Findings during the inspection were as follows:
At the time of inspection, required logbook, maintenance and ORC records, irrigation
calibration records, spill prevention plan, residuals management plan, annual standard soil
fertility analysis, NDMR and NDAR-1 records were submitted as required and available for
review. All records were organized and available for a period of five years. The overall
condition and integrity of the wastewater system and facility grounds were properly
managed. At the time of inspection, the ORC was on -site and gave a comprehensive tour of
the treatment system and its components.
The membranes are back pulsed as required based upon a pressure increase and the
decrease in flux from the system. The reject waters are returned to the influent basin.
The facility grounds and lagoon perimeter were securely fenced with proper signage and
the liner was clean and in good condition. The freeboard level was clearly delineated with
67" of available volume.
Meritech laboratory draws effluent samples for analysis. No discrepancies in the data were
noted and the facility is drawing the required samples at the frequency required by the
permit. Influent and Effluent flows are recorded from in line magnetic meters.
Maintenance activities are recorded weekly and monthly for all service equipment and
facility grounds. A moisture sensor and visual/audible alarm is located at the pump house
with the control panel. Effluent discharge to the spray field is controlled by A VFD and
flow/duration are data logged and recorded each spray event per zone selected. The spray
field was well maintained, secured with proper signage and good condition with no signs of
ponding.
Residuals from the facility are documented and removed from the facility as required by
Granville septic and transferred to the Warren County WWTF for disposal.
Annual standard fertility tests are conducted through NCDA&CS Department of Agriculture.
All metering equipment and calibrations are conducted through Chadwick
Instrumentation.
The system has an integrated auto dialer for mechanical and/or emergency callout
response. The on -site backup generator auto cycles each Monday and is maintained with a
service contract annually.
