Current Project Report Summary
Throughout August 2026, SGWASA advanced engineering initiatives focused on water treatment, wastewater capacity, and infrastructure reliability. Design of the PFAS Advanced Water Treatment facility progressed toward the 90% milestone, while permitting coordination was completed with the Town of Butner and a final corrosion-control study was delivered. Startup and commissioning of the AquaPRS pilot treatment unit also occurred, beginning a 90-day evaluation of expanded PFAS treatment technology. Construction continued under both packages of the I-85 Sanitary Sewer Improvement Project, including pipeline installation along East Middleton and Joe Peed roads, work at the Joe Peed and East Middleton pump stations, installation near Central Avenue and A Street, preparation for the Norfolk Southern railroad crossing, and directional-bore activities beneath NC Highway 85. Engineering coordination also addressed underground utility conflicts near Eighth and D streets, while restoration activities improved safety and appearance along completed portions of the corridor.
The Creedmoor water meter replacement program reached approximately 77% completion, supporting improved meter accuracy and system modernization. Final draft reports for the water and wastewater infrastructure assessments were reviewed, advancing long-term asset management and infrastructure planning. Completed improvements to all five water treatment plant filters continued to demonstrate longer operating cycles, lower turbidity, reduced chemical use, and improved treatment reliability. Water-quality engineering also progressed through hydraulic modeling, flushing-program development, booster pump station assessments, and distribution-control evaluations. Following increased rainfall and improved Lake Holt levels, the Golden Pond unidirectional flushing pilot was scheduled to begin in September. The Water Treatment Plant Master Plan also remained on schedule, with infrastructure inspections continuing to inform the long-term evaluation of critical treatment assets.
