Water System Type
From the help published with Drinking Water Watch 3.5, reproduced as delivered.
Water systems are classified according to rules developed
by the U.S. Environmental Protection Agency (EPA) and each state. Water
Systems fall into two broad categories: public and non-public. A public
water system can be further classified as one of the following:
This classification is based on information in each of the following five areas:
| C - Community | Serves at least 15 service connections used by year-round residents or regularly serves 25 year-round residents. |
|---|---|
| NTNC - Non-Transient Non-Community | Serves at least the same 25 non-residential individuals during 6 months of the year. |
| NC - Transient Non-Community | Regularly serves at least 25 non-residential individuals (transient) during 60 or more days per year. |
This classification is based on information in each of the following five areas:
|
|
Quantity and type of population served (e.g., transient, residential). |
|---|---|
|
|
Number of days served (or annual operating period (i.e., the period(s) of the year that the water system is in operation)). |
|
|
Number of service connections (i.e., the number of connections for each service area such as commercial, agricultural, residential). |
|
|
Activity status of the water system (i.e., active or inactive). |
|
|
Sources of water (e.g., reservoir, well. Sources of water may be active or inactive depending on whether the source is seasonal or year-round. The current date determines active or inactive status). |
