Throughout September 2026, SGWASA advanced engineering initiatives focused on water treatment, wastewater capacity, and infrastructure reliability. The PFAS Advanced Water Treatment facility reached the 90% design milestone on September 21, and the updated plans were reviewed on September 30. The National Pollutant Discharge Elimination System permit-renewal application was also submitted, while operation of the AquaPRS pilot treatment unit continued as part of the expanded PFAS evaluation. Construction progressed under both packages of the I-85 Sanitary Sewer Improvement Project. Work included force-main installation along Joe Peed Road, continued construction of the Joe Peed and East Middleton Road pump stations, pipeline installation along Railroad Avenue and A Street, underground boring beneath the Norfolk Southern railroad tracks, and directional-bore activities beneath NC Highway 85. Utility conflicts near Eighth and C streets were resolved, allowing controlled rock excavation to resume ahead of pipeline installation.

The Creedmoor water meter replacement program reached approximately 93% completion, supporting improved meter accuracy and system modernization. Water and wastewater infrastructure assessments were completed, providing updated information for asset management and long-term system planning. Water-quality engineering also progressed through hydraulic modeling, booster pump station assessments, flushing-program development, and distribution-control evaluations. The Golden Pond unidirectional flushing pilot was successfully completed over two days, covering approximately 5.3 miles of water main and establishing a foundation for future flushing programs throughout the service area. Design of the water treatment plant valve replacement project remained complete, while the Water Treatment Plant Master Plan continued advancing critical infrastructure evaluations and long-term treatment planning.
