Inspection Summary:
A routine compliance inspection of the Town of Oak Island Collection System was conducted on February 12, 2020. The
purpose of the evaluation was to verify that the system is operating in compliance with the conditions and limitations
specified in Permit WQCS00334. Mark Moore, Ronald Shannon and Bobby Cain were present during the inspection.
The Town of Oak Island Collection System consists of nine vacuum stations and thirty-three pump stations that collect and
send flow to the Town's wastewater treatment facilities, Fish Factory WWTF or the Satellite WWTF, or to the West
Brunswick WWTF located off the Island. During the summer season, the flow through the collection system can average
around 8,000,000 to 9,000,000 gpd.
The Town's staff seems very knowledgeable about the operation of the vacuum system and the entire collection system
appears to be well maintained. A consultant from the vac system manufacturer evaluates the system annually to address
any issues. Two pass pumps for the larger lift stations and vac stations have been purchased. The Town has been working
towards installing by-pass connections at all the pump stations. There are odor control systems installed at all the vacuum
stations and a Bio-Trickling filter odor control system in place at the Middleton/Vac Station #5. Middleton station also has
chemical addition for corrosion and odor, before it is pumped to the West Brunswick WWTF. The Town has developed a
Hurricane Valve Shut Down Plan in preparation for hurricane/tropical storm weather to quickly and efficiently shut down the
vacuum system to decrease damages.
The Town of Oak Island is compliant with collection system permit WQCS00334. Please review the comment sections of
the inspection report for more details.
