Build a Grattix in an afternoon!

November 1, 2019 @ 12:00 pm - 4:00 pm

ECOSS and Equinox Studios invite you to Learn and Do!

Come learn how to make a Grattix box downspout filter to reduce water pollution. Then help construct a Grattix box and install it under a roof downspout. Grattix boxes and other roof downspout filters bring the benefits of rain gardens to paved areas at homes and businesses and can work in small spaces. The design is particularly effective for removing zinc from galvanized roof surfaces.

Tools and refreshments provided.

In 2018, ECOSS partnered with Equinox Studios to develop a first of-its-kind, large-scale industrial GSI demonstration site. The site, now building Phase 1, will showcase new and emerging industrial GSI solutions that can be adopted by any industrial or manufacturing business. When finished, Equinox GSI will collect stormwater from 62,000 square feet of roof space and passively filter 1.3 million gallons of water annually.

For more information, or to schedule a site visit or tour, please contact at info@ecoss.orgor (206) 767-0432, ext. 1001.
