The PUD provides industrial grade (non-potable) water to industrial and irrigation customers.

The two PUD treatment facilities draw water from the Nooksack River. The function of the plants is to provide primary treatment, which lowers turbidity levels before conveying the water to its customers. A minimal amount of chlorinating is done to prevent algae growth in the settling basins.  The water from the two treatment plans serves the Cherry Point Industrial Area, to the northwest of Ferndale – as outlined on the map below in orange below.  The PUD also operates a separate, small potable (drinking) water system and fire water to the Grandview/Interstate-5/Industrial Area, northeast of Ferndale – as outlined on the map below in purple.
