CERP Project:
Winsberg Farm Wetlands Restoration

The project involved restoration of approximately 114 acres of wetlands on former agricultural lands. Wetlands would reduce the amount of treated wastewater coming from the Palm Beach County's Water Utilities District (PBCWUD) Southern Region Water Reclamation Facility (SRWRF) lost to deep injection wells by further treating and recycling the water. Treated wastewater will instead be reused to recharge the local aquifer system, create a new ecologically significant wildlife habitat and extend the function of the nearby Wakodahatchee Wetland. The initial configuration would include a Phase 1 design and construction with approximately 72 acres of wetlands created in the western half of the project. The remaining 42 acres of the project on the eastern half, considered Phase 2, would work similarly. As a result of the real estate purchase agreement (175 acres) made in 2003 between PBCWUD, the non-federal sponsor, and the Winsberg family, PBCWUD completed construction of Phase 1 in 2004. It included 72 acres of wetlands, plus a parking lot, visitor center, and recreational access features and was completed without Federal funds. The local sponsor refers to this portion of the project as "Green Cay Wetlands".

The Tentatively Selected Plan (TSP) identified in 2005 and presented at AFB, is configured assuming constant inflow of water to maintain continuous inundation. Refinements during the formulation process provide for the project to be located on approximately 165 acres of farmland just east of the Southern Region Water Reclamation Facility (SRWRF). Approximately 114 of the 165 acres would be hydrated using treated wastewater from the SRWRF resulting in the creation of a wetland system approximately three times the size of the adjacent Wakodahatchee Wetlands, and its location and proximity would leverage the recently created ecosystem restoration benefits by expanding the constructed wetland into an integrated system having even greater regional significance. Water levels will be allowed to fluctuate seasonally, within a 1- to 2-foot range throughout the entire project, in response to the natural seasonal variation of rainfall. This variation in the depth of project hydration will influence the growth and distribution of various plant species within the wetland area.

Effluent enters the site from the western half of the project (Phase 1). To circulate flow throughout the project, several control structures and pumps would be integrated in various locations and can be operated to allow flow in three ways:

  1. To the eastern half of the project (Phase 2), or

  2. Circulate flow in the eastern half of the project by a 15-hp recirculation pump, or

  3. Send flow to deep well injection by a 250-hp discharge pump in the event pool elevations rise beyond a set point due to direct rainfall.
