Description of Collection and Treatment Systems:
Operation and maintenance of a wastewater collection system consisting of, at the time of permit issuance,
approximately 28.4 miles of gravity sewer, approximately 6.5 miles of force main, 17 duplex pump stations, all
associated piping, valves, and appurtenances. Serving 1,037 customer connections.
Operation of a 0.360 million gallon per day (MGD)wastewater treatment system utilizes the following
components: Vertical fine screen and auger, influent lift station, 2 aeration basins, clarifier, equalization basin,
digester, 2 cloth media filters, 2 Ultraviolet disinfections units.

1. Bar Screen—Removes larger debris that can potentially damage equipment such as rocks and sticks.
2. Liftstation—Pumps all incoming wastewater to the beginning of the treatment plant
3. Aeration Basin—Air is circulated,and the bacteria remove dissolved solids,pollutants,Phosphorus and Nitrogen.
4. Clarifier—Solids are separated from the liquid and piped back to the aeration basins via the return activated sludge piping.
5. Equalization Basin—Allows for a steady and consistent flow of wastewater through the plant.
6. Filters—Liquid is filtered to remove any remaining fine particles.
7. Disinfection—Effluent is disinfected by ultraviolet light to inactivate pathogenic organisms.
8. Digester—Treats the solids removed from the wastewater to allow safe and economical disposal.

Summary of Collection System Performance:
During 2021, we collected and treated over 77 million gallons of wastewater. In addition, twelve (12)
manholes were repaired to address leaks that were discovered during routine inspections.
The collection system experienced one (1) sanitary sewer overflow during 2021. Our staff is committed to a
standard of excellence by ensuring a safe and clean facility while maintaining regulatory compliance. No
known adverse effects have been noted on the environment or receiving streams.
Key Performance:
• 15,280 linear feet of the sewer collection system was clean during 2021.
• There are 17 duplex Lift Stations serving Connestee Falls Subdivision. Each lift station is checked three
times a week with maintenance conducted as needed as well as emergency generator testing, wet well
cleanings, and emergency/routine repairs conducted periodically.
• Annually each Lift Station is inspected using our 56 Point safety checklist.
• As part of our Asset Management Program, an Annual Maintenance Checklist is conducted to
determine that equipment is performing at peak efficiencies.
• Our staff throughout the year manually conducts manhole inspections and documents deterioration (if
any) due to corrosive atmospheric conditions.
• We have instituted an infiltration and inflow (I&I) program. The purpose of the I&I program is to keep
unwanted storm water from entering the collection system. Infiltration and inflow is a clear indicator
that there could be broken pipes, uncovered sewer laterals, or someone illegally connected to the
collection system.
• As a proactive measure, we educate our customers of our concerns of Fats, Oil, and Grease. Your help
in what is put down the drain greatly prevents clogs due to grease buildups and improves our overall
collection system. These grease buildups can result in SSO's.
• Our staff is continually monitoring and clearing rights of way (ROW's). These ROW's normally are in low
lying creeks and wooded areas. ROW's need to be cleared to ensure easy access during emergency
situations.
Summary of Wastewater Facility Performance:
The wastewater treatment plant continues to operate extremely efficiently. The facility was in 100%
compliance with their discharge permit during the 2021 year.
During the past year, a new Supervisory Control and Data Acquisition (SCADA) system has been installed at the
treatment plant. This new system alerts the operation staff within seconds of abnormalities at the treatment
process. As a result, they can respond much more quickly to ensure the process continues to operate as
intended.
It is our goal and standard at Carolina Water Service of North Carolina to continually meet 100% of our NPDES
permit discharge limits. We evaluate our treatment processes daily to ensure that goal is obtained. Our permit
requires us to continually monitor the effluent to determine if the treatment processes are working
effectively. This monitoring consists of sampling at various points in throughout the treatment process.These
sample parameters include: Flow measurement of how much wastewater enters and then is discharged from

our plant, Biochemical Oxygen Demand (BOD), Total Suspended Solids, Fecal Coliform,Total Ammonia,Total
Residual Chlorine, Temperature, Total Nitrogen, pH, and Total Phosphorous. A minimum of 705 compliance
samples are taken on an annual basis.
