Inspection Summary:
A routine compliance inspection of the Summerhouse WWTF was conducted on September 16, 2021. The purpose of the
evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit
WQ0029945. Kary Herndon from ONWASA is the ORC and was present during the inspection. The Division appreciates Mr.
Herndon for his assistance during the inspection.
The facility consists of four Membrane Bio-Reactors (MBR), two of which are in operation, with high rate infiltration for
effluent disposal. ONWASA has the ability to divert flow from the Jenkins Street Pump Station in Holly Ridge to the
Summerhouse WWTF for treatment when needed. Effluent is currently sent to infiltration basin #2. In July 2021, Infiltration
basin #1 was certified for use but has not received flow yet. Signage around the basin is planned for installation before use.
The plant may be decommissioned in approximately 3 years when flow is tied to the Camp Lejeune's WWTF.
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.
In 2021, the facility received 1 NOD for exceedances of daily fecal limits and ammonia limit.
The facility is compliant with non -discharge permit WQ0029945. Please review the comment sections of the inspection
report for more details.
