James Island council approves slip-lining repairs for failing corrugated pipes; vac-truck purchase and drainage projects discussed

Summary
The Town Council approved slip-lining repairs for failing corrugated pipes in Quail Run and Peregrine subdivisions and heard updates on a vac-truck pilot and multiple stormwater projects; officials said slip-lining is less disruptive and cheaper than full replacement.
The Town Council of James Island voted unanimously to award slip-lining repairs (a trenchless pipe rehabilitation method) for failing corrugated stormwater pipes in the Quail Run and Peregrine subdivisions.
Council members and staff said the slip-lining method — offered by PDC Pipeline and Drainage in the council packet — avoids digging up roadways, lowers cost compared with full replacement, and can extend pipe life by decades. The motions to award the work carried unanimously.
Why it matters: Several neighborhoods on the island have aging corrugated pipes under their streets that are failing and causing sinkholes and localized flooding. Town staff said the slip-lining approach reduces disruption to residents, lowers contractor mobilization costs when several repairs can be scheduled together and may save taxpayer dollars versus full excavation replacements.
Public works updates: Keith Ledoux, public works director, told the council the Woodhaven and Ocean View stormwater projects are now closed out following inspections and additional contractor work. He said crews are preparing two pipe lining or replacement operations in the Quail Run neighborhood and that other approved maintenance projects are awaiting contractor start dates.
Vac truck discussion: Council members reviewed estimates for a new vacuum (vac) truck and a demonstration unit. Staff said the truck can squeeze water from dredged culvert material, allowing crews to do more clearing before returning to dump sites. The vac-truck purchase was discussed but not approved at the meeting; council members said staff will arrange demonstrations for the public and council to evaluate equipment.
Council action: Two separate motions to hire PDC Pipeline for slip-lining repairs in Quail Run and Peregrine were approved unanimously. Council members emphasized that the county does not perform slip-lining and that county replacement estimates were higher because full excavation would be required under county scope.
Next steps: Staff will schedule the vac-truck demonstrations and return with cost comparisons and operational plans. Town staff also said they will organize a sandbagging event and that the Green Hill repaving will be scheduled for the summer after school ends.
