About Capiphon

Capiphon Pty Ltd has been established to take the benefits of Capiphon™ drainage solutions to the World.

We have joined forces with the inventor of Capiphon, Robert Hu, and Greenability Pty Limited, an organisation that has spent almost ten years validating Capiphon’s performance under varying conditions, developing support systems, and training for applications powered by Capiphon.


Our Mission

We understand the significance of water, both in quantity and quality, in a world where population growth, urbanisation, and global warming are bringing unprecedented pressure upon potable water supplies and waste water management.

Capiphon recognises the enormous economic benefit that can come from more efficient water management and from decreased installation costs.  Our mission is to deliver a means of achieving those benefits in all countries around the World.

We will do this by

  • seeking like-minded people and organisations throughout the World to become Distributors
  • providing training and technical support through our Distributors
  • providing a cohesive and concerted marketing approach for our Distributors.

Our People

Terry Mulhall Dip.Val. (Hons), SCV (International), Non-Executive Chairman

Terry has a long history of business development in real estate, as well as in preparing start-ups for both private investment and for IPOs. He has an extensive background in strategic business planning and investment funding, and a long involvement in the thoroughbred industry.

Geoffrey Fenn, BAgrSc, GAICD, Managing Director

Geoffrey has an agricultural science background, and spent the first part of his working life researching the influence of the soil/plant/animal interaction on infertility in sheep and cattle.  His interest in applying a systems approach to problem solving led to his developing disease control and Geographic Information Systems.

He was an early user of the Internet through his association with other GIS scientists around the world, and this took him on another path as the part owner and Technical Director of an online marketing company.  

These past few years have seen him combine his business and agricultural science skills in the development of water management solutions including drainage, groundwater extraction and recharge, and irrigation.  He is also the Managing Director of GreenAbility Pty Limited.

Hu Ming Chun (Robert), Inventor

Robert is a civil engineer who has invented and owned dozens of patents. Robert first had the idea for a drainage system 30 years ago. At the time he was working for the Indonesian government as a contractor building roads. He noticed that the most common reason for the failure of a project was the existence of water and the inability of drains to remove it. He came to the conclusion that conventional drainage systems will always fail eventually because of clogging, and that it was almost always impossible to overcome without completely replacing the drainage. This motivated Mr.HU to develop a better system - Capiphon™.

Noel Merrick, PhD, Graduate Diploma in Data Processing, Senior Consultant

Noel is a senior groundwater modeller, hydrogeologist and geophysicist with 40 years of experience in groundwater science. In May 2009 he retired from the University of Technology, Sydney, where he was Associate Professor and Director of the National Centre for Groundwater Management. He ran courses in Groundwater Modelling, Groundwater Geophysics and Groundwater Policy and Management.

As a researcher, he pioneered methods for resource sustainability quantification and management, particularly using optimisation techniques, and has been engaged in research projects with the Aquaculture, Rice, Cotton and Contaminant CRCs. He was a member of the NSW working group that drafted the State Groundwater Policy documents. Having authored the peer review section of MDBC groundwater flow model guidelines, he has been heavily involved in peer reviewing modelling studies for water supply and for coal mines in NSW, Victoria and Queensland, and he actively builds groundwater models for open cut and longwall mines.

Noel has participated on a number of expert panels as the water expert for the NSW government, in particular the Strategic Inquiry into Potential Coal Mining Impacts in the Wyong LGA. He regularly reviews groundwater resource models for Commonwealth, WA, Qld, Vic and SA government departments. He is also a member of the Murray-Darling Basin Independent Audit Group – Salinity.
