Potable and non-potable water lines, process water reticulation, plant feed, cooling water, compressed air and gas service lines, and zone-isolated reticulation across copper, stainless steel, HDPE, PE, PEX and aluminium. Installed to AS/NZS 3500 and your engineering spec, with backflow protection where the service crosses a hazard rating.
Process water work usually starts with a deadline (new plant going in), a problem (failing reticulation), or a compliance flag (identification audit or backflow exposure). Here’s the version we hear most.
Engineering has a new piece of plant coming in and needs feed water (potable or otherwise) at a defined connection point by a target date. Pressure, flow rate and isolation already spec’d.
Burst frequency on aged galvanised or AC pipe is rising. Each repair takes a line out, slows production, and the next one is a question of when not if. The line needs replacing, not patching.
Auditor or council has flagged unclear identification on existing non-potable or process water lines. Site needs lines tagged and identified per AS 1345 before sign-off.
Sydney Water or council has advised the site needs zone or site-level backflow because a hazard rating applies. A boundary or zone backflow device is required to keep contamination off the drinking water network.
We do industrial process services: potable, non-potable, process, cooling and plant feed water, plus compressed air and gas service lines. Copper, stainless, HDPE, PE, PEX, PVC, aluminium. Backflow installation, testing and certification where the hazard rating requires it. Specialist and medical gas systems and trenchless renewal sit outside our scope. If the job crosses into one of those, we’ll tell you straight on the site walk and refer to a specialist trade.
Most industrial water work falls into one of four scopes. Each has a different design, install footprint and certification path. Here’s how we approach each one.
Site mains, internal ring mains, drinking water to amenities and food-grade tap points. Designed for pressure, flow and isolation, with backflow protection where the service crosses a hazard rating into a process zone.
Recycled water, cooling water, washdown lines and process water reticulation. Clearly identified per AS 1345 with purple-lilac banding, flow-direction arrows and content labels, so there is no chance of cross-contamination with potable services.
Dedicated water service to a specific piece of plant. Isolation at the takeoff, instrumentation tappings for pressure and flow, gauges where engineering wants visibility. Lockable isolation for shutdowns.
Extending or re-zoning an existing reticulation network, replacing failed sections of aged steel or AC pipe, capping and isolating abandoned runs so they don’t become a dead-leg or a corrosion risk to the live system.
Wetherill Park, Smithfield, Eastern Creek, Penrith. The Western Sydney industrial corridor runs the gamut from 1970s galvanised mains through to modern HDPE drops put in last year. Most factory sites are working with what’s there, not a greenfield install.
Our approach: survey what exists, mark up the live services properly, isolate before cutting, and replace into materials that will outlast the next reorganisation of the factory floor. We work around production, not over the top of it.
The accounts that prove it: Brickworks, Austral Bricks, Bowral Bricks, Austral Masonry, Yates Manufacturing (20+ years), Knauf Gypsum (15 years), Veolia Environmental Services (10 years), Penrith RSL Club. Long tenure on industrial reticulation is how this business runs.
Industrial process work is paperwork as much as pipework. The order is the same on every site: review, induct, agree the materials, install in the agreed window, commission and hand over the records the job needs.
Walk the route, review existing as-builts (where they exist), identify hazard ratings on each zone, and assess the condition of any service we’ll be tying into. Anything unclear gets flagged before we quote.
Safe Work Method Statement and certificates of currency lodged ahead of the install date. Site induction completed for every operative attending. PPE matched to the site requirement.
Confirm material selection (copper, stainless, HDPE, PE, PEX or aluminium) against the engineering spec. Isolation strategy agreed with the site so production knows exactly what’s down, when, and for how long.
Install during the agreed window. Lock-out tag-out at every isolation. Pressure test on every new section as part of commissioning. No live cuts on a process line without sign-off.
Pressure-test certificates where required, and updated as-built drawings on request. 12-month workmanship warranty applies to the install. Invoice on agreed account terms.
Material selection is half the install. We work across the standard industrial range and match the material to the duty: temperature, pressure, the medium it carries and the access constraints of the route. Anything specialised (high-purity, food-grade stainless polish) is sourced through trade.
Direct answers on standards, materials and certification. If your question isn’t here, ring the workshop and we’ll talk through it.
Ring the workshop with the deadline, the duty and the connection points, or email the drawings and the engineering spec through. We’ll come back with a route, material recommendation and a fixed quote on letterhead.
