From then to now: Since 1974, when open sludge lagoons were present on the South Beach at Discovery Park, West Point Treatment Plant has been upgraded to provide award winning wastewater treatment service to our growing region, protecting Puget Sound water quality. Covering treatment processes, installing odor scrubbing equipment, and modifying maintenance practices helps to control odor. Landscaping improvements have restored shoreline areas to a natural area with public access.
