The Westconnex Wattle Street, was a key infrastructure project in Sydney which aimed to help ease congestion, create jobs and connect communities.

Stormwater Drainage & Electrical Work:

The package awarded to Subterra Civil consisted of;

  • 54 precast pits 
  • Over 330m of stormwater drainage piping, both 375mm and 450mm stretching

For the duration of the project, the Wattle Street tunnel remained open for construction traffic access, allowing the WestConnex Project to continue moving forward.
