Port Washington

Geosyntec has provided consulting services to We Energies on several sediment removal projects at their Port Washington Generating Station (PWGS), a 545-MW power generating facility on the shore of Lake Michigan. Sediment removal was critical to plant reconstruction activities and continued operations. For an intake and discharge tunnel sediment removal project, the selected removal method was to isolate tunnel segments, dewater and solidify the sediment in-place, and dispose of the sediment in an off-site landfill. For an emergency intake tunnel sediment removal project, the selected removal method was to remove sediment from the tunnel, mix it with a polymeric additive within geotubes to facilitate the dewatering and solidification process, and dispose of it in an off-site landfill.
