<br />2. Primary Clarifier, Hauled Waste, Aerobic Digester, and Dryer Upgrades
<br />Construction of two primary clarifiers, an aerobic digester, digester control building, headworks improvements,
<br />installation and commissioning of an owner-furnished biosolids drying system, and a hauled waste receiving
<br />and pump station at the Three Rivers Regional Wastewater Treatment Plant. Other work includes a flow split-
<br />ter structure and gates, replacement of primary sludge pumps and piping, associated yard piping, electrical
<br />upgrades, instrumentation and controls upgrades, grading and drainage improvements, and paving. The work
<br />includes demolition of two clarifiers, existing headworks channels, primary diversion structure, primary sludge
<br />pumps and piping, grit removal equipment, hauled waste station equipment, and solids handling equipment. The
<br />headworks improvements include installation of a grit chamber and bypass structure. Solids handling improve-
<br />ments will include installation of several sludge pumps, a rotary drum thickener, and a drum dryer system.
