Sydney Water Projects

Our business started with Sydney Water projects… and more than two decades later we are still supplying and installing sewer vent shafts for Sydney Water accredited major and minor works constructors throughout Sydney, Central Coast, Illawarra and the Blue Mountains. Following Sydney Water’s introduction of a new service delivery model in 2021, we are now an official supplier for the North RDC (Confluence Water), South RDC (Delivering 4 Customers (D4C) and West RDC (Western Region Delivery Team (WRDT).

We specialise in the fabrication, delivery and installation of vent shafts to any job site. Our highly skilled team can also assist with project design, tendering and procurement as well as with the completion of pre-works safety, environmental and quality assurance documentation.

A wall-mounted vent shaft

Wall-mounted vent shaft
A wall-mounted vent shaft is the ideal solution for medium and high-density development and in cases where access is severely limited.

These vent shafts can be off-set around eaves and gutters on new buildings. They require fixing to double-brickwork or structural concrete over 150mm in thickness or other approved structure.

Available sizes are DN150, DN225 or DN300mm in diameter to any approved height.

Where there are architectural requirements, there is a choice of complying pipe.

We offer a variety of brackets to use for installation of both enclosed and exposed shafts. We specialise in custom designed stainless steel brackets, including on-site welded plates.

Standard vent shaft design

Custom design vent shaft
Where a standard vent shaft design is unsuitable for a project, we have the expertise and capability to create custom designs.

Our depth of understanding of Sydney Water requirements ensures that we can achieve a compliant design.
