Rainwater collection tank in Washington DC redevelopment area
Washington DCWater Conservation Tanks
Arris Apartments is a waterfront apartment building with ground-level retail in the Washington, D.C. redevelopment area The Yards. The developer of the apartment building sought a system for rainwater to be collected, disinfected and then used as graywater.
The original specification called for 12-foot-diameter, cladded-steel pipe sections that would be connected and capped in the field. But large-diameter pipes were impossible to incorporate in the limited site space. Instead, we proposed two fiberglass tanks, each with a 20,000-gallon/75,700-liter capacity.
