Ravenhall Outfall Sewer Stage 1E

Background:

City West Water set out on their Corporate Plan for 2019-20, which included an huge 5 year capital expenditure plan to support in growing CBD & Western corridor sewer network.

This corporate plan includes a 5 year $556m (at nominal values) capital program that is heavily influenced by the need to deliver growth-related network projects. In particular, the program is dominated by sewer growth projects as CWW extends its trunk sewerage infrastructure into both:

• Developing greenfield areas – for example, outlet sewers for Tarneit West, Mt Atkinson and Ravenhall
• Capacity upgrades for the inner city and CBD – for example, CBD sewerage upgrade Stage 2 and Stage 3.
• Remaining capital expenditure relates to ongoing investment to support projects catering for:
  • New connections in our service area
  • CWW asset renewal program – which is being designed to effectively manage risk and avoid longer term deterioration of asset performance”

Project Scope:

Asset Owner:  Greater Western Water

Contractor: Califam Constructions Pty Ltd

Global Pipe worked with Viadux and Califam Constructions to assess the project requirements and create a seamless transition from planning and specification to construction and project delivery.
Deep trench installation of up to 6m – Califam’s Constructions teams equipment made light work of the hard rock soil conditions.
