Aruba
The island of Aruba has a large (world's largest at the time of its inauguration)[citation needed] desalination plant, with a total installed capacity of 11.1million US gallons (42,000m3) per day.[citation needed][18]
The Millennium Drought (1997–2009) led to a water supply crisis across much of the country. A combination of increased water usage and lower rainfall/drought in Australia caused state governments to turn to desalination. As a result, several large-scale desalination plants were constructed (see list).
Large-scale seawater reverse osmosis plants (SWRO) now contribute to the domestic water supplies of several major Australian cities including Adelaide, Melbourne, Sydney, Perth and the Gold Coast. While desalination helped secure water supplies, it is energy intensive (≈$140/ML). In 2010, a Seawater Greenhouse went into operation in Port Augusta.[19][20][21]
A growing number of smaller scale SWRO plants are used by the oil and gas industry (both on and offshore), by mining companies to supply slurry pipelines for the transport of ore and on offshore islands to supply tourists and residents.
Bahrain
Completed in 2000, the Al Hidd Desalination Plant on Muharraq island employed a multistage flash process, and produces 272,760m3 (9,632,000cuft) per day.[22] The Al Hidd distillate forwarding station provides 410 million liters of distillate water storage in a series of 45-million-liter steel tanks. A 135-million-liters/day forwarding pumping station sends flows to the Hidd, Muharraq, Hoora, Sanabis, and Seef blending stations, and which has an option for gravity supply for low flows to blending pumps and pumps which forward to Janusan, Budiya and Saar.[23]
Upon completion of the third construction phase, the Durrat Al Bahrain seawater reverse osmosis (SWRO) desalination plant was planned to have a capacity of 36,000 cubic meters of potable water per day to serve the irrigation needs of the Durrat Al Bahrain development.[24] The Bahrain-based utility company, Energy Central Co contracted to design, build and operate the plant.[25]
Barbados
In 1994–1995 the island of Barbados experienced a severe 1 in 50 year severe drought[26] that knocked much of the island's drinking water supply offline including the country's sole major hospital in the capital-city Bridgetown.[27] An agreement was negotiated with General Electric's Ionics Inc.[28] to build a reverse osmosis desalination plant on the south western coast of the island capable of supplying 20% of the islands population. The plant began operating within 15 months and was officially commissioned February 2000. Currently many cruise ships purchase water from Barbados due to its good quality.[29]
Thorium Power Canada, with its affiliate, DBI Chile, have proposed plans to build a 10 MW demonstration thorium reactor in Chile to power the 20 million litre/day desalination plant. All land and regulatory approvals are currently in process.[34]
China
China operates the Beijing Desalination Plant in Tianjin, a combination desalination and coal-fired power plant designed to alleviate Tianjin's critical water shortage. Though the facility has the capacity to produce 200,000 cubic metres (7,100,000cuft) of potable water per day, it has never operated at more than one-quarter capacity due to difficulties with local companies and inadequate local infrastructure.[35]
In 2014, the government confirmed the reservation of a 10-hectare site at Tseung Kwan O for the construction of a reverse-osmosis desalination plant with an initial output capacity of 50 million cubic metres per annum. Plans include provisions for future expansion to an ultimate capacity of 90 million cubic metres per annum, which will meet about 10 per cent of Hong Kong's fresh water demand. Detailed feasibility studies, preliminary design and a cost-effectiveness analysis are planned to be completed by 2014. A commissioning date of 2020 is envisaged.[39]
Cyprus
A plant operates in Cyprus near the town of Larnaca.[40] The Dhekelia Desalination Plant uses the reverse osmosis system.[41]
Egypt
Dahab Desalination Plants Dahab 3,600m3/day completed 1999. The facility in the South Sinai is being expanded to produce 15,000m3/day[42]
Hurgada and Sharm El-Sheikh Power and Desalination Plants

Zaafarana Power and Desalination
Remelah Desalination Plant
As of May 2022, Egypt had a total of 82 desalination plants with a combined capacity of 917,000 cubic meters per day.[43]
India has two large desalinization plants for domestic uses, the Minjur Seawater Desalination Plant[47][48] and the Nemmeli plant, both in Chennai with 100 million litres per day (MLPD) capacity.[49][50] For industrial uses, 100 MLPD plant was set up in Dahej, Gujarat in 2022 with an investment cost of approximately ₹900 crore (US$110million).[51]
Iran
An assumption is that around 400,000 m3/d of historic and newly installed capacity is operational in Iran.[52] In terms of technology, Iran's existing desalination plants use a mix of thermal processes and RO. MSF is the most widely used thermal technology although MED and vapour compression (VC) also feature.[52]
Iranian project Persian Gulf Water Transfer WASCO will see the biggest Desalination project in the world based in Bandar Abas with 1.6 million capacity. There are three phases, phase 1 will be fully complete by 2024.[53][54]

Israel
Israel Desalination Enterprises' Sorek Desalination Plant north of Palmachim was foreseen to provide up to 26,000 m³ of potable water per hour once it went online in June 2013 (that is ca. 228 million m³ when projected on an entire year).[55] Once unthinkable, given Israel's history of drought and lack of available fresh water resources, with desalination Israel can now produce a surplus of fresh water.[56]
By 2014, Israel's desalination programs provided roughly 35% of Israel's drinking water, about 50% in 2015, and it is expected to supply 70% by 2050.[57] As of May 29, 2015 more than 50 percent of the water for Israeli households, agriculture and industry is artificially produced.[58]
Existing Israeli water desalination facilities[59]
(expansion up to 150 million m3/year possible)[68]
Additional desalination plants supply the entire freshwater needs of the city of Eilat by desalinating a mix of brackish well water and seawater. Similar plants exist in the Arava and the southern coastal plain of the Carmel range.[69]
Kazakhstan
MAEK-Kazatomprom LLP operates sea water desalination plant in Aktau, Mangystau from 1967. Now its power comes to 74,000 m3/day. Earlier it was a part of combined combinate with Nuclear plant and gas electric power stations. Also in Aktau there is membrane technology water desalination plant Kaspiy, which power comes to 20,000 m3/day
Kuwait
Kuwait does not have any permanent rivers. It does have some wadis, the most notable of which is Wadi Al-Batin which forms the border between Kuwait and Iraq.
Kuwait relies on water desalination as a primary source of fresh water for drinking and domestic purposes. There are currently more than six desalination plants.[70] Kuwait was the first country in the world to use desalination to supply water for large-scale domestic use. The history of desalination in Kuwait dates back to 1951 when the first distillation plant was commissioned.[71]
Malta
Malta has four reverse osmosis desalination plants in Pembroke, Cirkewwa, Ghar Lapsi and Hondoq and in 2022 they produces about 22 mln m3 of water, accounting for 64% of total water production in the country.[72]
Norway is a country with little to no problems with water access. Over 99% of the population's water supply comes from fresh water sources such as lakes, tarns, rivers and ground water. There are however three water works in Norway taking use of desalination of sea water and all of them are located in the county of Nordland, only providing around 500 people with water.[79]
Oman
A pilot seawater greenhouse was built in 2004 near Muscat, in collaboration with Sultan Qaboos University, providing a sustainable horticultural sector on the Batinah coast.[80]
As of 2007, there was one seawater desalination plant in Deir al-Balah in the Gaza Strip, built in 1997–99 with funding by the Austrian government. It has a capacity of 600 cubic metres (21,000cuft) per day and it is owned and operated by the Coastal Municipalities Water Utility. At least initially, the operating costs were subsidized by the Austrian government. The desalinated water is distributed to 13 water kiosks.[84][85]
Desalination of seawater is expected[by whom?] to become more important in the future through a long-planned regional desalination plant that would provide desalinated water using the piped water network throughout the entire Gaza strip. For over 20 years, a major desalination plant for Gaza has been discussed. The Palestinian Water Authority has approved a $500 million facility. Israel supports it and has quietly begun to offer Palestinians desalination training.[86] In 2012 the French government committed a 10 million-euro grant for the plant. Arab countries, coordinated by the Islamic Development Bank, committed to provide half of the necessary funds, matching an expected European financial commitment. The European Investment Bank provides technical assistance.[87]
Another major problem is that desalination is very energy-intensive, while the import of fuel to produce the necessary electricity is restricted by Israel and Egypt. Furthermore, revenues from drinking water tariffs are insufficient to cover the operating costs of the envisaged plant at the current tariff level.[88]
A water desalination plant was recently inaugurated by Pakistan's Minister for Ports and Shipping at the port city of Gwader on 01 Jan, 2018. This is one of the biggest of its kind plant in Pakistan. On the inauguration day the Pakistan's Minister for Ports and Shipping said in his address,
To drive this point home, he mentioned that this plant (which can hold 5 million gallons of water) will provide 254,000 US gallons (960m3) of clean potable drinking water per day – at Rs. 0.8 per gallon.[89]

Spain
Lanzarote is the easternmost of the autonomous Canary Islands, which are of volcanic origin. It is the closest of the islands to the Sahara desert and therefore the driest, and it has limited water supplies. A private, commercial desalination plant was installed in 1964 to serve the whole island and enable the tourism industry. In 1974, the venture was injected with investments from local and municipal governments, and a larger infrastructure was put in place in 1989, the Lanzarote Island Waters Consortium (INALSA)[101] was formed.
Barcelona 200,000m3/day (operator Degremont) El Prat, near Barcelona, a desalination plant completed in 2009 was meant to provide water to the Barcelona metropolitan area, especially during the periodic severe droughts that put the available amounts of drinking water under serious stress.
While mainland Sweden is able to depend on long rivers, many thousands of lakes and groundwater, the sunny and dry nature of the Baltic Sea archipelago has led to a deficit of water on the island of Gotland.[110] The island has two desalination plants for brackish water from the Baltic Sea, one built 2016 in Herrvik with a capacity to produce 480 m3/day,[111] and another one with a capacity of 7 500 m3/day in Kvarnåkershamn.[112]
Taiwan
In February 2021 a desalination plant with a daily capacity of 13000 tons was built as an answer to a water emergency. The plant supposed to support semiconductor production in greater Hscinchu area from Nanliao.[113]
Trinidad and Tobago
The Republic of Trinidad and Tobago uses desalination to open up more of the island's water supply for drinking purposes. The country's desalination plant, opened in March 2003, is considered to be the first of its kind. It was the largest desalination facility in the Americas, and it processes 28,800,000 US gallons (109,000m3) of water a day at the price of $2.67 per 1,000 US gallons (3.8m3).[114]
This plant will be located at Trinidad's Point Lisas Industrial Estate, a park of more than 12 companies in various manufacturing and processing functions, and it will allow for easy access to water for both factories and residents in the country.[115]
United Arab Emirates
The UAE relies has over 70 desalination plants, and relies on desalination for 42% of its drinking water.[116] The hosts some of the world's largest desalination plants, which are listed in the table above.[117] The include the Jebel Ali desalination plant in Dubai, a dual-purpose facility, uses multistage flash distillation and is the largest in the world, capable of producing 2,227,600m3 (2,913,600cuyd) of water per day. Al Taweelah RO is the world's largest reverse osmosis desalination plant, producing 909,200m3 (1,189,200cuyd) of water per day.[118]

United Kingdom and Crown dependencies
The first large-scale plant in the United Kingdom, the Thames Water Desalination Plant, was built in Beckton, east London for Thames Water by Acciona Agua.[120] It was built in 2010 at a cost of £250m. The plant provides up to 150 million litres of drinking water each day (150,000 cubic metres) – enough for nearly one million people.
Jersey
The desalination plant located near La Rosière, La Corbière, Jersey, is operated by Jersey Water. Built in 1970 in an abandoned quarry, it was the first in the British Isles.
The original plant used a multistage flash (MSF) distillation process, whereby seawater was boiled under vacuum, evaporated and condensed into a freshwater distillate. In 1997, the MSF plant reached the end of its operational life and was replaced with a modern reverse osmosis plant.
Its maximum power demand is 1,750kW, and the output capacity is 6,000 cubic meters per day. Specific energy consumption is 6.8 kWh/m3.[121]
United States
Texas
There are a dozen different desalination projects in the state of Texas, both for desalinating groundwater and desalinating seawater from the Gulf of Mexico. However, currently there are no seawater desalination plants earmarked for municipal purposes.[122][123]
El Paso: Brackish groundwater has been treated at the El Paso, Texas, plant since around 2004. It produces 27,500,000 US gallons (104,000,000L; 22,900,000impgal) of fresh water daily (about 25% of total freshwater deliveries) by reverse osmosis.[124] The plant's water cost–largely representing the cost of energy–is about 2.1 times higher than ordinary groundwater production.
Carlsbad: The Claude "Bud" Lewis Carlsbad Desalination Plant was constructed at a cost of $1 billion by Poseidon Resources and was the largest desalination plant in the United States when it went online December 14, 2015.[127] It produces 50 million gallons a day to 110,000 customers throughout San Diego County.
Concord: Planned to open in 2020, producing 20 million gallons a day.[125]
Monterey County: Sand City, two miles north of Monterey, with a population of 334, is the only city in California completely supplied with water from a desalination plant.
Santa Barbara: The Charles Meyer Desalination Facility was constructed in Santa Barbara, California, in 1991–92 as a temporary emergency water supply in response to severe drought.[128][129] While it has a high operating cost, the facility only needs to operate infrequently, allowing Santa Barbara to use its other supplies more extensively.[130][131] The plant was re-activated in the spring of 2017.
Florida
RO production train, North Cape Coral RO Plant
In 1977, Cape Coral, Florida became the first municipality in the United States to use the RO process on a large scale with an initial operating capacity of 3 million gallons per day. By 1985, due to the rapid growth in population of Cape Coral, the city had the largest low pressure reverse osmosis plant in the world, capable of producing 15 MGD.[132]
As of 2012, South Florida has 33 brackish and two seawater desalination plants operating with seven brackish water plants under construction. The brackish and seawater desalination plants have the capacity to produce 245 million gallons of potable water per day.[133]
The Tampa Bay Water desalination project near Tampa, Florida, was originally a private venture led by Poseidon Resources, but it was delayed by the bankruptcy of Poseidon Resources' successive partners in the venture, Stone & Webster, then Covanta (formerly Ogden) and its principal subcontractor, Hydroanautics. Stone & Webster declared bankruptcy June 2000. Covanta and Hydranautics joined in 2001, but Covanta failed to complete the construction bonding, and then the Tampa Bay Water agency purchased the project on May 15, 2002, underwriting the project. Tampa Bay Water then contracted with Covanta Tampa Construction, which produced a project that failed performance tests. After its parent went bankrupt, Covanta also filed for bankruptcy prior to performing renovations that would have satisfied contractual agreements. This resulted in nearly six months of litigation. In 2004, Tampa Bay Water hired a renovation team, American Water/Acciona Aqua, to bring the plant to its original, anticipated design. The plant was deemed fully operational in 2007,[134] and is designed to run at a maximum capacity of 25million US gallons (95,000m3) per day.[135] The plant can now produce up to 25million US gallons (95,000m3) per day when needed.[136]
Arizona
Yuma: The desalination plant in Yuma, Arizona, was constructed under authority of the state Colorado River Basin Salinity Control Act of 1974 to treat saline agricultural return flows from the Wellton-Mohawk Irrigation and Drainage District into the Colorado River. The treated water is intended for inclusion in water deliveries to Mexico, thereby keeping a like amount of freshwater in Lake Mead, Arizona and Nevada. Construction of the plant was completed in 1992, and it has operated on two occasions since then. With a full capacity of 73 million gallons per day of permeate water, it is the largest desalination plant in the US. The plant has been maintained, but largely not operated due to sufficient freshwater supplies from the upper Colorado River.[137] An agreement was reached in April 2010 between the Southern Nevada Water Authority, the Metropolitan Water District of Southern California, the Central Arizona Project, and the U.S. Bureau of Reclamation to underwrite the cost of running the plant in a year-long pilot project.[138]

Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. Many seagoing ships and submarines use desalination. Modern interest in desalination mostly focuses on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few water resources independent of rainfall.
Water supply and sanitation in Singapore are intricately linked to the historical development of Singapore.

Access to water in Singapore is universal, affordable, efficient and of high quality.
Solar desalination is a desalination technique powered by solar energy. The two common methods are direct (thermal) and indirect (photovoltaic).
A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment, concentration of contaminants, and the reclamation of dissolved minerals. An average modern reverse osmosis plant needs six kilowatt-hours of electricity to desalinate one cubic metre of water. The process also results in an amount of salty briny waste. The challenge for these plants is to find ways to reduce energy consumption, use sustainable energy sources, improve the process of desalination and to innovate in the area of waste management to deal with the waste. Self-contained water treatment plants using reverse osmosis, called reverse osmosis water purification units, are normally used in a military context.

Water supply and sanitation in Saudi Arabia is characterized by challenges and achievements. One of the main challenges is water scarcity. In order to overcome water scarcity, substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment. Today about 50% of drinking water comes from desalination, 40% from the mining of non-renewable groundwater and only 10% from surface water in the mountainous southwest of the country. The capital Riyadh, located in the heart of the country, is supplied with desalinated water pumped from the Persian Gulf over a distance of 467 km. Water is provided almost for free to residential users. Despite improvements, service quality remains poor, for example in terms of continuity of supply. Another challenge is weak institutional capacity and governance, reflecting general characteristics of the public sector in Saudi Arabia. Among the achievements is a significant increases in desalination, and in access to water, the expansion of wastewater treatment, as well as the use of treated effluent for the irrigation of urban green spaces, and for agriculture.
The Victorian Desalination Plant is a water desalination plant in Dalyston, on the Bass Coast in southern Victoria, Australia. The project was announced by Premier Steve Bracks in June 2007, at the height of the millennium drought when Melbourne's water storage levels dropped to 28.4%, a drop of more than 20% from the previous year. Increased winter-spring rains after mid-2007 took water storage levels above 40%, but it was not until 2011 that storages returned to pre-2006 levels.
A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure fluid to such a process is to transfer the waste pressure to a low pressure stream using a pressure exchanger.

The Sydney Desalination Plant also known as the Kurnell Desalination Plant is a potable drinking water desalination plant that forms part of the water supply system of Greater Metropolitan Sydney. The plant is located in the Kurnell industrial estate, in Southern Sydney in the Australian state of New South Wales. The plant uses reverse osmosis filtration membranes to remove salt from seawater and is powered using renewable energy, supplied to the national power grid from the Infigen Energy–owned Capital Wind Farm located at Bungendore.
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances, and is used in industrial processes and the production of potable water. RO retains the solute on the pressurized side of the membrane and the purified solvent passes to the other side. The relative sizes of the various molecules determines what passes through. "Selective" membranes reject large molecules, while accepting smaller molecules.
Water supply and sanitation in Israel are intricately linked to the historical development of Israel, because rain falls only in the winter, and largely in the northern part of the country. Irrigation and water engineering are considered vital to the country's economic survival and growth. Large scale projects to desalinate seawater, direct water from rivers and reservoirs in the north, make optimal use of groundwater, and reclaim flood overflow and sewage have been undertaken. Among them is the National Water Carrier, carrying water from the country's biggest freshwater lake, the Sea of Galilee, to the northern part of the Negev desert through channels, pipes and tunnels. Israel's water demand today outstrips available conventional water resources. Thus, in an average year, Israel relies for about half of its water supply from unconventional water resources, including reclaimed water and desalination. A particularly long drought in 1998–2002 had prompted the government to promote large-scale seawater desalination. In 2022, 85% of the country's drinkable water was produced through desalination of saltwater and brackish water.
The Adelaide Desalination plant (ADP), formerly known as the Port Stanvac Desalination Plant, is a sea water reverse osmosis desalination plant located in Lonsdale, South Australia which has the capacity to provide the city of Adelaide with up to 50% of its drinking water needs.
Australia is the driest habitable continent on Earth and its installed desalination capacity has been increasing. Until a few decades ago, Australia met its demands for water by drawing freshwater from dams and water catchments. As a result of the water supply crisis during the severe 1997–2009 drought, state governments began building desalination plants that purify seawater using reverse osmosis technology. Approximately one percent of the world's drinkable water originates from desalination plants.

The Minjur Desalination Plant is a reverse osmosis, water desalination plant at Kattupalli village, a northern suburb of Chennai, India, on the coast of the Bay of Bengal that supplies water to the city of Chennai. Built on a 60-acre site, it is the largest desalination plant in India. Construction works were carried out by the Indian company IVRCL and the Spanish company Abengoa, under the direction of the Project Manager Fernando Portillo Vallés and the Construction Manager Juan Ignacio Jiménez-Velasco, who returned to Europe after the inauguration of the plant to work on renewable energy projects. Originally scheduled to be operational by January 2009, the work on the plant was delayed due to Cyclone Nisha in October 2008, which damaged a portion of the completed marine works and destroyed the cofferdam meant for the installation of transition pipes. The trial runs were completed in June 2010 and the plant was opened in July 2010. Water from the plant will be utilised chiefly for industrial purposes such as the Ennore Port and North Chennai Thermal Power Station. However, during droughts, water from the plant will be supplied to the public, serving an estimated population of 1,000,000.
