Description A Class II Inspection was conducted at the Alderwood Water District's Wastewater Treatment Plant in October 1992. Level of treatment and wastewater flow rates were acceptable during the inspection. The plant's discharge was well within the NPDES permit effluent limits. However, influent BOD5 loading exceeded the plant's design capacity and influent TSS was at the design capacity. Planned hookups within the Alderwood Water District service area to the Metro North Creek trunk line, will reduce influent loadings to the treatment plant. Bioassays indicated only limited toxicity of the chlorinated effluent to some test organisms. Sediment bioassays demonstrated no toxic effects.
