Inspection Summary:
A routine compliance inspection of the ONWASA Collection System was conducted on August 19, 2020. The purpose of the
evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit
WQCS00249. Justin Sanderson, ORC, was present during the inspection. This inspection covered the Holly Ridge area of
the collection system and did not cover all the required documentation.
ONWASA operates 13 pump stations in Holly Ridge. The Green Street PS has not received any flow to date, and a new
pump station is currently being constructed at the future Homestead Place Subdivision. Nine pump stations were inspected
and all were well maintained. Inspection and maintenance log books were complete and stored at each pump station.
ONWASA plans on using the Survey 123 program on tablets to replace the paper logs soon. This will allow them to issue
work orders faster and more efficiently. ONWASA is also working towards using their GIS mapping system to map work
orders, lines cleaned, CCTV inspections etc.
ONWASA is compliant with collection system permit WQCS00249. Please review the comment sections of the inspection
report for more details.

Comment: All of the Hollv Ridae DumD stations are connected to a Mlssions SCADA system. By the end of
the year, ONWASA plans on connecting the small number of pump stations throughout the entirE
system that still have a chatterbox with the Missions system. Generators are auto tested and
manually tested weekly. Generator preventative maintainence is performed once a month by
staff and once a year by a contracted company. Pump station inspection and maintainence logs
are complete and stored at each pump station. Staff removes grease and cleans the pump
stations monthly. The audio alarm at Summerhouse PS #4 was not operable and needs to be
repaired.
