The Wastewater Treatment Plant is located at 1202 N. "M" Road and operates 24 hours per day, 7 days a week, and 365 days a year for the proper treatment of raw sewage waste.  The City owns and operates its own wastewater system.  The wastewater treatment plant is a combination of the conventional type and an oxidation ditch type with a total treatment capacity of 5.3 MGD with a permit capacity of 5.9 MGD.  The aeration tank treatment plant has a capacity of 1.9 MGD, and the oxidation ditch plant has a capacity of 1.4 MGD.  In July 1998, the City completed the construction of an expansion to its existing wastewater treatment plant, which consisted of an orbal biological treatment system with a capacity of 2.0 MGD aeration.  The City is currently in the design phase for the construction of an additional treatment capacity of 2.0 MGD.  The scope of work planned for the expansion includes the headworks with screening and de-gritting units, the addition of the 3rd outer ring to the Orbal unit, the addition of another clarifier to the Orbal plant, and a standby generator for the Orbal plant.  The City is currently in compliance with all state and federal permit requirements for the discharge of wastewater.
