Southeast Regional Wastewater Treatment Plant Expansion

Southeast Regional Wastewater Plant expansion was developed in two phases. The Phase 1 component included an expansion of the disinfection system (the new chlorine contact chamber) that provides the final step in the treatment of water to be beneficially reused through irrigation. The chlorine contact chamber was designed and constructed in a period of nine months, bringing the capacity up to 7.4 mgd. The second phase of construction consisted of major facility expansion and upgrades that brought the facility up to 11.0 mgd capacity. This design was fast-tracked, completed in approximately six months. The major components included in the new construction were expanded headworks, flow splitter box, equalization tank, aeration basin, aerated sludge storage tanks, gravity belt sludge thickener, clarifiers, sand filter system, chlorine contact chambers, emergency generators and an access road. In addition, the facility construction included major renovation/replacement of the electrical systems, a complete upgrade of the in-plant Control and Monitoring system, which will integrate with the County’s proposed Supervisory Control and Data Acquisition (SCADA) system. The project also included an access road relocation and a new leachate collection system that improved the control of the groundwater levels in the western area of the Lena Road Landfill containment system. The new 2.6 mg equalization basin was constructed to aid in the treatment of landfill leachate discharged to the wastewater treatment facility.
