The City of Jacksonville's wastewater collection system is composed of sanita sewer
lines and 45 wastewater pumping stations. Twenty-six of these pumhgenera.ors to
provide power in the event of power failures and 16 of the pumping statio, which allow
them to be powered by portable generators during power outages. In addition, 37 of the pumping stations also
have bypass connections that allow the use of portable bypass pumps that will redirect water flow if a power outage
occurs. The City currently owns 5 portable generators and 3 portable bypass pumps.
The City's Utilities Maintenance Division staff consists of 29 employees and is responsible for maintenance, repair
and the proper functioning of the sewage collection system and the maintenance and efficient operation of the
wastewater pumping stations. This Division provides routine inspections of the City's manholes and is responsible
for jetting sewer lines to clear blockages. This staff also provides preventive maintenance to all the wastewater
pumping stations and generators to ensure optimum operation. A section within the Division is responsible for
ensuring all privately owned grease traps are maintained within the City ordinance requirements. The Utilities
Maintenance Division also has an Inflow & Infiltration (I&I) Analyst on staff to identify, document, and reduce inflow
and infiltration into the City's collection system.
The Jacksonville Land Treatment Site (LTS) totals 7,400 acres of land and is responsible for the treatment and
land application of the City's wastewater. The system is presently designed to treat 9.0 million gallons of wastewater
daily via spray irrigation of 2,300 acres of primarily loblolly pine trees. Wastewater is transported 8 miles from
Jacksonville to the LTS by a 36-inch diameter force main. The wastewater is treated with hydrogen peroxide for
odor removal prior to flowing into the headworks facility. At the headworks facility, the influent (raw wastewater)
passes through dual Huber Step Screens where material greater than 1/8 inch in size is removed. The wastewater
then flows into an aerated grit and grease removal system where inorganic material and floating materials are
removed. From there, wastewater flows into a series of aerated lagoons where biological treatment of the waste
occurs. Secondary treated wastewater then flows into storage lagoons where it is held for irrigation. The storage
lagoons have a capacity of 690 million gallons and provide storage of treated wastewater during periods of inclement
weather and when spray irrigation is not feasible. The treated wastewater is chlorinated to eliminate harmful
bacteria and then used to irrigate 2,300 acres of pine forest on the LTS property.
The irrigation fields have three classifications of soil types: Well -drained, Moderately Well -drained, and Seasonally
Suitable. These irrigation fields are divided into 28 blocks and the annual hydraulic loading for each block is a
permitted maximum ranging from 49.0 to 62.6 inches/acre, depending on the relative percentage of each soil type.

As the pines mature and their ability to store nutrients decreases, the mature trees are harvested and used for pulp
wood. Young seedlings are planted to repeat the cycle.
The Land Treatment Facility is staffed by one Plant Superintendent, one Lead Operator, six Wastewater Plant
Operators, three Plant Maintenance Mechanics, one Plant Maintenance Worker, one Crew Leader, and three
Equipment Operators. The Laboratory Section is also housed at the LTS and is staffed by the Supervising Chemist,
assisted by two Laboratory Technicians, who performs all the required analyses and is responsible for the
certification of the wastewater laboratory.
II. Facility Performance
The City of Jacksonville's Land Treatment Facility treated 1,517 million gallons of wastewater during the 2022
calendar year, at an average daily flow of 4.2 million gallons. The City was in compliance with all monitoring and
reporting requirements during the 2022 calendar year.
III. Collection System Performance
There was one (1) reported overflow from the collection system during the 2022 calendar year greater than
1,000 gallons in volume. The locations with overflows that exceeded 1,000 gallons were as follows:
• August 21, 2022: 1364 Lejeune Boulevard (manhole #5135) approximately 3,900 gallons spilled. We
recovered all with the exception of approximately 600 gallons. The SSO was due to debris in the line segment.
It was removed and the line was cleaned.
The City maintained constant communication with NCDWQ after each of these events to ensure full compliance
with Environmental Laws and Regulations. The City continues to identify and remediate inflow and infiltration, as
well as rehabilitate wastewater infrastructure to prevent further overflows.
IV. Summary
The City of Jacksonville's Land Treatment Facility and collection system performed excellently during the calendar
year 2022. The total rainfall for 2022 was 50.2 inches at the Administration Building of the Land Treatment Facility
and the total influent and effluent for 2022 was 1,517 million gallons and 1,251 million gallons, respectively. The
City replaced 518 linear feet (LF) of 8-inch sewer pipe and 652 linear feet (LF) of 12-inch sewer pipe during 2022.
The City has ongoing maintenance programs to ensure the wastewater collection system continues to function
effectively. The City utilizes cured -in -place lining, point repairs, and manhole lining to reduce or eliminate inflow
and infiltration. Other measures include the rain stopper program, fats, oils, and grease management, and pump
station maintenance. The rain stopper program is a continuous effort to insert rain stoppers in manholes to prevent
or minimize overflows when heavy rainfall occurs. The Fats, Oils, and Grease (F.O.G.) Management Program
attempts to mitigate blockages and other issues through ordinances, grease interceptors, cleaning and
maintenance, as well as education and awareness efforts. In Jacksonville, there are 252 establishments with grease
interceptors that must be cleaned every 30 days. They are also regularly inspected to ensure compliance. In
addition, the City cleaned 184,415 linear feet (LF) of sewer pipe in the collection system during 2022. Lastly, the
City has a program that evaluates and replaces pumps in wastewater stations that fail or are over 20 years old.
