Interlaken recently completed another sanitary sewer mainline extension for the City of Portland Bureau of Environmental Services. The project encompassed installation of over 250′ of 8″ PVC pipe, 4 sanitary service laterals, and one sanitary manhole.


We also are utilizing our Operators Apprentice from the Northwest College of Construction. Below is a photo of him performing trench backfill. To learn more about the NWCC Apprenticeship Program click here.

I must say, it was a beautiful day for a site visit!
