Description of Process
The Town of Lillington Collection System consists of a combination of gravity and force main lines, Vitrified Clay Pipe 38% (Core
System), PVC 48%, Ductile Iron 12%, Concrete (RCP) 2% and terra cotta are some of the materials used in the construction of the
gravity system (which range from 4" diameter lateral lines, (services) to 21" diameter main lines) We also maintain 6 pump stations on a
daily basis (which range from 2 hp pumps to 45 hp pumps); Currently the average age of the collection system is 60 years old which feeds
directly into the Harnett County Regional Wastewater Treatment Facility, there it undergoes extensive filtration, sedimentation, sludge
removal, and disinfecting before being discharged into the Cape Fear River. The North Carolina Department of Environment and Natural
Resources, Division of Water Quality closely monitors our collection system, the County treatment facility, and the final discharge of
treated wastewater for compliance with Local, State, and Federal regulations.
Performance
The Town of Lillington Sanitary Sewage Collection Department has responded to over 47 residential and 3 commercial blockage
complaints. Several blockages were caused by grease, roots, hygiene products, and food products being introduced into the system.
We have cleaned 21,594 feet of sewer line within the fiscal year.
We have also inspected much of the system and are preparing a report to present to the to the Town Manager which will address the need
for repairing and replacing those parts of the system that are failing due to their age.
We have maintained the integrity of the system according to Local, State, and Federal regulations.

System Improvements 2012 to 2013
The Public Works Department has had the Prison Camp Lift Station replaced and we are currently finishing the force main
connection to the Counties 20" force main from Erwin.
We smoke tested the Prison Camp Sewer Basin and identified many of the previously lost cleanouts.
We had a sewer extension from the Boon Edam plant on McKinney Parkway to the First Choice site completed to serve
development on Autumn Fern Trail.
We have also have had the McKinney Lift Station and numerous manholes throughout the Town relined with Spectrasheild to
extend their life expectancy we started with manholes that have force mains tied into them
Sanitary Sewer Overflows Experienced
The Collections Department experienced 1 Non Reportable Sanitary Sewer Overflow during the past year. With a total of 650 gallons of
untreated sewer reaching the surface this was a non reportable spill.
May 4, 2013: Sanitary Sewer Overflow consisting of 650. With 0 gallons reaching any water source,
Incident Number: Non Reportable
Cause: The cause of the spill was due to debris in the line the debris was determined to be a t-shirt, socks, rags, and diaper wipes all of
which are prohibited items to placed in the collection system.
Corrective Actions Taken: The Public Works Department jetted the line removed the obstructions and cleaned the area of any large
debris we then put dehydrated lime out to absorb any residuals.
***Note — All sanitary sewer overflows have been recorded and reported to the State of North Carolina
Department of Environment and Natural Resources, Water Quality Division.
Reminder
GREASE is an ongoing problem in the collection system. The Town of Lillington currently spends more than $6,500.00 a year to
reduce the amount of grease in the collection system. Contrary to popular belief, running hot water or a type of detergent down the
drain does not lessen the effect grease has when it hardens to the walls of the pipe. Any efforts you as residents can make in reducing
this would greatly help the collection system and reduce the amount of blockages to our customers. Please feel free to contact the
wastewater collection department at [phone] or visit www.lillingtonnc.org if you have any questions or need suggestions on
disposal.
