Brightwater Marine Outfall

HWA conducted a geotechnical engineering investigation to support the design and construction of the marine outfall. It extended in excess of 5,000 ft offshore and terminated in a diffuser section approximately 600 ft below sea level. The near shore section of the outfall pipe was placed in a trench, and the offshore portion was placed directly on the sea floor.
