I. General Information
Name of Regulated Facility
Town of Liberty
The Town of Liberty is permitted through the State of North Carolina to operate a spray
irrigation wastewater treatment facility and operate the wastewater collection system.
Responsible Persons
Elix T. Fike is the treatment plant operator responsible in charge (ORC).
Kevin Coble is the collection system operator responsible in charge (ORC).
Scott Kidd, Town Manager is the responsible person for the Town of Liberty facilities and can be
contacted at [phone].
Permit Number
Wastewater Treatment Facility Permit Number: WQ0003090
Wastewater Collection System Permit Number: WQCS00280.
The wastewater treatment facility is a spray irrigation system located at 7178 East Highflll
Avenue. The treatment process consists of a manual bar screen, a lagoon, chemical treatment,
and effluent pump station. The Town is permitted for 550,000 gallons per day of sewage. The
sewage enters the plant and goes through the bar screen which removes all solids. The solids
are removed and disposed of by Allied Waste. The flow then proceeds to a three (3) pump
influent station that pumps the sewage to the lagoon. The lagoon is a natural occurrence system
that separates the remaining solids from the liquid. The solids settle to the bottom of the lagoon
with the water staying to the top. After a 88 day detention time, the water is then treated with
chlorine to remove all fecal coliform bacteria. The next process is to spray the effluent onto the
spray fields. We maintain one hundred eighty (180) acres of spray fields. The spray fields are
broken down into eight (8) zones. The Town of Liberty contracts the cutting and removal of the
fields for hay.
The Town of Liberty collection system consists of approximately 23 miles of sewer lines. The
lines vary in size from four (4") inch to twenty four (24") inch in diameter. The collection
system also consists of eight (8) lift stations that carry the wastewater to the treatment facility.
Operators make daily checks on the outfall lines and lift stations. The public works crew along
with contracted maintenance is responsible for the mowing and clearing of the outfall lines for
easy access in case of any emergencies.

II. Performance
The Town's most recent Compliance Evaluation Inspection of the Wastewater Treatment Plant
was July 20, 2023. The inspection mostly reflects compliance with Permit No. WQ0003090.
All items continue to be monitored by the ORC.
It is our goal to continue to find ways to improve the operations of the Wastewater Treatment
Facility and Collection System as we go forward.
