Snake in a Lake—An Innovative Pipeline Design
This article discusses the Lake Oswego Interceptor Sewer (LOIS) project, a first‐of‐its‐kind pipeline project that will protect the water quality of Oregon's Oswego Lake through seasonal changes in water temperature and in the event of an earthquake. The project was undertaken to replace a 50‐year‐old corroded, undersized, and seismically vulnerable concrete cylinder sewer pipe under the lake with a larger, flexible, high‐density polyethylene (HDPE) pipeline. LOIS is the first known buoyant gravity sewer in the world. LOIS' submerged, buoyant stainless‐steel access points provide entry points to the pipeline without affecting boat navigation, and the installation of removable access caissons allows cleaning and inspection equipment to be inserted into for infrequently required maintenance. Specific challenges unique to the project are discussed.
