Who needs a CCN?
Investor-owned utilities (IOUs), Water Supply Corporations (WSCs), and affected counties are required to have a CCN.
While some municipalities and districts choose to obtain a CCN, they are not required to have one unless the district or municipality seeks to provide retail water or sewer service within an existing CCN.
An exempt utility is a water utility that provides retail water to less than 15 potential connections for compensation and that is not located in another utility’s CCN service area. Exempt utilities may register with the PUC as an “Exempt Utility”.
