[ARCHIVED] Sanitary sewer overflow stopped; One Tree Hill Way reopened

Work zone traffic sign

Crews have stopped a sanitary sewer overflow (SSO) that had been ongoing since Tuesday at CFPUA’s Pump Station Number 10 (PS 10) near EUE / Screen Gems Studios.

CFPUA staff and contractors’ crews have been working around the clock since Tuesday to limit the amount of untreated wastewater entering the environment and stop the SSO. About 12:55 a.m. Thursday, they completed the installation of approximately 500 feet of temporary pipe to divert the flow of untreated wastewater from a force main that ruptured Tuesday into a new force main.

Thursday morning, One Tree Hill Way was reopened to regular traffic.

The temporary bypass will allow crews to assess damage to the ruptured force main and make repairs.

The force main that ruptured was slated for decommissioning in June 2020 when work is scheduled to be complete on an upgraded replacement for PS 10, which is under construction. The bypass installed to stop the SSO is diverting wastewater into a new 30-inch force main that is part of the replacement PS 10 project.

During the SSO, some portion of the untreated wastewater from the ruptured force main entered Smith Creek from Tuesday until the bypass was installed. The amount of wastewater released as a result of the SSO has not yet been determined.

CFPUA Environmental Management staff continue to conduct water quality testing. Results from Wednesday showed elevated levels of bacteria in Smith Creek adjacent to PS 10 and the bridges over Smith Creek at 23rd Street and Castle Hayne Road, as well as in Burnt Mill Creek at Archie Blue Park. Additional testing is ongoing.

The incident has been reported to the N.C. Division of Water Quality.
