City updates Fowler Avenue sewer repair: 48-inch casing in place, cost estimate rises to $1.6 million
Summary
Utilities director reported progress on the Fowler Avenue sanitary sewer emergency replacement: pilot bore and materials on site, 48-inch steel casing delivered, dewatering and excavation under way, substantial completion targeted April 15; cost estimate increased from $1.1M to $1.6M and FEMA reimbursement is being explored.
City utilities staff told the council on March 4 that crews have completed the pilot bore and delivered materials for the Fowler Avenue sanitary sewer emergency replacement and that workers are dewatering excavations and preparing to push a 48‑inch steel casing and the new gravity main under Fowler Avenue.
Utilities Director Tinch said contractors have excavated push and receiving pits, the 48‑inch casing and sanitary PVC are on site, and crews are restraining joints on the new gravity pipe so future removal and replacement would be easier. The project’s substantial‑completion date is April 15.
Tinch told council that an early November estimate of $1.1 million was preliminary; a lump‑sum estimate received from the contractor as construction progressed placed the project at about $1.6 million. Staff is pursuing possible FEMA reimbursement because the failure manifested during Hurricane Milton, but he said reimbursement is not guaranteed and the city is prepared to cover the cost from the water and sewer fund if FEMA declines.
Council members asked technical and timing questions. Staff explained “dewatering” in Florida requires well points and pumps to lower groundwater for a 15‑foot excavation and that the new gravity pipe and steel casing are intended to provide long‑term protection (the contractor estimated the replacement pipe life at roughly 50 years). Staff also said they will inspect the remaining parallel gravity line once the new section is in place, and that lining (rather than open‑cut replacement) may be feasible to address other damaged sections.
