The Rottnest Island DaisyOn the shores of Rottnest Island in Western Australia, solar energy will soon help to power an existing desalination facility that is undergoing major upgrades. [1] In the spring of 2017, the Rottnest Island Water and Renewable Energy Nexus Project (WREN) will realize its objective to deliver electricity and drinking water for the island at a lower cost and with reduced emissions—by using renewable energy and displacing existing diesel-powered generators. [2]  The WREN Project will add 600 kW of solar power to an existing 600 kW wind turbine that was installed in 2004.  It will also implement a smart control system that will maximise the use of solar and wind energy when it is most abundant, and store treated water for times when renewable energy is not available. [3]

Basalt columns on the Penghu Islands In Penghu County, Taiwan, the “the Canary Islands of the Orient,” a local official has requested that the central government expand the capacity of a desalination plant that is scheduled to open in 2018.  Last week, Penghu County Magistrate, Chen Kuang-fu, made his appeal during a meeting with the deputy head of the country’s Water Resources Agency. Chen requested an increase of 6,000 cubic metres per day, as opposed to the scheduled 4,000 cubic metres a day.

Penghu County includes almost 100 islands formed from lava of volcanic eruptions roughly 17 million years ago. A quarter of these islands are inhabited, and renowned for their breath-taking, geologically distinct cliffs and beaches, magnificent ocean views, celebrated temples, and traditional Chinese-style homes surrounded by coral walls.

In the Middle East, the intergovernmental political and economic union known as the Gulf Cooperation Council (GCC) is set to increase its desalination capacity by 40% within the next five years, in order to meet the region’s growing demand for drinking water.    GCC member states—Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates—currently use around 3,300 million Imperial gallons of potable per day (MIGD; 15 million m³/d) and this number is expected to increase to 5,200 MIGD by 2020 (23 million m³/d).

In Jakarta, the Indonesian megalopolis of Java, city officials are planning to develop five seawater desalination projects in the Thousand Island archipelago that is just north of the city. The Thousand Islands, also known as Kepulauan Seribu, consists of a string of 128 small islands in the Jakarta Bay, which are surrounded by clear, calm waters and white-sand beaches. Of these islands, 13 are fully developed for public use, and among them, Karya, Kelapa, Harapan, Tidung, and Untung Jawa will become home to new plants.1 The construction will be completed by next year.

Nanoporous carbonScientists at the Leibniz Institute for New Materials (INM) in Saarbrücken, Germany are further developing an emerging desalination method.  The process, referred to as capacitive deionization (CDI), extracts ions from water using electrodes, generating clean water and ions that have been enriched on the electrodes.[1] This process removes salts and heavy metals and, uniquely, it does not use conventional water treatment methods that rely on chemical reactions or sophisticated filtering methods.

In addition to desalination, Professor Volker Presser, head of the Energy Materials Group at INM, explains that emissions from power plants can be used to produce electricity using CDI—as long as the emissions are present (i.e. dissolved) in the water as ions— by taking advantage of the temperature change between the charge and discharge of the electrodes.

The Namibian government has made progress towards finalising a deal to purchase the country’s sole desalination plant.1 Since September 2014, a Cabinet-appointed government negotiating team has been working with the privately-held company, Areva Resources, to purchase the plant, located in the Erongo region, 30km from the capital, Swakopmund. The Omdel water-supply system and the Kuiseb River have long supported the region’s coastal towns and businesses, however, their volumes have been diminishing over the years. In 2009, water shortages stopped the Erongo region’s uranium mining production for the first time.

The Areva plant currently supplies water exclusively to the Husab and Rössing mines; and will continue to support these mines after officials finalise its purchase. Sugnet Smith, of Areva Resources Namibia, has reported that the company is not able to reveal the plant’s purchase price prior to the conclusion of negotiations. Assuming the sale concludes smoothly, the Namibia Water Corporation (NamWater), owned by the government’s Ministry of Agriculture, will soon assume responsibility for distributing at least 11 million cubic metres of water annually; however, the plant is capable of producing 20 million cubic metres.3

South Gippsland Hills, Victoria | Credit: Ian Rolfe PhotographyIn Australia, officials are developing a water plan that will possibly restart Victoria’s $4 billion seawater desalination plant.[1]  Located on the continent’s southeastern coast, Victoria’s mainland (230,000 square kilometres) is defined by rugged coastline and vast expanses of ancient and protected forests.  A lack of rainfall since July 2014 has brought the ravages of drought to the terrain, parching vast expanses of land (in the north and the west) and diminishing water storage levels.  Parts of western and south-eastern South Australia have received the lowest rainfall on record; and by December, several rivers in Victoria will stop flowing altogether.

jerseyThe U.K.’s first desalination plant, La Rosière in Jersey, is undergoing major upgrades. ACWA services Ltd, which is part of a leading water and wastewater corporation, will nearly double the plant’s capacity, reduce operational costs, and implement security measures for periods of low rainfall. The turnkey solution will include the redesign and expansion of the existing seawater and reverse osmosis process streams, a new dual media filter, next generation reverse osmosis membranes, pre-treatment systems and related equipment. Once the plant is operational, it will produce 10,800 cubic metres of water a day, with the capacity to produce 15,000 cubic metres of water daily (upon future expansion).

Singapore

Singapore’s five million inhabitants currently consume an average of 1.5 million cubic metres of water a day.[1] To meet the needs of a growing population, the island-nation’s Public Utilities Board (PUB), the national water agency, has announced plans to build a fourth desalination plant. The plant will produce 136,400 cubic metres of water daily.[2]  Reports suggest that the plant will be located near water stressed zones.   

Apart from desalination, Singapore’s PUB draws freshwater from three other sources—local catchment areas, imported water, and reclaimed water.[3]  PUB has also created a water conservation programme that targets the private and public sectors.  Since 2003, per capita domestic water consumption has fallen from 165 litres per day to 150 litres, and further reductions aim for an average of 140 litres by 2030.[4]

In California, the revised ‘Ocean Plan’ requires desalination plants to use subsurface ocean intake systems unless a study determines it to be infeasible.[1]  For the proposed desalination facility at Huntington Beach, a report has concluded that a subsurface ocean intake is financially infeasible.  The report, completed by an Independent Scientific and Technical Advisory Panel (ISTAP), was jointly commissioned by Poseidon Resources and the California Coastal Commission.  The report calculates an estimated cost of $1,000 (USD) extra per acre-foot of desalinated water for a subsurface intake, which brings the total cost to approximately $2,661 (an open-ocean intake would cost a total of $1,639 per acre-foot).  Construction for the subsurface intake would also take five to seven years longer than an open-ocean intake.

Antigua and BarbudaIn the West Indies, the twin island state of Antigua and Barbuda has depleted its reservoirs.  While water rationing has been in place for more than a year, the country’s 90,000 inhabitants are now entirely dependent on desalination plants, surface water, and ground water.[1] Water management is reported as the nation’s principal environmental concern.  Droughts occur in the tropical nation every five to ten years—and in 1983-1984, authorities had to import water from other countries to make up for the deficit.[2]
