What the Data Shows in Collier County

Across the trailing 12 months, Collier County logged 13 sanitary sewer releases in FDEP public notices, with 200,590 gallons reported in total. Collier County lands at number 15 of 38 counties for reported volume. The single largest event in the window released 130,000 gallons. The most recent notice is dated August 21, 2026. A count of 13 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 32.6 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. No active Clean Water Act enforcement is on record for Collier County in EPA ECHO, so budget cycles set the schedule. 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.
