Subject: Compliance Evaluation Inspection
Town of Warrenton Sewer Collection System
Collection System Permit No: WQCS00092
Warren County
Dear Ms. Valentine:
On May 23, 2018, Cheng Zhang of the Raleigh Regional (RRO) Office Division of Water Resources
conducted a Compliance Evaluation Inspection of the subject facility. The assistance and cooperation of
Mr. Bill Perkinson, the Director of Public Works and Operator in Responsible Charge (ORC), and Mr.
Oscar Davis, the Backup ORC during the inspection, were very helpful and appreciated. A checklist of
items is enclosed with this letter. During the inspection the following items were noted:
1.) The Town's collection system is classified as a Class 2 collection system. It has approximately 21
miles of gravity sewer mains, 7 miles of force main, and 4 duplex pump stations. Mr. Bill Perkinson
is the Operator in Responsible Charge (ORC) and Mr. Oscar Davis, Mr. and Mr. Kenneth Champion
are the backup ORCs. Please contact the Division to update the list of operators, since contract
operators (from Envirolink) no longer operate the collection system.
2.) The Town has a developed and maintained a collection system map which has all items required by
the permit. A GIS based collection system map is being developed.
3.) The Town has developed and implemented a Capital Improvement Plan (CIP) for the sewer system,
which includes all components required by the permit. Current CIP covers a ten-year period (2011 to
2021), with total sewer capital improvement budget of$1,458,894.
4.) The system has 4 duplex pump stations. All four pump stations were visited during the inspection. It
is recommended that backflow devices be installed at the two pump stations with water line to
prevent contamination of the potable water (see comments in Inspection Report).

quarterly. Grease educational flyers are sent to customers with water/sewer bills semi-annually.
6.) A review of records and logbooks indicate the following
a) Records are maintained adequately for sewer line maintenance, cleaning, high priority line
inspection, and right of way maintenance. The record keeping is excellent.
b) 5 Sanitary Sewer Overflows (SSOs) were discovered or reported since the last inspection.
7.) Three aerial lines were observed during the inspection, these lines were in good condition, to which
the right-of-way was maintained.
