| Abstract | Long Description |
A limited Class II inspection and receiving water survey were conducted by the Department of Ecology at Wilkeson Wastewater Treatment Plant on March 3 and 4, 1987. Severe infiltration and inflow caused hydraulic overload of treatment processes. Facility retention time was 2.5 days, less than the recommended three-day minimum for an aerated lagoon system. During the inspection, the plant was not in compliance with NPDES permit limits for biochemical oxygen demand (removal efficiency and loads), fecal coliform numbers, or flow. However, effects of wastewater discharge on Wilkeson creek were minimal due to high-stream flows and associated poor water quality. A number of recommendations were made to improve plant performance, foremost of which was correction of the infiltration and inflow problem. |
