Water and Wastewater Facility Classification
The Drinking Water and Wastewater Facility Operating Regulations, which came into effect January 1, 2005, require that owners of water and wastewater facilities register their systems with the department. As of April 1, 2005, all municipal systems are required to have certified operators, and as of January 1, 2006, all systems serving the public are required to be registered. Also, as of January 1, 2006 systems serving five or more households are required to have certified operators in charge of their systems.
Water Distribution (WD) and Wastewater Collection Systems (WWC) are classified according to the population that each system services, whereas Water Treatment (WT) and Wastewater Treatment (WWT) Systems are classified according to the size and the complexity of the components of the systems. This classification determines the Operator Certification and monitoring requirements for the system(s). The following table outlines the categories and level of systems:
