Following a lift station assessment performed by Valentine for the City of Tempe, the City hired Valentine to perform the design for one of the four lift stations – the Knox Lift Station.  The Knox Lift Station rehabilitation project included rehabilitating the existing wet well, installing new submersible pumps in the rehabilitated wet well, removing below grade discharge piping & moving the piping to above grade for more accessibility, adding a flow meter, replacement of the site PLC, replacement of the RTU cabinet, upgrade to electrical service, and addition of yard hydrant. The design also included bypass pump specifications and sequence of construction to accommodate maintaining the station in service during construction.
