We estimate
what flows under the city.
Every pipe, manhole, and pump station under Greater Sydney — and increasingly, Australia — costs something to build. We calculate what. First-principles build-ups, fluent in the WSA code and Sydney Water specifications. Water main, sewer, stormwater, and pump station estimating — exclusively. It’s all we do. Turnaround matched to scope.
What we price every week
Six core disciplines, each a deep specialty. From DN100 reticulation to DN1400 trunk mains, from shallow lead-ins to 14-metre sewer, from permanent precast pump stations to IOP poly tanks. View all services →
Move the sliders. Watch the cost.
A simplified demonstration of what our engine does on every job. Real estimates use dozens of variables — soil class, traffic management, authority fees, productivity under constraint. This is enough to show how the logic works.
A full-time estimator is a fixed cost.
Tender volume isn't.
If your tender desk is constantly full, an in-house estimator is the right answer. For everyone else — or for overflow when the desk gets buried — there's WSE. This is the real annual cost of a senior estimator on your payroll, all-in.
The numbers above are Sydney market ranges for an experienced water & sewer estimator, all-in. Actual figures vary by seniority, location, and package structure. The point isn't that in-house is wrong — it's that in-house only pays off above a consistent tender volume. Below that threshold, variable cost wins.
Our specialist estimating services
Whether it's a 1.2km MSCL water main along a live road, a deep sewer subdivision, or a complex pump station with rising main, we've priced it before. We know what it costs because we've costed it from first principles, not pulled from a template library. View all our services →
Three stages. Zero guesswork.
No black boxes. No vague turnaround promises. Here's exactly what happens when you send us drawings — and how fast. Read the full method →
Built by a specialist engineer
WSE Sydney is led by Shoaib Saeed — a civil engineer with over 12 years of international experience across Pakistan, the Middle East and Australia. His exclusive focus on water and sewer infrastructure estimating is what separates WSE from generalist firms.
- B.Eng Civil Engineering — degree-qualified estimator, not a quantity surveyor with a side hustle
- 12+ years specialist experience — water mains, sewer subdivisions, pump stations, stormwater
- WSA code & Sydney Water specifications — fluent in the national code and Sydney Water’s stricter regional specs, down to the Deemed-to-Comply (DTC) drawings within them
- First-principles methodology — every estimate built ground-up, never templated
"Estimating is forecasting reality. Everything else is guesswork dressed up as experience."

Verified signals
from real tenders.
You have a tender.
We acknowledge within 2 hours.
Upload your drawings any time. We acknowledge within 2 hours during AEST business hours, review scope the same day, and agree a realistic delivery window before any work starts. Straightforward estimates within 24 hours. Complex tenders take the time the work demands — supplier quotes, site visits, and peer review where required. Every number defensible.
