South Irvington Sewer Extension

 

Interlaken started work on a public sanitary sewer extension in NE Portland last week. The project consists of installing 239′ of 8″ mainline, 3 manholes, and 2 service laterals. Many of these mainline extensions are an effort to reduce the number of non-conforming sewers in the City of Portland. A non-conforming sewer is commonly referred to as a “Party Sewer”, or more simply when 2 or more houses are connected to one shared sewer lateral that extends to the mainline. This configuration is extremely common in older neighborhoods like Irvington. The primary goal of this work is to create independent connections for all the homes in the City of Portland. Take a look at some of our progress I captured on a site visit last week.
