The City of Jacksonville's wastewater collection system is
composed of approximately 300 miles of sanitary sewer lines and
45 wastewater pumping stations. Twenty pumping stations have
on-site generators to provide power in the event of power failures.
25 of the 45 pumping stations have standby connections, which
allow them to be powered by portable generators during power
outages. In addition, 39 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. (Image-Aerial of the Jacksonville Land Treatment Site)
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.
The 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.
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 flows into an aerated grit and grease removal system where inorganic
material and floating materials are removed. From there, wastewater move into a series of aerated lagoons where
biological treatment of the waste occurs.
Secondary treated wastewater flows into storage lagoons where it is held for irrigation. Storage lagoons have a 690
million gallon capacity, provides storage of treated wastewater during periods of inclement weather and when spray
irrigation is not feasible. Treated wastewater is chlorinated to eliminate harmful bacteria and then used to irrigate 2,300
acres of pine forest on the LTS property.
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 the Chief Operator,seven Wastewater Plant Operators,three Plants Maintenance
Mechanics, one Plants Maintenance Worker, a 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 2,127 million gallons of wastewater during the 2020 calendar
year, at an average daily flow of 5,810 million gallons. Hurricane Florence effected the City of Jacksonville on September 12, 1
2018. During 2018, record rainfall of more than 100 inches increased irrigation and storage lagoon levels at the facility. To
maintain the permitted freeboard level of 2.0 feet, City staff followed the guidelines of the Emergency Action Plan required
by its permit and implemented emergency irrigation on December 17, 2018. Through notification and discussions with North
Carolina Department of Environmental Quality(NCDEQ) Wilmington Regional Office emergency irrigation at the facility ceased
on October 7, 2020.
At no time during the calendar year of 2020 did the facility violate the freeboard level of 2.0 feet. In accordance with the
permit, City laboratory staff collected surface water samples as stipulated by the guidelines of the City's Emergency Action
Plan. There were no negative findings in any of the surface water samples collected. As a result of emergency irrigation, the
City exceeded the annual hydraulic loading rates in multiple blocks during 2020. By June 2020, all annual hydraulic loading
rates were within permitted limits. The City of Jacksonville is actively working in conjunction with the NCDEQ Wilmington
Regional Office to re-evaluate the permitted annual hydraulic loading rates to ensure that the facility continues to operate
efficiently.
No other monitoring or reporting requirement violations occurred during the 2020 calendar year.
III. Collection System Performance i
There were fourreported overflows from the collection system duringthe 2020 calendaryeargreater than gallons
(4) p Y 1,000I
in volume. The locations with overflows that exceeded 1,000 gallons were as follows:
• January 7, 2020: Wardola Culvert Bridge that crosses over East Thompson School Creek. A sewer force main was hit
by a contractor who was hired by the City to replace the culvert bridge. Approximately 3,000 gallons of untreated
wastewater was estimated to have spilled with 2,000 of those gallons estimated to have reached East Thompson School
Creek. None of the wastewater was able to be recovered. The force main has been repaired.
• April 20, 2020: 807 Huff Drive (manhole #5068) approximately 10,080 gallons of untreated wastewater was spilled into
a ditch that leads to Northeast Creek. A piece of concrete was found in the line, which caused a buildup and resulted
in the wastewater overflow. An emergency environmental contractor was hired and the City recovered 2,850 gallons of
the untreated wastewater.
• November 17, 2020: Manhole at Brenda Drive and Onsville Drive (manhole #2824) approximately 10,623 gallons
of untreated wastewater was spilled into a nearby stormwater ditch. A dam was built to stop the flow of untreated
wastewater in the stormwater ditch. An emergency environmental contractor was hired and they were able to recover
10,553 gallons of untreated sewer water. 70 gallons of untreated sewer water was not able to be recovered. A broken
sewer line caused the spill. This sewer line has been repaired.
• November 19, 2020: 106 Fairway Road (manhole #24) approximately 2,510 gallons of untreated wastewater was
estimated to have spilled. 710 of those gallons was estimated to have reached Sandy Run Branch. A buildup of rags and
grease in the sewer line caused the spill.
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 saw excellent performanc during 2020. Total rainfall for
2020 was 73.4 inches at the Administration Building of the Land Treatment Facility and the total influent and effluent for 2020
was 2,127 million gallons and 1,744 million gallons, respectively. The City replaced 83 linear feet (LF) of 12-inch sewer pipe during
2020. In addition, new sewer projects totaling 568 linear feet (LF) of 8-inch pipe were added during 2020. 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 196 establishments with grease interceptors that must be cleaned every 30 days. They are also regularly inspected to ensure
compliance. In addition, the City cleaned 168,455 linear feet(LF)of sewer pipe in the collection system during 2020. Lastly,the City
has a program that evaluates and replaces pumps in wastewater stations that fail or are over 20 years old.
