What we Are

GreenAbility Pty Limited is an established research and development company engaged in unlocking the potential of a revolutionary drainage technology (Capiphon™) to deliver enhanced water management. 
GreenAbility has conducted a number of R&D trials over the last several years in water management technologies such as

  • general drainage
  • sports field and race track drainage
  • roadside and railway drainage
  • building protection & damp proofing
  • Water Sensitive Urban Design
  • storm water management
  • rainwater harvesting
  • groundwater extraction &recharge
  • flood mitigation
  • cost and water efficient sub-surface irrigation

Our Mission

GreenAbility recognises the singular importance 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.

GreenAbility is moving to re-shape the nature and effectiveness of total water management in this country and Globally.


Our People

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.  An interest in systems approach to problem solving led to his developing disease control and Geographic Information Systems. 

These past few years has 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 the Managing Director of GreenAbility Pty Limited.



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. He retired in May 2009 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.
