BUTNER — Board members of the South Granville Water & Sewer Authority spent much of Tuesday’s meeting listening to presentations, including the Hazen and Sawyer Water Treatment Plant upgrade.

Lamya King, project engineer, presented the board with revised drawings of the proposed new WTP. King said the project would be ready to put to bid within the next couple of months.

David Bradley from Hazen and Sawyer presented the water capacity study information. Bradley gave a projection of 2.59 million gallons per day of water would need to be produced by 2020 and up to 3.19 million gallons per day in 2050.

Hydrostructures PA gave an update on an asset inventory and assessment project. This focused on updating SGWASA’s geographic information system to include detailed location and attribute data for the Creedmoor sewer collection system and inventory, and inspecting 13 major sewer pump stations.

The work would include inspecting 880 manholes within the Creedmoor sewer system and confirm locations on GIS. The pipes connected to the manholes were inspected by using a zoom camera to look into the pipe for blockages or failures.

Brandon Sykes from Hydrostructures said 13 major lift stations would be inventoried and inspected for site functionality, structural and mechanical inventory, pumping capacity, electrical and control systems and standby power.

Sykes discussed the risks/consequences of failure analysis and prepared a 10-year cost improvement plan for repair/replacement/rehabilitation of the sewer system of SGWASA.

Jim Thames, with Coulter Jewell and Thames, presented the board with a Sanitary Sewer Study Master Plan. Preston Royster reviewed the long-term needs that 16 pump stations need to be removed, with six existing stations to remain with upgrades. Royster recommended nine new lift stations.

Chuck Hill from Coulter, Jewell and Thames evaluated 13,340 acres of undeveloped areas in southern Granville County for potential future development. Hill said SGWASA could have the capacity to serve 14,000 new homes in the future if this land is developed.

Thames added the projected cost of the master plan would be upwards of $47,707,000.

The next regular SGWASA meeting is scheduled for Aug. 13 at 6 p.m. in the Butner Council Chambers, 415 Central Ave.
