Turkish Bath Becomes Rainwater Collection Cistern

mosaic-200864_640With a little bit of creative thought, Tacoma, WA set out on a path of  green capability while reclaiming a downtown area that had become degraded and mostly abandoned – partly using a Turkish bath.

In an article from Environmental Protection Online, we learn how the city of Tacoma repurposed  Park Plaza South. During the reconstruction, an old Turkish Bath was uncovered. Cleverly, the designers decided to use the old bath as a rainwater collection cistern, which would collect water to be used for irrigation and toilet flushing.

“Other sustainable features at Pacific Plaza include 36 percent of the building materials being recycled, from structural steel and panel metal sidings to wood and windows. All of the products used met LEED (Leadership in Energy and Environmental Design) thresholds for low-emitting materials, while interior materials such as carpet, flooring, paint, and composite woods had low levels of volatile organic compounds.

These features, along with the rainwater collection system, earned the building a NAIOP Sustainable Development Award and LEED Platinum certification from the U.S. Green Building Council. While the Platinum certification was the city’s first, there now are more than 25 local businesses, schools, or housing complexes that are silver or better LEED-Certified in Tacoma, with many more in the works.”

How Rainwater Collection Protects Water Supplies

Federal Way Washdown_RainBankLLC_webCan Rainwater Collection Protect Water Supplies?

As mentioned in Ken Blair’s previous article, rainwater collection for residential and commercial construction helps protect our water supplies by using rainwater for irrigation, toilet facility, and other uses.

For example, the city of Federal Way, WA uses a rainwater collection system for its school maintenance facility. It collects rainwater for washing  its school bus fleet, and during the summer, the collected water is used for irrigation.

In Harvesting Nature’s Supply, ARCSA (American Rainwater Catchment Systems Association) board member, Neal Shapiro writes about a city library using rainwater collection for toilet flushing, Santa Monica’s first municipal building to implement rooftop rainwater harvesting for indoor use.

Shapiro, watershed management program coordinator for the Office of Sustainability and the Environment for the city of Santa Monica, CA, goes on to document the library’s rainwater harvesting system, showing  how rainwater can be collected on site for non-potable use in a commercial setting. This approach promotes the use of “local water resources and local self-sufficiency; reduces dependence on imported potable water, which benefits distant watersheds by keeping more water there; and reduces negative impacts from stormwater, which carries numerous pollutants to Santa Monica Bay”.
