This highly phased project included construction of complete new Headworks facilities within the footprint of the existing Headworks facility. Requirements to maintain plant operations included splitting influent flows between existing and portions of new Headworks systems, construction of temporary channels multiple overnight shutdowns of nearly 30 seperate pump stations feeding the facility to allow for switchovers.
Construction included new influent junction structure with coarse screening, fine screening, grit removal, blower building, pre-aeration basins, odor control, peak flow storage, extensive underground piping and demolition of existing facilities. Peak flow basins converted existing sludge lagoons to concrete lined basins to store up to 30 million gallons of wastewater during rain events. Underground piping included miles of piping from fractional sized water lines to 72″ PCCP peak flow basin lines.
