Don O'Mara — ORC was present during the inspection. The Dunescape Villas WWTF is permitted for 55,000 GPD and consists of: • 6-mm fine screen • 17,950 gallon flow EQ basin • two 17,350 gallon anoxic basins • two 17,350 gallon aerobic basins • two 43,390 gallon sequencing batch reactors (SBR) • 11,780 gallon post flow EQ basin • two Hydrotech tertiary filters • two UV disinfection units • 11,220 gallon anaerobic digester • effluent flow measuring device • 11,970 gallon dosing tank • Disposal via a high -rate infiltration system consisting of three 0.08 acre surface LPP fields. The current facility was constructed and put into operation in July 2017 to replace the old plant. The permit expired on March 31, 2022. A renewal application needs to be submitted. There have been no effluent violations since the last inspection in 2021. A review of groundwater monitoring show some erratic TDS limit exceedances in MW-6 and one isolated Nitrate exceedance in MW-5. The facility is compliant with Non -Discharge Permit WQ0003044. Please review the comment sections of the inspection report for more details.
