NW Thurman Sewer Reconstruction

Updated July 20, 2017

Button. Click to sign up for email updatesEnvironmental Services is designing a project in NW Thurman Street to reconstruct and increase the capacity of the 100-year-old public sewer system that carries both sewage and stormwater in the area. The project will reconstruct 3,100 feet of public sewer pipes and construct new manholes, storm drains, and service laterals that connect private properties to the public sewer. These improvements will accommodate future growth in the area and relieve basement sewer backups at 31 properties.

The project area is bounded by NW Thurman Street to the north, NW Aspen Avenue to the west, NW Savier Street to the south, and NW 30th Avenue to the east. See the project map for proposed pipe work locations.

Schedule

Design is underway. Construction is anticipated to begin in the summer of 2018 and take about a year to complete.

Utility Locates and Soil Sampling

Over the next several months, work crews will occasionally be in the neighborhood to conduct various field investigations to help engineers understand where public utilities are located and what conditions construction crews may encounter below the street surface.

On Tuesday and Wednesday, August 15-16, crews will be drilling holes in street pavement and taking soil samples at several locations along the proposed pipe work illustrated on the map. What the engineers learn from the analysis of soil, rock, and pavement samples will help them determine construction methods.

Before drilling starts, crews will be in the neighborhood to locate and mark underground utilities by painting stripes on streets and sidewalks or placing colored flags in landscaped areas. To learn what each utility locate color means, click here

What to Expect During Soil Sampling

Work crews will collect samples between 7 a.m. and 6 p.m. on August 15 and 16. Work at each site may take a couple hours. Drilling will leave holes a few inches in diameter that work crews will fill immediately after drilling. This work will require temporary lane restrictions and on-street parking closures. There may be brief periods of noise, dust, and mild vibration during drilling.
