Oregon Revised Statutes Public Health and Safety § 450.295

If any district fails to meet, when due, any obligations sold to the state under authority of ORS 450.250 to 450.300, the State Treasurer and the district may agree upon and put into effect, any plan they may consider expedient for refinancing the indebtedness of the district, or the State Treasurer, with the approval of the circuit court of the county in which the major portion of the assessed valuation of the district is located, may appoint a receiver to operate the sewerage system. The receiver shall act as such so long as the circuit court deems receivership necessary to protect the interests of the state and of the district.
