How does Douglas Manor compare with other water systems in Windham County?
By EPA's size categories, Douglas Manor is a very small system (500 people or fewer). Windham County has 254 active public water systems. Its population served is about half of the county average of 251 people per system, and accounts for 0.2% of the 63,868 people reported by systems filed under the county. Across Connecticut, the 2,363 active systems average 1,247 people each. Nationally, the average active community water system reports serving 6,703 people, so Douglas Manor 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. Connecticut has 481 active community water systems, 20% of the state's 2,363 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,263 Connecticut systems (96%) list groundwater as their primary source.
Who owns and regulates Douglas Manor?
EPA lists Douglas Manor as privately owned. The CT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 220 of the 254 active systems in Windham County (87%) are also privately owned.
Does Douglas Manor have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in August 2022. The violations listed here began between July 2000 and August 2022. By type: 5 public notice, recordkeeping or other, 4 contaminant level above the legal limit, 2 reporting and 1 monitoring and reporting. The contaminant or rule involved most often is Public Notice (3 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.
