Oregon Revised Statutes Cities § 223.594

(1) When water service is provided to a multifamily building with five or more units with a single water meter, the owner of the real property shall be considered the user of the water. If payment for such water is not made when due and the water service has not been shut off or will not be shut off, the municipal utility may place a lien on the premises to which water service was provided for the amount due for such service.

(2) When requested by the property owner and authorized by the municipal utility, a single water meter may serve several parcels of real property owned by the same owner. The owner of those parcels of real property shall be considered the user of the water. If payment for such water is not made when due and the water has not been shut off or will not be shut off, the municipal utility providing such service may place a lien on the real property to which water service was provided for the amount due for such service.

(3) At any time after 60 days from the time the lien is entered in the lien docket of the local government, in addition to any method provided by law, ordinance or the charter of any local government, the lien may be foreclosed in the manner provided under ORS 223.510 to 223.595.
