Wastewater System Overview
Cape Fear Public Utility Authority (CFPUA) is the primary wastewater
services provider for New Hanover County and the City of Wilmington,
serving more than 75,000 individual homes, businesses, and other
properties. CFPUA operates and maintains two wastewater treatment
plants (WWTP), 158 pump stations, and over 1,100 miles of sewer mains.
In Fiscal Year 2024, which spanned from July 2023 to June 2024, CFPUA
collected and treated approximately 6.4 billion gallons of wastewater.
CFPUA spent $14.94 million to operate and maintain the wastewater
system and invested another $38.9 million in system growth and capital
upgrades, repairs, and replacements of aging infrastructure.

Biosolids Management
Beginning in 2019, CFPUA transitioned to an in-house managed wastewater residuals
program. CFPUA's managed residuals program consists of dewatering, contracted
hauling of dewatered residuals, and landfill disposals. Landfill disposal is expected to
continue due to the presence of PFAS in the dewatered residuals. Below is the fiscal
year 2024 (July 2023—June 2024) program report for Southside WWTPs, Northside
WWTP, and the alum sludge processed for Sweeney Water Treatment Plant:

CFPUA has a continual commitment to Being a utility in a coastal community,
undergo projects that assist in lowering CFPUA has to implement and modify
strain on the collection system and treat- pump stafions to remain resilient against
ment plants, which includes tackling inflow /1
climate-related threats such as flooding
& infiltration (I&I) challenges. Resiliency from storm related events and rising sea
measures taken to reduce l&I includes levels. Between July 2023 and June 2024,
lining of CFPUA sewer gravity mains. The CFPUA has modified 5 pump stations by
lining process prevents surface water from = installing permanent generators, flood-
entering into pipes and manholes by in- resistance structures, and upgrading
stalling a protective lining that ensures no aging infrastructure. CFPUA is continually
additional inflow, but also extends the in the process of proactively installing
lifespan on the pipes. So far, CFPUA has resilient and reliable infrastructure and

Southside Wastewater Treatment Plant Replacement
i
CFPUA is preparing to launch the biggest capital project in the organization's history: replace-
ment and expansion of the Southside Wastewater Treatment Plant. Replacing the Southside
Plant is necessary to continue meeting our community's wastewater treatment needs,
accommodate future growth, and protect our local environment.
At 52 years old, much of the Southside Plant's infrastructure is nearing the end of its useful
life. The project will replace the existing facility with new infrastructure and more modern
treatment technology. The project also will expand Southside's treatment capacity from 12
MGD to 16 MGD. This capacity increase is needed to meet future demand as CFPUA's
customer base continues to grow.
