-7 Main Leaks Occurred between 4/22/25 & 6/18/25
-Records show 9 Total Leaks b/t Harbor Walk & Breakwater
-Each leak requires full closure of Lemay Ave for 18 – 24 Hours
-Repair costs estimated between $140,000 - $175,000
-Leak repair doesn't affect individual services but creates isolated
system vulnerability

- Existing main is 1979 Ductile Iron Pipe direct buried w/out plastic wrap
-All 9 Failures have been electrolysis holes on top of pipe
-1979 vintage pipe exists from Harbor Walk to Harmony Road (~2,800 L.F.)
-1985 vintage pipe N. of Harbor Walk (plastic wrap & no known leaks)
-Recommend replacing the entire 2,800 L.F. of existing Ductile Iron Pipe with
new Polyvinyl Chloride Pipe (PVC).
-Design will determine the exact sizing and location within Lemay Ave which
can hopefully lower cost estimates.
-Construction to be completed by summer of 2026 to meet water demands
