Expert Training for
Sustainable Pumping

58 Years in the Industry.

Never Sold a Thing.

WATER PUMPING INSTITUTE teaches pumping systems the way they should be taught — as a whole, not as a collection of parts to sell you.

Our Sustainable Pumping methodology is built on one core principle: total system resistance drives energy consumption. That means we optimise everything — pipelines, pumps, valves, fittings, flowmeters, filters and controls — for minimum losses and maximum efficiency across the full life cycle.

We also tackle long-term pipeline efficiency losses head-on, with real case studies in raw water, recycled water, sewage and sea water. And we run the full 25-year Energy Life Cycle Cost numbers on every single component — not just the pump.

Why does that matter? Because Rob Welke, the man behind WPI, has spent 58 years in the water pumping and hydraulics industry and has never sold a single product. No manufacturer ties. No brand agenda. No one paying him to favour their equipment. That makes WPI one of the most independently credentialled training providers on the planet — and it means every word of this course works for you, not for a supplier.

Our Sustainable Pumping courses are the first in the world to teach professionals how to report water pumping emissions data in compliance with:

  • International Sustainability Standards Board (ISSB)

  • Australian Sustainability Reporting Standards (ASRS)

  • European Taxonomy requirements

Real skills. Real tools. Real savings. Backed by 58 years of product-independent expertise.

Ive been very proactive with training and have attended multiple courses through ASME and Hydraulic Institute. The big difference with your course is that it is Practitioner based but presented at Professional Engineer level. There’s no other courses that have this unique combination

Leave Your Course Equipped for The Job

Gain more than just knowledge—walk away with practical tools designed to make a real impact in your daily work. A core part of our training, these exclusive calculators and apps empower you to apply sustainable pumping principles with confidence. Used throughout the course, they become invaluable assets for optimizing efficiency, reducing costs, and making data-driven decisions long after training ends.

Calculator Demonstration

Hydropz - System Design Optimiser

This short demonstration walks through how Hydropz helps engineers and designers make smarter, more sustainable pumping decisions. You will see how the calculator balances pipe capital costs with long term energy use, revealing the true optimal pipe diameter across different life cycles, flow rates, energy prices, and local cost conditions. It is a practical, transparent look at how Hydropz brings sustainable pumping design into a simple, intuitive tool you can use right from your phone.

Meet Your Instructor

Rob Welke has been working in the water pumping and hydraulics industry for 58 years. In that time, he has trained professionals across the globe, built industry-leading tools, and developed a methodology that others are only now catching up to.

He has also never sold a single product — making him one of the most genuinely independent experts in the world.

No manufacturer relationships. No preferred brands. No agenda except yours. When Rob tells you something works, it's because the engineering says so — full stop.

That independence isn't a footnote. It's the foundation of everything WPI does..

Robert has a knack for detail unlike any I’ve encountered. His ability to cut through peripheral detail to target the fundamental causes enable Rob to fulfil his brief in a timely and thorough manner. What I appreciate most about Robert is that he will not compromise on quality and therefore delivers the best possible outcome. Whatever problem you find yourself with, he will find the optimal solution.

Why Choose WPI?

Most training in this industry is delivered by people who sell the equipment they're teaching you about. Rob doesn't. He never has.

58 years. Zero products sold. That's not a gap in his CV — it's the whole point. It means you get training built entirely on engineering merit, with no manufacturer pulling strings in the background.

Practical. Independent. Uncompromising. That's WPI.
