Nationally, the average active non-transient non-community water system reports serving 430 people, so Dean Warehouse Services is well below 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. Rhode Island has 81 active non-transient non-community water systems, 17% of the state's 465 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 428 Rhode Island systems (92%) list groundwater as their primary source.
