How does Jensen Precast compare with other water systems in San Joaquin County?
By EPA's size categories, Jensen Precast is a very small system (500 people or fewer). San Joaquin County has 2 active public water systems, and Jensen Precast is the 2nd-largest of them by population served. Its population served is about 23% below the county average of 33 people per system, and accounts for 38% of the 65 people reported by systems filed under the county. Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Jensen Precast 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. Nevada has 161 active non-transient non-community water systems, 25% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
