SGWASA Engineering Project
WTP Water Valve Replacement
Complete valve replacement work at the WTP, timed to avoid conflicts with filter media replacement.
Budget:
$155,980.00 Design
Current Milestone:
The project design is 98% completed.
Design will continue once the project resume, with guidance from the South Granville Water & Sewer Authority Board.
Funding:
Hazen & Sawyer
Following a main break at the Butner WTP, SGWASA has experienced recurring leaks and valve failures along the water main between the clear well and finished water pumps. These issues have caused erosion and highlighted the lack of bypass options and redundancy in the system.
For this project, Hazen and Sawyer is evaluating valve repair alternatives, followed by final design, permitting, and bidding for the selected solution. Construction-related services may be added later via amendment. The total cost for the project evaluation and design is $155,980.00. The probable cost of construction will be developed when final repair alternatives are selected.
In November, Hazen and SGWASA staff met at the WTP to review some additional pipe replacement work to ensure a successful valve installation. The outcome of this review caused some additional engineering design work to be performed.
Due to the cost of the project, the project will be considered for public bidding and construction in 2026.
