How does Imperial Plaza compare with other water systems in Worcester County?
By EPA's size categories, Imperial Plaza is a very small system (500 people or fewer). Worcester County has 346 active public water systems. Its population served is well below the county average of 2,239 people per system, and accounts for less than 0.1% of the 774,523 people reported by systems filed under the county. Across Massachusetts, the 1,636 active systems average 6,275 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Imperial Plaza is about half of that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Massachusetts has 246 active non-transient non-community water systems, 15% of the state's 1,636 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.
Who owns and regulates Imperial Plaza?
EPA lists Imperial Plaza as privately owned. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 252 of the 346 active systems in Worcester County (73%) are also privately owned.
