FWRC 2023 – H2YOU! – Facility Tour –
Conference Attendees Tour Hamlin Water Reclamation Facility On Wednesday, May 31, conference attendees had the opportunity to tour the Hamlin Water Reclamation Facility, which resides on 50 acres in the Horizon West/Winter Garden section of Orange County and has a permitted treatment capacity of 5 million gallons per day. This advanced domestic wastewater treatment facility currently treats a daily average of 3 million gallons and serves approximately 40,000 people. The operating permit represents the first of three construction phases, and initial treatment of flows began in October 2022. Wharton-Smith provided general contracting services for the $110.6 million project. The project consists of a new pretreatment structure with an odor control system, process air blower system and blower building, secondary clarifiers, return activated sludge and waste activated sludge pump stations,
tertiary cloth filtration, chlorine contact tanks, effluent transfer pump station, reclaimed water storage tanks, reclaimed water/nonpar water high-service pump station, sodium hypochlorite storage and feed systems, reject pond system, covered sludge holding tanks, gravity belt thickening equipment in an associated metal building, electrical gear and emergency power generators with a fuel storage system, and administration and maintenance buildings. The facility uses a five-stage Bardenpho-type process that includes screening, odor control, grit removal, aeration with nitrification and denitrification, secondary clarification, supplemental chemical feed (if necessary), disk filtration units, and chlorination. Biosolids are processed through gravity belt thickening equipment and stored in holding tanks for
