Attention, open in a new window. Print

This project began in November 2009 on two sites.  E.E. Austin's work includes all of the concrete structures, new masonry buildings, new wood pole barns, as well as all treatment equipment and piping.

Site I work includes several buildings, including a garage, two pump and blower buildings, an aeration tank, a 78' x 78' aerobic digester, and headworks building.

Site II includes an 86' diameter treatment tank, reactor clarifier, headworks building, two blower buildings, sludge building, and several other structures.  The project adds a third treatment "train" to the plant.  The train is now operational and the two existing trains are being renovated.

Renovations to the existing pump house on the Erie Bayfront, with the addition of storage, and a visitor's area.  Our work involved demolition of part of the existing pump station and addition of a new masonry building. The new building re-used the stone archways from the old structure. Work also included new tile roof, new windows, and landscaping.

Johnson Reservoir Geodesic Dome

This interesting project was done at the Johnson Reservoir in Erie.  It involved removing the existing concrete roof structure and replacing it with a new 170' diameter aluminum geodesic dome.

After cutting up and removing the concrete lid, we drained the reservoir.  Then the dome was assembled and hoisted up to be set on the reservoir wall.

Erie Wastewater Treatment Plant

Attention, open in a new window. Print

We have done dozens of projects at the Erie Wastewater Treatment Plant through the years, including work on the new Overflow Retention Facility where we modified an existing sludge holding tank into a chlorination tank.The scope of work included 30' high concrete baffle walls, 60" diameter piping, and slide gates.  We built concrete duct banks and equipment foundations for an electrical systems upgrade and concrete foundations, paving, and polymer feed system for an equipment building.  We installed a new 12' diameter, 18' deep storm water concrete lift station, complete with valve vault, piping, pumps, and removal of the existing lift station.  We built a new 27,000sf sludge thickener building that included site shoring, massive excavation, slurry walls, dewatering, concrete structure, as well as process equipment, pumps, process piping, and electrical controls.
