The Headworks Facility provides preliminary treatment of the influent wastewater. The treatment processes provided by the facility include; influent flow measurement, mechanical fine screening, grit removal, screenings and grit washing, and residuals disposal. Three biofilters provide odor control for the new Headworks Building. The control of the new system is accomplished through the Human Machine Interface (HMI) touch screen and PLC installed in the Control Room of the new facility or via the plant-wide SCADA system.
