Environmental Services (BES) has successfully completed sewer construction on the Slabtown Sewer Replacement Project located in NW Portland (between NW Thurman and Overton and 12th to 21st). The project repaired or replaced 8,400 feet of sewer mains in streets, some of which were more than 115 years old and deteriorating due to age. Taking these actions now will help protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets.

A Note of Appreciation

The Slabtown Sewer Repair Project was a major construction project that spanned nearly six years of design and construction. Environmental Services knows it has meant significant inconveniences for businesses and the many people living, working, and visiting in the project area. We appreciate your cooperation and patience as we worked through the unique technical challenges of the neighborhood (both above and below ground) to complete the necessary public sewer repairs. Thank you. 

Environmental Services expresses special appreciation to the dozens of property owners, property managers, facility managers, and business owners and operators who collaborated with us to help us complete the sewer repair work. Thank you.

We want to hear from you

We would like to know about the access needs at homes and businesses in the area, as well as any parking concerns, delivery schedules or other information you would like to share. Please contact us directly (information below).
