Introduction

Wonthaggi Desalination Plant

·         The Victoria’s desalination Plant is designed to remove soluble salts and minerals from sea and ocean water.

·         Intended so it is suitable for drinking, irrigation and industrial uses

·         Alternative source in areas that have limited amount of fresh water

·         Providing a reliable and safe supply of water to growing communities

Purpose

·         Victoria needs a desalination plant because of the population growth, climate change and drought

·         The desalination plant is being put in place to guarantee the reliability of our future water supply

·         A major benefit of the desalination plant is that it can continue to deliver high quality drinking water, even if we don’t get enough rain

Location

·         Victoria’s desalination plant is located just outside the town of Wonthaggi, having Bass Coast as its main location

·         Three other locations were also listed: Surf Coast, Port Phillip Bay and Western Port

Location of Desalination Plant

Establishment



Construction at Site

·         Construction of the Victoria’s Desalination Plant began on the 6^th of October 2009

·         The Victorian Government announced its intention to develop a seawater reverse osmosis on June 19^th 2007

·         A great deal of planning was required before they began building

·         Expecting to be finished before December 2011.

Organization

    ·         The Victorian government, the department of sustainability and the Environments Capital Project Division made an agreement with the company AquaSure, who is the main organization.

    ·         They agreed to finance, design, build, operate and maintain the Victoria’s desalination plant.

Design

Progress of Victoria's Desalination Plant

·         It is based on the concept of a ‘green line’, featuring a modern living roof that has been fully designed to integrate the built form of the landscape and makes the plant barely visible from all public viewing points

·         The roof will be completely covered with living indigenous vegetation to camouflage the plant

·         Provide acoustic protection, corrosion resistance and thermal control, to reduce maintenance needs.

Size

    ·         Comprise of 29 buildings that would take up 38 hectares of the total 263 hectare on site

    ·         The remainder of the area will be seen as one of the largest single ecological restoration project in Victoria

    ·         It will restore and enhance the natural habitat

    ·         Create a new coastal park for the future generations to enjoy.

Process

·         The Victoria’s Desalination Plant uses a process called Reverse Osmosis, which is a filtering process

·         From the ocean it passes through two levels of initial filtration to remove most of the large and small particles

·         Roughly 40% of the water that goes through the desalination plant comes out as fresh drinking water and the other is pumped back into the ocean

·         This water cycle is monitored to make sure that our environment is not harmed in any way

Reverse Osmosis Desalination

Areas affected

·         Victoria’s desalination plant will be the largest in Australia

·         Capable of supplying approximately one third of Melbourne’s annual water usage from a source that is entirely independent of rainfall

·         It will provide up to 150 billion litres of water a year to Melbourne, Geelong, and regional towns in South Gippsland and Western Port

Distribution of Water Supply

Benefits

·         As well as being a source of water that isn’t dependent on rainfall, there are other benefits towards the community

·         It provides up to 4750 full-time equivalent jobs during construction

·         $1 billion economic boost to Victoria during construction

·         Fibre optic cable will be installed with the power supply which will provide communication services to local communities

Workers

Energy

·         It requires approximately 90MW of electricity to operate, distributing 150GL of water a year

·         100 per cent of this will be produced from renewable energy

·         This is equivalent to a standard 4-star fridge, which would use about the same amount of energy as the desalination plant per household every day.

Cost

     ·         The project will cost approximately $3.5 billion dollars

     ·         Operating costs are to be charged by a private firm over a 25–30 year period and are estimated to be around $1.5 billion

     ·         Includes labor, replacement of membranes, chemicals costs and energy

Timeline

·         19 June 2007- The Victorian Government released its Water Plan project

·         30 July 2009- Winning bidder for construction, AquaSure was announced

·         6 October 2009- Construction commenced

·         4 February 2010- First sections of the new pipeline are laid

·         December 2011- Production and related operations expected to commence

·         2035-2045- Contract for the operation of the plant expected to expire
