Aquadam Project Overview Unique Planet Pty Ltd PO Box 5872 GCMC Bundall QLD 9726 Ph: Contact: John G Dobozy or John Dobozy Jnr. Freshwater Collection & Storage System
The Aquadam is: –New Innovative Technology –Better way to manage water supplies –Environmentally Sustainable –Reliable and a Guaranteed supply of fresh water –Nationally significant – benefits the economy of Australia. Copyright 2007 Unique Planet Pty Ltd.
Introduction – What is the Aquadam? Unique Planet Pty Ltd, a Queensland-based company, has patented a unique methodology and system for freshwater collection and storage. The revolutionary project is titled “Aquadam” – a flexible, floating dam offshore in the ocean – which will serve as a realistic solution to Australia’s water shortage.

Description – Key Points The Aquadam comprises of a hydro-dynamically shaped flexible reservoirs, which fill with freshwater and float on the surface of the ocean (majority submerged). The Aquadam would ideally be located approximately 2 to 5 kilometers offshore. The flexible Aquadam membranes expand downwards as they fill (to a maximum limit ~ 20m) to store freshwater. Pylons will support the Aquadam structure, allowing it to rise and fall with the tide and ocean swells. Floating platforms situated at the ends of the Aquadam will support the infrastructure, desalinating and treatment plants and energy farms. The water in the Aquadam is piped to multiple well shafts situated on the mainland where it is distributed to the population. Copyright 2007 Unique Planet Pty Ltd.
Project Goals The primary objective of the Aquadam project is to design and construct an integrated system and associated infrastructure for better freshwater management and the collection, storage and supply of a more reliable source of freshwater. The project aims to change the way individuals, industries and governments approach the topic of freshwater supply on a national scale. The project’s aim is not to completely replace current river- based dams in the short-term, but to encourage the adoption of effective, reliable and sustainable water management practices for the long-term. Our long-term plan is to implement this revolutionary innovation firstly in Australia and then globally that will make this a profitable enterprise for Australia.

The Freshwater Issue Currently, the 75,000 existing river-based dams in the world supply water for agriculture, industry and private needs from only one source: RAIN In the past decade, the demand for freshwater has outstripped supply causing devastating droughts. Many scientists and governments believe that for the next couple of generations, water supply will be the dominant issue to be resolved. “Water scarcity is likely to become the greatest single threat to international stability, human health and the global food supply.” (World Resources Institute, 2003) Copyright 2007 Unique Planet Pty Ltd.
The Freshwater Issue (continued…) In Australia, of our 325 rivers, most of the major rivers contain one or more dams throughout their catchment area. As we draw more and more water from these dams (currently 447 dams in Australia), the river systems degrade sometimes beyond repair. We would need to release a greater percentage of water back to the river systems to prevent further catastrophic environmental damage. “60% of the world’s 227 largest rivers are severely fragmented by dams, diversions and canals – leading to the degradation of ecosystems.” (World Water Development Report, UN, March 2003) Copyright 2007 Unique Planet Pty Ltd.
Negative Aspects of River-Based Dams River systems are choked causing adverse effects both upstream and downstream by reduced water flow; High risk of drought when there is low-level of rainfall; Higher levels of dryland salinity; Adverse effects on local flora and fauna; Water temperature altered by the cold water released from the bottom of dam, resulting in disruption of fish spawning and water bird breeding up to hundreds of kilometers downstream; Loss of arable land near riverbeds downstream; Major silting of rivers and delta systems halving the volume of water that can be stored in dams. Dams in the Northern Hemisphere have been shown by a NASA geophysicist to be speeding the Earth’s rate of rotation, as well as altering the Earth’s magnetic field.

Harnessing More Water There is a need for a better system for collecting, storing and managing freshwater than the current practice of capturing water using river-based dams. The Aquadam will harness a larger volume of water by utilizing multiple sources of water. 1.Stormw ater 2.Desalin ation 3.Rainfal l 4.Reloca tion SOURCES OF WATER Copyright 2007 Unique Planet Pty Ltd.
Renewable Energy Several sources of renewable energy will be utilized on-site to power the entire operation of the Aquadam system. WIN D WAVE TIDA L SOLAR Copyright 2007 Unique Planet Pty Ltd.
Renewable Energy (continued…) Using renewable energy sources will promote “green” energy technologies that are suitable for locations away from populated areas. Present projections estimate that renewable energy could generate over 160% of the energy requirements of the Aquadam system. Excess energy generated can be fed into energy grids to supply enough electricity to power approximately 3,000 residential homes. Copyright 2007 Unique Planet Pty Ltd.
Advantages Over River-Based Dams Since the Aquadam does not rely solely on the unpredictability of nature (ie: rainfall), it offers a continuous and guaranteed supply of freshwater, even in times of drought. Access to an abundantly larger source of water, therefore cost per megalitre is reduced. Significant opportunity for large-scale renewable energy projects (eg: wind farms). Positioned in an unpopulated region. Required area is significantly less (river-based dams need minimum 200+ km 2 ; Aquadam = approx. 7 to 35 km 2 ) Contained in a structure that is supported by water (ie: ocean) therefore it is a more “fluid” construction.

Significant Benefits Ability to harness the vast quantity of stormwater currently wasted. Environmental, ecological and social impacts are minimal. Would assist in alleviating the ecological degradation caused by current river-based dams that devastate river systems. By reducing the demand for water from river-based dams, larger volumes of water can be released from reservoirs into the river systems (eg: Murray Darling) to increase the enviro flows and rejuvenate the ecosystems. A guaranteed supply of freshwater will have subsequent benefits relating to a cleaner environment, healthier communities, increased food production, greener cities and lower levels of pollution.

Target Market & Water Licenses The Aquadam will assist governments to guarantee supply of water for: Urban Agriculture (eg: food production) Industry (eg: manufacturing, mining, etc) Enviro flows The security of adequate freshwater supply will be managed with proposed water licenses. “Thirty years ago, dams were wonders of modern engineering; today, dams … have been dubbed eco-killers.” (The Australian Newspaper, July 2003) Copyright 2007 Unique Planet Pty Ltd.
