Sydney Water Projects

SVSR began with a Sydney Water project. More than two decades later we continue to supply high quality sewer vent shaft services for Sydney Water contractors across Sydney, the Central Coast, Illawarra and the Blue Mountains. Our robust processes ensure we meet all compliance requirements – and that we deliver on time, in full, and to specification.

Official supplier to Sydney Water

Following Sydney Water’s introduction of a new service delivery model in 2021, SVSR is now an Official Supplier for the three Regional Delivery Consortia in the north, south and west of Greater Sydney:

  • North RDC – Confluence Water
  • South RDC – Delivering for Customers (D4C)
  • West RDC – West Region Delivery Team

“We’re maintaining continuity. We’re now officially endorsed to continue to supply our high-quality sewer vents for Sydney Water projects, just as we’ve done for decades.” ~ Kylie Ridding, SVSR Managing Director

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

Our compliance documentation includes Safe Work Method Statements (SWMS), Inspect and Test Plans (ITP), Corrosion Methodology and WSHE paperwork.

Deemed to Comply vent shaft

Deemed to Comply (DTC) sewer vent shaft

We use 316 grade stainless steel to manufacture our DTC sewer vent shafts. They have a design life of 50-60 years even in the most extreme corrosive environments.

We offer standard sizes of DN150, DN225, DN300 and custom sizes including DN400 and DN450.

A wall-mounted vent shaft

Wall-mounted vent shaft

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

These sewer 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 compliant pipe.

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

Custom design vent shaft

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

With a complete understanding of water authority requirements, we offer effective and cost-efficient design compliant with Sydney Water and industry standards.
