Projects are under way at the West Point Treatment Plant in Discovery Park that King County says will increase efficiency, improve safety and expand the production and use of renewable energy. The construction activity will be limited to the plant site and should not impact visitor’s use of the park. The plant currently treats about 105 million gallons of wastewater each day.
Here is a list of projects being carried out through 2015:
Waste-to-Energy Project: A new cogeneration system will convert digester gas into a source of heat and electricity for plant operations. When it begins operating in 2012, it will produce about 23,000 Megawatt-hours of electricity each year, equivalent to the electricity needed to power nearly 2,300 homes.
West Point Disinfection Upgrades: The plant’s disinfection system will go from chlorine gas to sodium hypochlorite, which the county says is a safer and more stable liquid similar to strong household bleach. The project is scheduled to be completed by the end of this year.
Screening Improvements: Design will begin soon on a project to upgrade and replace the screening equipment that filters out trash and other debris during the initial phase of the treatment process. The project is scheduled for completion in 2015.
West Point Office Annex: Construction will begin next year on a permanent, modular office annex that will replace temporary construction trailers. The new office space will be available by 2012.
