Piping & Mechanical Installation

Quality mechanical and piping installation from a team that understands industrial work, fabrication and site conditions.

At QSW, we install the mechanical systems that keep water treatment plants, pump stations, industrial facilities and civil infrastructure operating safely and efficiently.
We are based in Gippsland and work across Melbourne, regional Victoria and interstate on larger projects.

Our background is in fabrication, welding and plant installation. We approach every project with the same focus: clear planning, accurate installation, and reliable performance once the system is running.
Clients come to us when they need pipework manufactured and installed properly, equipment aligned correctly and mechanical systems that meet engineering requirements without complications.

Why Mechanical Installation Needs Experience

Mechanical and piping systems are unforgiving. If something is installed incorrectly, it will cause issues later.
Leaks, vibration, breakdowns, shutdowns, rework and safety incidents all come from poor installation.

We work across water and wastewater plants, pump stations, stormwater infrastructure and industrial facilities.
These environments demand tradespeople who understand how mechanical and pipeline systems operate, not just how they fit together on paper.

We support:

Pump station installation
Water and wastewater treatment mechanical installation
Commercial and industrial mechanical services
Civil contractors needing pipework installation
On site welding and repairs
Mechanical maintenance and shutdown work

Planning

A complete one stop shop with the ability to manufacture and install structural mechanical and piping components. Experienced Project Management capable of coordinating projects from initial stages of the projects to completion and handover. Inhouse drafting capable of generating workshop detailed drawings and site installation and layout plan well-maintained Installation plant and equipment ability to assist with design walkways, platforms, access ways, pump stations and piping.

Site Setup and Safety

We follow ISO-aligned safety systems and meet all on-site requirements for rigging, lifting, mechanical isolation and confined-space entry. Most of our work is inside water, wastewater and industrial environments, so safety controls are essential.

Installation

Our team installs:

Mild steels, stainless steels, and Mild Steel Concrete Lined Piping
Valves, meters, pumps and mechanical equipment
Pipe supports, fabricated steel components and brackets
Stormwater, wastewater and water-infrastructure pipe systems

Every joint is aligned. Every weld is compliant. Every support is fitted correctly.

Testing and Quality Checks

QSW’s systems of work are ISO – certified, and we complete and provide to our clients a range of QA details including hydrostatic testing, mechanical inspection checks, welding QA data , as-built verification and ITP/ITR documentation. Mechanical installation only lasts long-term when the QA process is followed from start to finish.

Handover and Commissioning Support

We supply as-built information, test results and installation documentation. Our supervisors stay available to assist commissioning teams onsite and hand over back to operations.

What We Work On

Pump Stations

Installation of pumps, manifolds, valves, pipework and associated mechanical systems.

Treatment Plants

Mechanical installation, pipework upgrades, equipment changeouts and support for water and wastewater facilities.

Industrial and Commercial Facilities

Mechanical systems for new plant, replacement pipework, maintenance and repair work.

Civil and Infrastructure Projects

On site mechanical installation across stormwater, water and wastewater pipeline works.

Shutdowns and Maintenance

Mechanical maintenance, repairs, welding, pipe replacements and emergency mechanical work.

Fabrication and Installation

Our workshop fabricates pipe spools, supports, structural components and stainless steel items which are then delivered and installed onsite.

Where We Work

We operate throughout Melbourne, Gippsland, the Latrobe Valley, Geelong, Ballarat and Bendigo.
Interstate services are available for water and wastewater infrastructure projects in NSW and South Australia.

If you are looking for mechanical installation, commercial mechanical services in Melbourne, pipeline installation or a mechanical contractor with fabrication capability, we can help.
