The site began as a sludge lagoon.
The lagoon was drained in order to begin excavation and backfill to create a site suitable for construction of the proposed upgrades.

The package plant constructed with piping, handrails, and grating.

Activated Sludge Package Plant
The package plant was constructed first due to its elevation. This structure consists of a series of tanks that use biological processes to treat wastewater. Screened wastewater flows into the package plant, and treated effluent from the package plant flows to the disinfection system. The photos below show a progression of the construction.

 

Control Building

The Control Building houses the operator’s office and much of the equipment for facility operations. The Control Building also contains the screening room, where wastewater first enters the facility. A mechanical screen removes debris from the wastewater prior to it entering the package plant.
