Inspection Summary:
A routine compliance inspection of the Summerhouse WWTF was conducted on May 02, 2019.The purpose of the
evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit
WQ0029945. Mike Lutz, ORC,and Eddie Caron, ONWASA's Utilities Superintendent,was present during the inspection.
This facility started up in the spring of 2017 after extensive repairs and equipment replacement.Two of the four Membrane
Bio-Reactors(MBR)are in operation. Currently,the facility is treating an average of 87,000-88,000gpd of the 400,000gpd
permitted flow. Effluent disposal consists of two infiltration basins located within the Summerhouse community. Infiltration
Basin#2 is currently being used while Infiltration Basin#1 is waiting on work to begin in the near future to increase the
hydraulic loading rate. Staff keeps organized records to include daily/weekly task check sheets, monthly data computer
spreadsheets and a detailed operation/maintenance log book to monitor plant operations. ONWASA has the ability to divert
flow from the Holly Ridge, Jenkins St. Pump Station to Summerhouse WWTF for treatment instead of going to Holly Ridge
WWTF.
Since start-up,the facility has had 4 daily fecal limit NODS, 1 daily ammonia limit NOD and a NOV for a monthly total
phosphorus limit issued.There has been complaints from the residents of the Summerhouse community about the algae
growth that can be seen in the summer months in the infiltration basins. ONWASA has communicated to the residents the
nature of algae growth and has contacted our office for assistance in the past.
The facility is compliant with non-discharge permit WQ0029945. Please review the comment sections of the inspection
report for more details.
