The Mini-Hydro Development Scheme endeavours to harness excess hydraulic energy at five sites in the Melbourne water supply system. The mini hydros represent a minor part of Melbourne Water’s goal to reduce operational energy costs and expansion of energy generation in Melbourne.

Jaydo was awarded all five mini-hydro projects, with scope comprising civil, mechanical and electrical works. The five sites include works within operational sites at the following locations: Boronia, Wantirna, Cardinia, Dandenong and Mount Waverly.

The works at these sites involve the following:

• Civil works for installation of new site main switchboard and kiosk substation
• VEDN accredited conduit installation for electrical works including trenching, installation of conduits and pits for electrical cables
• Full reinstatement, including gravel access track and hardstand area
• Modification to existing MSCL pipework
• Valves, bypass flow control
• Flowmeters, dismantling joints
• Corrosion protection
• Post & panel retaining wall, galvanised mild steel access stairs & hand railing
