Marsh Creek Sewer Line Replacement Project Begins
St. Johns County is launching a proactive infrastructure improvement project in the Marsh Creek neighborhood within the Sawgrass community, aiming to replace a section of aging ductile iron sewer pipe before it causes significant disruption. The Office of Public Affairs produced a video to highlight this project.
The pipe in question runs deep underground and beneath a stormwater pond. While it is still operational, County utility staff identified it as a potential risk and opted to act before any failure occurs.
“If the pipe were to collapse under the pond, we’d face one of two major issues,” said Alan Flood, Senior Engineer for St. Johns County Utilities. “Either the pond could drain into our sewer system—overwhelming it—or sewage could backflow into the neighborhood’s stormwater ponds, which are all interconnected. Neither of those are acceptable outcomes, so we’re taking a preventative approach.”
The County has carefully evaluated how to complete the project with minimal impact to residents. While replacing the pipe does come at a cost, the selected method is far less intrusive than alternatives. The goal is to complete the work in about two months, though the contractor has been given a three-month window to allow for flexibility.
Work is set to begin in late June or early July, with materials already being delivered to the site in preparation.
“This is about being good stewards of our infrastructure and making sure we fix problems before they happen,” Flood said. “By planning ahead, we can avoid emergency repairs and keep our systems running smoothly for the entire community.”
The project reflects the County’s commitment to maintaining essential services while protecting both the environment and the quality of life for residents.
