Urban Construction Scene

SGWASA’s SDF policy supports capacity-related utility improvements needed to serve new development now and in the future. SDFs are calculated per Service Unit.

View the link below to learn how SDFs are determined and how funding is allocated to support water and sewer infrastructure.

SGWASA is advancing targeted infrastructure upgrades across the system to strengthen service, support growth, and provide quality drinking water.

On Schedule

Unidirectional Flushing

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.

On Schedule

Brame's Crossing Extension Project

Brame's Crossing

N/A
Budget:

SGWASA is advancing the Brame’s Crossing Phase II water and sewer extensions to support planned development in Creedmoor by extending public utility infrastructure.

On Schedule

SGWASA Water Treatment Master Plan

Water Treatment Master Plan

$150K grant + $30K match
Budget:

Conduct an Asset Inventory and Assessment study of the WTP (Water Plant Master Plan) to support asset management and capital planning.

On Schedule

SGWASA Water Quality Improvements

Water Quality Improvements

$227,340
Budget:

Improve distribution system water quality management through hydrant flushing planning, booster station assessment, hydraulic modeling, and system control evaluations.

On Schedule

SGWASA PFAS Mitigation Program

PFAS Mitigation

$25M - $30M
Budget:

Advance pilot testing and engineering design for a long-term PFAS treatment solution to meet future regulatory requirements.

Current Project Report Summary
SGWASA’s March 2026 engineering report shows continued progress on several major infrastructure projects that support long-term water and wastewater reliability. PFAS mitigation remains on schedule, with engineering design underway, Phase 2 pilot testing advancing, and more than $10.6 million in state-approved funding identified for the treatment effort. The I-85 Sewer Improvement Program also remains active, with CP#1 moving forward and CP#2 continuing on the Southern Interceptor. At the water treatment plant, filter media replacement is progressing toward spring 2026 completion, with the first three filters back in service and the remaining work scheduled through April and early May. In Creedmoor, SGWASA’s water meter replacement program is also moving forward on schedule toward its July 1, 2026 completion target.

Additional system improvement work is also underway across the utility. SGWASA remains compliant with Lead and Copper Rule requirements, with annual notices completed and service-line identification efforts continuing through a pilot program. Water and wastewater infrastructure assessment projects funded through AIA grants remain on track for final reports by May 1, 2026, while broader water quality improvement work continues through modeling, booster station assessment, and control system evaluation. The water valve replacement project has completed design and is expected to move to public bidding, and the water treatment master plan grant project is now underway as SGWASA continues planning for future plant needs.
