How does Grand Harbor WSC compare with other water systems in Wise County?

By EPA's size categories, Grand Harbor WSC is a very small system (500 people or fewer). Wise County has 60 active public water systems. Its population served is about half of the county average of 734 people per system, and accounts for 0.8% of the 44,014 people reported by systems filed under the county. Across Texas, the 7,078 active systems average 4,789 people each. Nationally, the average active community water system reports serving 6,703 people, so Grand Harbor WSC 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. Texas has 4,594 active community water systems, 65% of the state's 7,078 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 1,192 Texas systems (17%) list purchased surface water as their primary source.

Who owns and regulates Grand Harbor WSC?

EPA lists Grand Harbor WSC as privately owned. The TX 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 60 active systems in Wise County (72%) are also privately owned.

Does Grand Harbor WSC have drinking water violations?

Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in April 2026. The violations listed here began between September 2025 and April 2026. By type: 6 contaminant level above the legal limit, 4 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminant or rule involved most often is Public Notice (4 of them). EPA lists 5 as unaddressed, 5 as archived and 2 as resolved. 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. 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.
