Electrical and hydraulic upgrades to fifteen sewer pump stations. Thirteen of the pump stations consist of single pumps and local control panel and the remaining two pump stations have dual pumps and local control panels which operate in a duty/standby configuration. Key hydraulic scope items include the provision of overflow storage facilities to the two larger pump stations. A new telemetry system was installed to report real time pump status and alarms to ensure timely responses and reporting.
