Who We Are


WaterSelect P/L is the name of a small South Australian company dedicated to improving the efficiency of urban and rural engineered water systems.

The company established this website in early 2001 as a means of providing a range of information and tools aimed at supporting the efforts of all persons and organisations sharing these same goals.

The Authors


Richard and David have a combined total of over 75 years of professional experience working as hydrologists and water systems investigators. In the late 1980’s they recognised the need for new approaches to water systems that incorporated improved information on all elements of the local regional water cycle and, where possible, enabled multiple objectives to be incorporated into the single system design. They commenced working together on the WaterCress model and have continuously developed and used the model in many of the high-profile innovative water schemes in South Australia. These have included Mawson Lakes and the Parafield Airport Scheme. The model is also used by the State Government for water allocation planning, in particular the impact of farm dams in rural catchments.

Greater efficiencies envisaged will only become mainstream practice after the present ‘water industry’ has been reformed. Such desired reforms will inevitably reduce the present emphasis on the (assumed) economies of large scale, single purpose water and will result in the establishment of a ‘new generation’ of smaller, lower cost, multiple objective, customised water systems. Customers of water systems will have a far greater ability to select their water systems – hence our choice of WaterSelect as our name.

Our aim is to provide the tools to encourage the development of an integrated water supply system which incorporates all sources of water available in the urban environment

To date, the information on the website mainly relates to the WaterCress model. The WaterCress model was developed to simulate and assess the performance of trial water systems designed to achieve greater efficiencies.
