Costs and Financing Options

The cost of hiring a qualified contractor to replace a non-conforming sewer connection varies with site conditions, but usually ranges from $5,000 to $12,000. Property owners should contact several contractors and request written bids. 

Property owners planning to do the work themselves should contact the Bureau of Development Services at 503-823-7300 for information about plumbing code, inspections and the plumbing permit process. You can also download the Installing Your Private Sewer Line brochure for more information. 

The city offers financing for private plumbing costs and sewer branch charges. Loans have fixed and simple interest rates, low set-up costs and monthly repayment schedules of 5, 10 and sometimes 20 years. There are no prepayment penalties for early payoff. 

The city also offers low-interest loans with deferred payment options to owner-occupants who meet low-income qualifications under the Safety Net Loan Program. For more loan information, call 503-823-4114.
