How does Granite Construction compare with other water systems in Washoe County?
By EPA's size categories, Granite Construction is a very small system (500 people or fewer). Washoe County has 64 active public water systems. Its population served is well below the county average of 7,708 people per system, and accounts for less than 0.1% of the 493,331 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 Granite Construction 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.
Who owns and regulates Granite Construction?
EPA lists Granite Construction as privately owned. The NV state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 43 of the 64 active systems in Washoe County (67%) are also privately owned.
