Water main estimating, done right.

DICL (Ductile Iron Cement Lined) is socket-and-spigot pipe with rubber ring joints — fast install, common up to ~600mm diameter. MSCL (Mild Steel Cement Lined) is welded steel pipe — used for large diameters (typically 600mm+), high-pressure applications, and long trunk mains. MSCL needs cathodic protection, specialist welders, and coating systems — all of which generalist estimates often miss. See our dedicated MSCL water main estimating page.

Every water main estimate is built against the WSA Code (Water Services Association of Australia) as the national standard, then layered with Sydney Water Specifications where applicable. Sydney Water DTC (Deemed-to-Comply) drawings sit within this framework and dictate specific configurations for handle bars, encasement, manhole types, and approved materials. We cross-reference your design against all three layers before pricing — so we catch items that generalist estimators routinely miss. This is core to our specialist methodology. Get details on our DTC handle bars and concrete encasement pages.

From 63mm PE service connections through to 1800mm+ MSCL trunk mains. We estimate at every scale and pipe class — residential subdivision (typically 100mm – 250mm DICL or PVC), commercial developments (250mm – 600mm DICL), and major infrastructure (600mm – 1800mm+ DICL or MSCL).

Yes — fire service mains are part of our standard water estimating service. Including dedicated fire mains for commercial developments, fire hydrants to AS 2419 requirements, booster valves, and authority connections. We allow for the specific fittings and testing requirements fire mains require.

Every enquiry is acknowledged within 2 hours during business hours. After reviewing your scope, we agree a realistic deadline with you upfront — every time. Smaller jobs can turn around quickly; larger trunk main projects and complex subdivisions take longer to do properly. The key thing is: we tell you exactly when to expect it, and we deliver on that promise.

Absolutely — we estimate water mains for projects across Australia. While our Sydney Water Specifications expertise is one of our deepest specialties, our first-principles methodology adapts to any authority's requirements. From NSW regional councils to Melbourne Water, Brisbane Urban Utilities, Water Corp WA, SA Water, and beyond.

PDF drawings are preferred (long sections, plan views, typical details, specifications). We also accept DWG/DXF, ZIP archives, and image files. Use the upload field on our contact form for files up to 10MB. For larger files, email us a WeTransfer or Dropbox link.

Yes — plant and machinery costs are included as standard. Excavators (typically 5-20 ton for water mains), rollers, tippers, watercarts, and shoring equipment are all costed at current market rates. For quick plant rate calculations, try our free machine hire rate calculator.
