County Data Read · Trailing 12 Months

What the Data Shows in Collier County

Across the trailing 12 months, Collier County logged 16 sanitary sewer releases in FDEP public notices, with 567,490 gallons reported in total. Collier County lands at number 8 of 40 counties for reported volume. The single largest event in the window released 330,000 gallons. The most recent notice is dated October 10, 2026. A count of 16 puts Collier County where targeted CCTV pipeline inspection pays off early. Collier County is predominantly newer construction, with US Census ACS housing age estimates placing only 16.8% of 234,732 housing units before 1980. Median structure age across Collier County runs about 31 years. Newer stock lowers material risk in Collier County, though joints, laterals, and manholes still take on infiltration and inflow.

Collier County took only 33.6 inches over the trailing 12 months in NOAA precipitation data (100% coverage). A dry window understates risk, because Collier County never saw the groundwater that exposes infiltration and inflow. With 1 enforcement action and 1 active consent decree logged in EPA ECHO, Collier County utilities are working against defined milestones rather than discretionary ones. Because Collier County lies in Southwest Florida, the fair comparison set is Charlotte and Lee counties. Southeast Services covers Collier County with statewide capability, mobilizing crews to the county for CCTV pipeline inspection and cured-in-place pipe (CIPP) lining.
