Everglades Stormwater Treatment Area 1-West Expansion

The South Florida Water Management District (SFWMD) needed to expand their environmental protections for the Arthur R. Marshall Loxahatchee National Wildlife Refuge and other parts of the greater Everglades. They reached out to us for help. Our team’s work is one of many critical restoration projects that SFWMD is developing for treating stormwater to meet effluent quality standards that comply with the State of Florida’s numeric phosphorous criterion in the Everglades.

Looking to expand and enhance Stormwater Treatment Area 1 (STA-1), we designed the 4,700-acre (1,900-hectare) constructed wetland expansion to the west of STA-1. Our design features 100,300 linear feet (lf) of earthen embankment and 85,600 lf of canals, nine remotely operated gated hydraulic structures including 25 roller and slide gates, 20 passive hydraulic structures, and constructed wetlands. Three wetland cells create flexibility, allowing portions of the system to be taken offline for maintenance and vegetation management while keeping the rest operational.

As one of many critical restoration projects that SFWMD is developing, this rejuvenated area of the Everglades also provides public recreation opportunities and habitat for threatened and endangered species.
