Document Description
The proposed project will address future capacity needs at the existing wastewater treatment plant over the next 20 years. The proposed project will result in an increase in the design capacity from a maximum dry weather flow of 1.05 million gallons per day (mgd) to 1.7 mgd. The increase in primary and secondary treatment capacity will be achieved by significantly increasing aeration in the aeration and polishing ponds (ponds #1 and #2 respectively), improving mixing in the aeration pond and replacing the existing headworks with a new facility. Hydraulic upgrades consisting of yard piping and inlet/outlet modifications will be performed to maintain the required minimum 2 feet of freeboard in all ponds at peak flows. The proposed modifications to the existing aeration systems will increase the wastewater treatment plant capacity and will reduce total suspended solids (TSS) and biochemical oxygen demand (BOD) concentrations in the effluent produced.
