Downtown-Old Town Sewer Repairs

Updated March 15, 2018

Environmental Services has begun a major sewer repair project in downtown Portland to repair public sewer pipes that are between 100-140 years old and in deteriorating condition. The SW Yamhill-Morrison Sewer Repair Project will be in construction from March 15 to May 20, with the most challenging work to be done in May.

Businesses in the survey area highlighted on the map below are encouraged to complete the Downtown Business Sewer Questionnaire to help the city and its contractors prepare for the most challenging pipe repair work in May.

Map of survey area

If you own, operate or manage a business or building within the survey area shown on the map above, please click here to complete a Business Sewer Questionnaire. If your business or building is outside the survey area shown on the map above, please do not complete the questionnaire at this time.

The information you provide will help engineers understand your sewer connection and business operations better so we can:

  • Maintain your sewer service during repairs
  • Appropriately connect you after repairs are completed
  • Minimize disruptions to your business as much as possible.

Any repairs the city makes to the public sewer pipes downtown will have long-term benefits for your business for many years to come and will help prevent sewage releases to downtown businesses and streets.

Thank you for completing the Business Sewer Questionnaire.

Throughout 2017 and into 2018, the Central Business District will be the site of multiple projects to repair and replace aging sewers, rail lines, bridge structures, streets, and other infrastructure. Projects with long-term benefits will cause short-term disruptions to residents, businesses and visitors. Environmental Services is coordinating with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. For more information, visit
