Salmon Springs supplies 60%+ of the water for the city's water system. This transmission main is the oldest and important infrastructure in the City of Puyallup's water system. Due to the age and critical nature of this transmission main, the City is proposing to construct a new transmission main. This will be accomplished by tying into the 16-inch ductile pipe that was replaced in 1997 south of the concrete dam and following a new alignment down to the existing chlorination compound. The existing portion of transmission main that will be bypassed will remain in place to maintain service during construction, to provide redundancy in case of a landslide or seismic event, and to minimize ground disturbance and vegetation removal in sensitive areas.
