Mechanical & Electrical Renewal Project

 

The Sylvania Sewerage Pump Station is located within a residential catchment of the Sutherland Sewerage System. The existing pumps had exceeded their design life and needed to be replaced. The wastewater pumping station is located in a low level area that is at risk of flooding. Planned modifications were needed to protect the dry well and all electrical equipment from flood water.
The upgrade has provided reliable and maintainable pumping units, minimising the risk of failures due to flooding at the site and making the pumping station compliant with the current safety standards.

 
PET was engaged to undertake the following renewal activities:
♦  Replacing the existing 1972 transfer pumps with newer more efficient dry mounted submersible pumps
♦  Replacing rising main and pump isolation valving as well as relocating bypass connection
♦  New dry well ventilation shaft and instrument hatches
♦  New station unloading driveway and bypass valving bund
♦  Flood mitigation works including elevating a new switchboard on a new platform and a perimeter bund wall to prevent water ingress
♦  Replacement of internal access ladders as well as other works for compliance with client standards
♦  Installation of new switchboard and complete re-wiring of the site

Complete Project Responsibility

PET’s scope included maintaining station operation throughout the site construction works, including night time shut downs, bypass pumping, transfer tankering and electrical cut over to new control equipment. Given the proximity of the station to residential housing and a function centre, community engagement and planning each stage of the project with stakeholders was paramount.
