How does Sauvie Island Moorage compare with other water systems in Multnomah County?
By EPA's size categories, Sauvie Island Moorage is a very small system (500 people or fewer). Multnomah County has 58 active public water systems. Its population served is well below the county average of 14,736 people per system, and accounts for less than 0.1% of the 854,671 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active community water system reports serving 6,703 people, so Sauvie Island Moorage 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. Oregon has 940 active community water systems, 37% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
Who owns and regulates Sauvie Island Moorage?
EPA lists Sauvie Island Moorage as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 27 of the 58 active systems in Multnomah County (47%) are also privately owned.
Does Sauvie Island Moorage have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2025. The violations listed here began between January 2023 and October 2025. By type: 7 public notice, recordkeeping or other, 4 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 5 as resolved, 4 as unaddressed 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. 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.
