How does Sterling Plaza compare with other water systems in Sussex County?
By EPA's size categories, Sterling Plaza is a very small system (500 people or fewer). Sussex County has 476 active public water systems. Its population served is about 45% below the county average of 425 people per system, and accounts for 0.1% of the 202,506 people reported by systems filed under the county. Across New Jersey, the 3,496 active systems average 2,750 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Sterling 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. New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.
Who owns and regulates Sterling Plaza?
