SGWASA Engineering Project
I-85 Sanitary Sewer Improvement Project
CP1 - Increase wastewater system capacity through new pump stations and pipeline installation supporting long-term service reliability.
CP2 - Deliver the Southern Interceptor sewer construction package while managing funding and sequencing constraints.
Budget:
CP1 - $34M CP2 - $30.24M (NTE award)
Current Milestone:
SGWASA, USDA, and NCDEQ
I-85 Sewer Upgrade CP#1 and CP#2 in progress with Southern Interceptor proceeding; Northern Interceptor deferred pending further funding discussion.
Construction of CP#1 continues on schedule and within budget.
CP#2 construction also remains active on the Southern Interceptor; however, the Northern Interceptor portion has been deferred pending a Board review of the projected $8 million cost and funding options.
Funding:
CDM Smith, Haren Construction, Park Construction of NC, NC Department of Environmental Quality, United States Department of Agriculture, Town of Stem, Town of Butner, City of Creedmoor, Granville County
SGWASA serves southern Granville County, including Creedmoor, Butner, and Stem. Due to maxed-out wastewater system capacity, a development moratorium was enacted in 2018 for parts of Creedmoor and Butner. From 2019–2025, SGWASA collaborated with partners to design and fund a solution. CDM-Smith completed engineering plans and split the project into two construction packages: CP#1: Bid in July 2024; contract awarded to Haren Construction for $34.8M in December 2024. CP#2: Bid in May–June 2025. Total estimated project cost: $75 million.
CP#1 Status: CP#1 includes the construction of two new sewer pump stations and the installation of new sewer pipe (gravity and force main). Haren Construction started construction on 4/1/25.
CP#2 Status: A recommendation of contract award to Park Construction for the Southern Interceptor Sewer construction occurred at the October 14, 2025, Board of Directors meeting. The Board of Directors approved a contract with Park Construction NC, Inc., in the not-to exceed amount of $30,238,282. The project is funded in part by the United States of Agriculture (USDA). Construction for CP#2 started in November 2025.
