The City of Stayton provides wastewater treatment for 10,000 people in the local community as well as the nearby City of Sublimity. The facility was originally built in 1962 and, despite upgrades over the years, had become increasingly challenged to meet the more rigorous standards for surface water discharged into one of the state’s high-priority watersheds.
In 2010, USDA Rural Development approved an $8.3 million loan and $2 million grant to overhaul the system. The improvements and new installations, which were completed in 2012, not only improve the level of treatment, but also increase capacity for an estimated 3.35 percent annual rate of growth over the coming years.
Among the upgrades are new sludge handling facilities, a new plant utility water system, selector cell, high-efficiency turbo blowers, maintenance building, mixing pumps, storage tank, and other various upgrades. Also, walkways were added to an existing storage tank to improve access and safety for employees. The project also added upgraded filter buildings and Ultraviolet (UV) components, which provide an additional, advanced level of disinfection for treated water exiting the system.
In addition, the public works department was able to install a new sludge dryer, which uses heat to eliminate vectors and pathogens from the leftover biosolids. The new equipment processes the material to a standard that is rated as exceptional quality (Class A) and approved for use as safe fertilizer for a wide range of agricultural crops. Because of the quality of the processed biosolids, farmers are eager to take it, and the city will no longer have to pay for handling and disposal.
The modernized wastewater facility will ensure proper treatment and protect water quality for the community now and as it works to expand the local economy over the coming years.
