Unidirectional Flushing (UDF) Program
$45,000
Budget:
This program is intended to support a more structured and proactive approach to system flushing. The work will help SGWASA evaluate operational methods for improving water quality maintenance, managing sediment and residual conditions, and strengthening long-term distribution system practices.
Routine valve and fire hydrant maintenance was completed in June. Water main flushing was postponed due to high temperatures and localized drought conditions.
Current Project Report Summary
Throughout June 2026, SGWASA advanced engineering initiatives focused on water treatment, system reliability, and wastewater capacity. The PFAS Advanced Water Treatment project reached the 60% design milestone, while planning progressed for permitting, corrosion control, and expanded pilot testing. Construction also moved forward under both packages of the I-85 Sanitary Sewer Improvement Project, including new pump stations, sewer pipelines, and preparations for major roadway and railroad crossings. The Creedmoor water meter replacement program reached 55% completion, and rehabilitation of all five water treatment plant filters was completed, resulting in longer operating cycles, lower turbidity, reduced chemical use, and improved treatment reliability.
Water and wastewater infrastructure assessments reached substantial completion, supporting updated asset inventories, hydraulic modeling, condition assessments, and long-term infrastructure planning. Engineering design for the water treatment plant valve replacement project was completed, while broader water-quality evaluations continued through hydraulic modeling, booster pump station assessments, flushing-program development, and distribution-control reviews. Valve and hydrant exercising was completed within the Golden Pond pilot area, although flushing was postponed due to hot weather, localized drought conditions, and Lake Holt water levels. Specialized divers also completed internal and external inspections of the raw-water intake structure as part of the Water Treatment Plant Master Plan.
