How does Santa Ana Westside compare with other water systems in New Mexico?
By EPA's size categories, Santa Ana Westside is a large system (10,001 to 100,000 people). Across New Mexico, the 1,165 active systems average 1,885 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Santa Ana Westside is about 25 times 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 Mexico has 151 active non-transient non-community water systems, 13% of the state's 1,165 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,009 New Mexico systems (87%) list groundwater as their primary source.
