Classification of Drinking Water
Subsystems and Wastewater Facilities

Most drinking water and wastewater systems are required to be classified. Classification is a means to determine the relative operational complexity of a system. The relative complexity will then help determine the certification requirements for individuals operating those systems.

The following forms are used to classify a new drinking water subsystem, wastewater facility or to re-classify an existing subsystem/facility that has undergone infrastructure changes and thus warrants review and re-classification. Municipal residential subsystems/facilities may be classified from Class 1 to 4 depending on the complexity of the subsystem/facility.
