The Brunswick-Glynn County Joint Water and Sewer Commission is expected to consider a sewer system upgrade on Thursday to make more room for commercial development.

Sewer pump station 4021 — referred to as the Sonic station due to its proximity to a Sonic Drive-In restaurant on Altama Avenue, according to JWSC Engineering Director Todd Kline — is pumping more sewage that it was designed for, Kline said.

Around $275,000 in upgrades to the station and pipes leading to and from it will accommodate the current load plus some.

“(The) upgrades will cover existing demand and what we see in the future,” Kline said.

Several commercial developments have been proposed in the area, he said, and the upgrades will take those into account.

He compared it to another project the commission recently approved at Exit 29 of Interstate 95. There, residential and commercial demand was held back by an over-capacity sewer line and pump station.

Commissioners approved $275,000 in spending on that project in October. Utility staff will ask the commission for around $275,000 to complete the Sonic station project as well, Kline said.

The utility’s five-year improvement plan called for $200,000 in upgrades to the station, but an additional $75,000 is being tacked on to cover planned future development, according to a memo to the commission about the project.

Also on the utility’s agenda is the transfer of water and sewer assets in the Tabby Place subdivision.

At the end of development, developers typically transfer ownership of any water and sewer infrastructure along with easements to the JWSC, Kline said. Once it’s done, the utility will take over repairs and maintenance, he added.

The 24-lot subdivision is located on the corner of North Harrington Road and Harrington Lane on St. Simons Island. Glynn County commissioners approved a final plat for 20 of the proposed 24 lots in the subdivision. Utility commissioners are also expected to discuss its strategic business plan and hazard pay for employees and hear updates on its three wastewater treatment plants and a roundup program.

The meeting is scheduled for 2 p.m. Thursday in the utility’s office, 1703 Gloucester St. in Brunswick.
