How does Old River Water Company compare with other water systems in Churchill County?
By EPA's size categories, Old River Water Company is a very small system (500 people or fewer).

Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active community water system reports serving 6,703 people, so Old River Water Company is well below that figure.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
Who owns and regulates Old River Water Company?

Does Old River Water Company have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2026. The violations listed here began between November 2023 and January 2026. By type: 10 monitoring and reporting and 2 required treatment not met. The contaminant or rule involved most often is Arsenic (7 of them). EPA lists 9 as resolved and 3 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.
