How does Harbour Isles Master Association compare with other water systems in Manatee County?
By EPA's size categories, Harbour Isles Master Association is a very small system (500 people or fewer). Manatee County has 52 active public water systems. Its population served is well below the county average of 8,369 people per system, and accounts for less than 0.1% of the 435,178 people reported by systems filed under the county. Across Florida, the 5,197 active systems average 4,345 people each. Nationally, the average active community water system reports serving 6,703 people, so Harbour Isles Master Association is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Florida has 1,640 active community water systems, 32% of the state's 5,197 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 85 Florida systems (1.6%) list purchased surface water as their primary source.
Who owns and regulates Harbour Isles Master Association?
EPA lists Harbour Isles Master Association as privately owned. The FL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 43 of the 52 active systems in Manatee County (83%) are also privately owned.
Does Harbour Isles Master Association have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2025. The violations listed here began between January 2018 and November 2025. By type: 6 monitoring and reporting, 4 monitoring and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 10 as resolved, 1 as unaddressed and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
