Service
Hydraulic Calculations & Pressure Analysis
When you need the numbers behind a design decision, verified independently, this is a focused hydraulic calculation and pressure analysis service: pipe sizing checks, pressure loss calculations, pump duty verification and network capacity analysis.

Not every project needs a full design package. Engineering firms, contractors and municipalities regularly need an independent hydraulic calculation to verify a pipe size, check available pressure at a connection point, size a pump against system curve, or diagnose why an existing network is underperforming.
We provide this as a standalone service, delivered as a clear calculation report with assumptions, methodology and results stated so it can be reviewed, submitted to an authority, or handed to a contractor without ambiguity.
What this includes
- •Pipe sizing and headloss calculations (Hazen-Williams, Darcy-Weisbach)
- •Static and dynamic pressure analysis at any point in a network
- •Pump duty point verification against system curves
- •Water hammer / surge analysis screening
- •Network capacity and bottleneck diagnosis for existing systems
- •Fire flow and residual pressure verification
How we work
- 01
Scope & data
Confirm what needs to be verified and what input data (network layout, demand, elevations) is available.
- 02
Calculation
Hydraulic modeling and calculation using recognised methods, cross-checked against relevant standards.
- 03
Reporting
A calculation report stating assumptions, method and results, ready for internal use, permitting or tender.
Frequently Asked Questions
Can you verify pressure calculations produced by another engineer or firm?
Yes, independent verification of existing hydraulic calculations is a common request, and we deliver a clear report stating whether the original figures hold up and why.
Do you calculate pressure loss for both water supply and sewerage pipework?
Yes, pressure and headloss calculations are provided for pressurised water networks as well as pumped sewerage and rising mains.
How quickly can a standalone hydraulic calculation be turned around?
Turnaround depends on data availability and network complexity; a defined single-point calculation is typically faster than a full network analysis. Timelines are confirmed once the scope is set.
What information do you need from us to start a calculation?
Typically network layout or a schematic, pipe lengths and diameters, elevations, and demand or flow figures. If some of this is missing we can advise on reasonable assumptions or help source it.
