Secondary Clarifier
Owner - Facility: Fourth Creek WWTP
Inspection Type: Compliance Evaluation
Yes No NA NE
Comment: All three secondary clarifiers were oDerational and in service. The sludae blanket levels
were measured at approximately nine feet at the time of the inspection. The periodic wet
weather events and water saturated fields caused the facility to maintain a higher than
normal solids inventory due to the inability to distribute and/or land apply bio-solids. The
facility staff were in the process of lowering the solids inventory due to improved weather
conditions and the ability to land apply bio-solids.
