has gripped the region for several years because this year’s El Nino is predicted to be massive, bringing heavy rains – and with that the potential of mudslides and flooding in southern California.

CBS/AP reports: “Weather models this year show a 60 percent chance of above-average rainfall in Southern California, but that figure declines farther north…”

There’s a downside. Northern portions of California and parts of Nevada are only looking at between a 50% chance, down to 33% as you head north. Unfortunately, most of the state’s reservoirs are located in the northern portion of California, meaning heavy rains in southern California won’t do much to alleviate drought conditions as its infrastructure is designed to channel rainwater away from homes to prevent flooding – and water is washed out to sea.

The Pacific Northwest is expected to continue being very dry and drought conditions will persist mostly due to warm weather causing reduced snowpack across much of the Cascades Range and Olympic Mountains in Washington. So, while residents and businesses are being diligent about reducing water usage, there is certainly more that can be done on a municipal, county, federal and individual level.
