Sludge Handling & Facility Expansion

In addition to doubling the capacity of the lift station by replacing the existing 7.5HP pumps with 15HP pumps, this project also addressed many deficiencies in the sludge collection, processing, and disposal operations.

First, the existing clarifier mechanism and effluent weir were replaced, and scum collection equipment was added to the existing final clarifier. Additionally, a new sludge processing building was constructed to house a new one-meter belt press and sludge cake conveyer. A sludge cake storage area was also built to allow the City to store the pressed sludge until it could be land applied in the Spring
and Fall.
