Specifically, current planning primarily includes the following components. o Construct a new plant lift station with three pumps equipped with variable frequency drives. o Upgrade the existing carrousel basin to have a 1.94 MGD capacity. The basin has sufficient volume for the capacity increase, but the mechanical aerators will need to be changed from 100 horsepower to 150 horsepower. o Construct two new 68' diameter final clarifiers. o Construct a new RAS/WAS pump station. The station will have three (3) RAS pumps and two (2) WAS pumps. All of the pumps will be equipped with variable frequency drives. o Expand the existing chlorine contact basin to provide sufficient volume to meet a required 20-minute detention time at peak flow. As part of the chlorine contact basin improvements, construct a new non-potable water system pump for the plant. o Make improvements to the existing chlorination facilities to meet TCEQ facility and safety requirements. o Make improvements to the Parshall Flume to provide for continuous totalized flow readings on the plant effluent. o Repurpose the existing final clarifiers to sludge holding tanks. Towards this effort blower will need to be constructed to provide air to the diffuser that will be installed into the tanks. o Construct a new sludge transfer pump station to pump sludge from the holding tanks to the proposed new belt filter press. o Construct a new 1.0-meter belt filter press. Also, construct two (2) small conventional drying beds to provide backup for an event when the 1.0-meter belt filter press might be down for maintenance. o Site improvements will be made including asphalt and concrete pavement as well as site drainage. o The project will also include all of the related piping, valves, electrical, instrumentation, and other miscellaneous work for a complete functional project.
