Inspection Date: 01/27/2023 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
An inspection of the Southwest Plantation Wastewater Treatment Facility (WWTF) reclaimed water generation and
non -conjunctive reclaimed water utilization system, Permit Number W00029601, was performed on January 27, 2023, in
order to verify compliance with the existing permit. Charles ("Sonny") Scozzari, (system contract ORC) was present and was
very helpful in assisting during the inspection.
The system is permitted for the operation of a 250,000 gallon per day (gpd) reclaimed water generation and non -conjunctive
utilization system which was proposed in three (3) phases (i.e. Phase I, II and III). Currently Phase 1 (50,000 gpd) is
constructed and operated and includes:
• Manually cleaned bar screen with 1" spacings
• A 15,000 gallon aerated Flow Equalization Basin with bubble diffuser system
• Two 7,888 gallon aerated Sludge Holding Basins with bubble diffusers
• Two (2) 25,582 gallon Aeration Basins with bubble diffusers
• Two (2) 4,170 gallon hopper bottom Clarifiers
• Tertiary Treatment unit
0 3,145 gallon wastewater chamber (aka mudwell)
o Dual media filter
0 3,030 gallon clearwell with and an effluent flowmeter
o A 1,600 gallon post aeration chamber with UV disinfection unit with 24 lamps
• A 258,3657 gallon synthetically -lined five day upset pond
• A turbidimeter, a rain sensor, telemetry and a permanent auxiliary power source.
• 2.5 MG reclaimed water storage pond
• Approx. 50.32 acres of spray irrigation area on the golf course and driving range.
The facility is deemed compliant with Permit WQ0029601. Please review the comment sections of the inspection report for
more details.

The 5-day upset pond was very low and had ample freeboard and the irrigation pond had
slightly less than 3 feet of freeboard. Both ponds appeared well maintained and re -use signs
were observed at the irrigation pond. Signage indicating use of reclaimed water should be
posted at the golf course club house.
