Pumps & Pump Stations33
For pump designers & installers — pick the right pump, check NPSH and dodge cavitation, dead-heads and burnt-out motors.
View the pack →
Pipe Hydraulics32
For hydraulic designers — size pipes, nail friction loss and velocity, and stop water hammer before it splits a main.

Electrical Power & Cable23
For electricians on water & pump sites — size cable to AS/NZS 3008, check volt-drop and arc-flash safety.
View the pack →
Water Treatment23
For treatment & process engineers — size filtration, disinfection, dosing and RO to hit your water-quality targets.
View the pack →
Irrigation Advanced Design20
For irrigation designers — zoning, mainlines/submains and emitter uniformity that actually perform in the field.
