Investing and innovating at the forefront of science and technology to capture the benefits and make early gains

First-of-its-Kind In-Lake Buoyant Pipeline
Brown and Caldwell's creative engineering design replaced an aging 2–mile underwater interceptor in Lake Oswego, Ore., with an unprecedented buoyant, flexible gravity sewer constructed of HDPE pipe. The $100 million project – that also includes 1.5 miles of pile supported pipe, 3 miles of cured–in–place rehabilitated pipe and two new pumping stations – allows the city to replace an undersized, corroding, earthquake-vulnerable system with a seismically sound, lower–cost, low–impact system designed to meet the city's needs for another 100 years.
