Community Development Block Grant Infrastructure (CDBG-I) Sewer Line Rehabilitation Project
Funding Agency: Division of Water Infrastructure
Budget: $1,999,129
Estimated Completion Date: August 2024
The City of Dunn sewer collection system consists of over 75 miles of sewer lines ranging in size from 8-inches to 30-inches. Many sewer lines throughout the City were originally constructed during the period of 1920-1960 and were made of short, four-foot sections of vitrified clay (VC) pipe. The joints were constructed of cement mortar and have deteriorated with time. The manholes that have been inspected through various system evaluations which show evidence of infiltration of groundwater through deteriorated joints and cracks. As a result of the deteriorated infrastructure, inflow and infiltration (I&I) or unwanted groundwater and/or rainwater makes its way into the collection system and eventually ends up at the wastewater treatment plant.
The City’s wastewater system is subject to rainfall induced inflow and infiltration (I&I) and has experienced several Sanitary Sewer Overflows (SSOs) on the interceptor line upstream of the WWTP and at Eastside Pump Station. As a result of these overflows and the inability to treat the peak wastewater coming into the plant, the City of Dunn is currently under a system wide moratorium preventing new connections to the sewer system. Improving the wastewater collection system and reducing the I&I flows will therefore reduce the number and volume of SSO’s.
After completing the project, the wastewater system will become more efficient by reducing the flows through the pumping stations and the treatment plant. By reducing the flows through the facilities, the pumps will not run as often, therefore will decrease the amount of energy being used to operate the system. The treatment plant will also save on chemical costs associated with treating I&I diluted wastewater flow.
This rehabilitation project will replace or rehab approximately 13,625 linear feet of sewer line, 56 manholes, and services.
