How does Greenwich Water Works Co compare with other water systems in Piute County?
By EPA's size categories, Greenwich Water Works Co is a very small system (500 people or fewer). Piute County has 11 active public water systems, and Greenwich Water Works Co is the 6th-largest of them by population served. Its population served is about half of the county average of 154 people per system, and accounts for 4.4% of the 1,688 people reported by systems filed under the county. Across Utah, the 1,133 active systems average 3,458 people each. Nationally, the average active community water system reports serving 6,703 people, so Greenwich Water Works Co is well below that figure.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 898 Utah systems (79%) list groundwater as their primary source.
Who owns and regulates Greenwich Water Works Co?

Does Greenwich Water Works Co have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2024. The violations listed here began between January 2020 and October 2024. By type: 8 monitoring and reporting, 2 public notice, recordkeeping or other and 2 monitoring. The contaminant or rule involved most often is Consumer Confidence Rule (2 of them). EPA lists 11 as resolved 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. 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.
