West Point TP Waste-to-Energy

PROJECT DESCRIPTION

The King County West Point Treatment Plant Waste-to-Energy Project involved construction of a new cogeneration system at the existing wastewater treatment plant design to convert digester gas, the natural byproduct of the solids treatment process, into a source of heat and electricity for plant operations.  The $15 million dollar project was funded in part by the EPA and now produces both power for the existing water treatment facility and nearly 2,300 homes through the use of a complex power interconnection with the local utility.  An existing treatment plant building was completely retrofitted and upgraded to house the two new 2.3MW power generators, exhaust systems, piping and electrical gear.
