Description Replacement of the influent pump station pumps 1301A, 1302A, and 1303A, Variable Frequency Drive's (VFD's) for these pumps, and the VFD's for pumps 1304A, 1305A, and 1306A. This is inclusive of any piping/electrical modifications that will be required. Total Project Cost: $2,038,000

Justification There are 6 influent pumps and drives currently installed. The 3 pumps listed were installed in 2002 and are at the end of their design life. The pumps have had significant repairs over the past 5-years but they have not extended their design life. They are close coupled centrifugal pumps and be replaced by dry pit submersible pumps that match existing style of the remaining pumps. All drives were part of the original 2002 install and will be replaced with the project. Other work includes piping mods, controls, installation, and SCADA integration.

Budget Impact/Other The existing pumps have increasing maintenance cost and operation costs when they are OOS. New pumps and drives will improve pump efficiency of all pumps, lower power cost and reduced maintenance cost. The current pumps are rated at 10 milllion gallons per day, the newer pumps will be 12 MGD.
