Wilson Creek Wastewater Treatment Plant Upgrade
Greenwood Metropolitan District (GMD), a non-profit agency providing sewer and reclaimed water services, required design and plant upgrades to their existing Wilson Creek Wastewater Treatment Plant (WWTP). In order to complete the project, GMD engaged Davis & Floyd to design, bid, and oversee construction of all phases of the upgrades.
ACEC-SC Engineering Excellence Award for Phase 1B
Prepared Preliminary Engineering Report (PER) to investigate options and develop cost estimates
Constructed two 135-foot-diameter clarifiers and new RAS/WAS pump station, a 40.0-MGD influent screening and pumping station, grit removal system, two 6.0-MGD BNR systems, two 135-foot-diameter clarifiers, ultraviolet disinfection system, and effluent flushing water system
Renovated administration building
Upgraded emergency power for the plant
Installed advance cloth membrane filtration technology
Previous plant additions resulted in the WWTP operating beyond its hydraulic capacity
Nitrogen and phosphorus limits were susceptible to future regulatory changes
A successful upgrade project that fitted WWTP with the latest technologies to accomplish biological treatment of the waste stream under more stringent regulatory requirements.
