What is Your Water Consumption Footprint?

tap-357252_1280

The average American has a water consumption footprint of 2,220 gallons per day. What’s yours?

By now, most of us are aware that California is in the midst of a marathon drought. While you may live in an area with an abundant amount of water, we must realize that it is a valuable resource, one that we cannot live without and, evidenced by the drought in California, it is a limited resource.

A recent article in Grist compares the lack of water use consumption reduction in California to the stages of grief. While Californians have been directed by the Governor to reduce water use by 25%, the real numbers only add up to an 8.6 reduction statewide, potentially triggering Stage 2 – Anger.

The point this writer found interesting was that there is a difference between telling folks to conserve and reduce water consumption, than SHOWING them how.

A good place to begin learning how to conserve water is to know how much water you and your family or business consumes daily, weekly, monthly and annually. It’s not a matter of knowing how much water flows from your faucets or goes down the drain when you do laundry. It’s about the food you eat (do you eat meat, or are you vegetarian or vegan?), the appliances you use (low flow faucets and toilets) and whether you take baths or showers.

CityLab offers a calculator which “reminds us that every bite of food, every mile we drive, and every light switch we flip relies on the wet stuff.”

Many of us underestimate how much water we actually use day-to-day, and year-to-year. A good deal of this underestimation stems from our neglect to account for water used to process our food and send electricity to our homes. Take a few minutes to see what your water footprint looks like and learn ways you can help conserve this vital, limited resource.

Project Update: Two Sole Source Potable Rainwater Systems

Index tank _bridgeRainBank Rainwater Systems was contracted to install a 10,000 gallon, sole source, potable rainwater catchment system in Baring WA,  just east of Index. The system was designed by Chris Webb, PE of Herrera Environmental Consultants for a single family dwelling. The system will provide potable whole house usage as the only source of water for this 839 square foot home. With  41.2″  annual rainfall, the system is capable of supplying 100% of the household demand based on occupant’s usage requirements.

The small parcel size and the small bridge over the Skykomish bridge limited the feasibility of safely drilling a well and there is no public or community water system. RainBank Rainwater Systems always enjoys a challenge – and this one has many – from a very small lot with wetlands, large boulders throughout the property, the bridge, and location of site

Skagit TanksRainBank Rainwater Systems has recently begun construction of another 10,000 gallon, sole source, potable rainwater collection system in the Skagit River Basin, which has been affected by the in stream flow rates, along with a well drilling moratorium. The system was also designed by Chris Webb and Herrera Environmental Consultants for a single family dwelling. Again, the system will provide whole house potable water as the only source of water. The house is 3500 square feet, so 33.2″ annual rainfall  will meet the daily demand for 95% of the days in this model with no change in use. The reality is, that the occupants would decrease usage during times of drought and therefore the 2 – 5,000 gallon cistern volume is considered capable of supplying 100% of domestic use.

The Cost of Seattle Water

The Cost of Seattle Water

The Seattle water system is a good one, provided by Seattle Public Utilities. But, as the demand grows with urban development and population, the cost of Seattle water will need to rise to support expansion.

A recent article by Gene Balk in the Seattle Times makes some interesting points.  Balk mentions “…bafflingly — drought-stricken Fresno, Calif., has some of the cheapest water in the nation. At a 50-gallon-per-person usage, a family of four would pay just $41.63 — less than one-quarter of the cost in soggy Seattle.”

Balk goes on to write: “Seattle has such high rates because we’ve invested more than most places in our water infrastructure in recent years. We relocated our reservoirs underground, in compliance with federal mandates, to keep our drinking water safe from contaminants. “

We can clearly see that it’s not the amount of Seattle water that is the generator of costs, it is the infrastructure required to convey and treat the water to potable standards.

Approximately 70 % of household water demand is for non potable usage. Irrigation, water closets, laundry, and wash down account for this non potable use. Rainwater collection can mitigate non potable use of city water and have a positive effect on our centralized water system and environment.

The commercial building owner and the home owner can enjoy healthy savings on future Seattle water bills by utilizing rainwater collection. Stormwater reduction could be significantly recognized through on site filtration if buildings and homes in the urban environment adopted rainwater collection .

Seattle is a progressive city in many ways and rainwater collection is part of that progression.
