Wash. Rev. Code § 90.03.560
When requested by a municipal water supplier or when processing a change or amendment to the right, the department shall amend the water right documents and related records to ensure that water rights that are for municipal water supply purposes, as defined in RCW 90.03.015, are correctly identified as being for municipal water supply purposes. This section authorizes a water right or portion of a water right held or acquired by a municipal water supplier that is for municipal water supply purposes as defined in RCW 90.03.015 to be identified as being a water right for municipal water supply purposes. However, it does not authorize any other water right or other portion of a right held or acquired by a municipal water supplier to be so identified without the approval of a change or transfer of the right or portion of the right for such a purpose.
