How does Cottonwood Terrace compare with other water systems in Lincoln County?
By EPA's size categories, Cottonwood Terrace is a very small system (500 people or fewer). Lincoln County has 48 active public water systems. Its population served is well below the county average of 680 people per system, and accounts for 0.7% of the 32,660 people reported by systems filed under the county. Across Nebraska, the 1,226 active systems average 1,472 people each. Nationally, the average active community water system reports serving 6,703 people, so Cottonwood Terrace 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. Nebraska has 599 active community water systems, 49% of the state's 1,226 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 88 Nebraska systems (7.2%) list purchased groundwater as their primary source.
Who owns and regulates Cottonwood Terrace?
EPA lists Cottonwood Terrace as privately owned. The NE state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 29 of the 48 active systems in Lincoln County (60%) are also privately owned.
Does Cottonwood Terrace have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in March 2026. The violations listed here began between April 2016 and March 2026. By type: 7 monitoring and 5 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (7 of them). EPA lists 10 as resolved and 2 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.
