In 2006 Whelans completed the construction of the electrical / mechanical works for the largest waste water pump station on the Sunshine Coast.

The pump station caters for most of Caloundra and includes two 250 kW submersible pumps.

Whelans provided the switchboard with variable speed drives, PLC control system, 450 mm pipework within the pump station, surge vessel, air compressors, and two 500 kVA standby generator sets to operate the pump station during power failures.

The project included the upgrade of two additional major pump stations within Caloundra.
