Innovative Submerged Buoyant Interceptor Sewer System

摘要

"Why build a sewer in a lake? Why make it buoyant? Where has it been done before? Will it work? Will it last? Can we maintain it?" City of Lake Oswego officials and their engineering consultant asked and answered these and many other questions while designing and constructing the innovative pipeline, completed in May 2011 after a 10-year planning, design, and construction process. Total program cost for the six projects is $90 million to replace undersized, deteriorating lines with a system designed to last at least 100 years.
