The heat generated is conducted down to the lower hemispherical crucible where the constant and rapid intake of seawater is boiled to produce saturated steam. This is then put through a cooling unit, condensed and precipitated as freshwater. “Unlike RO, we use no fossil fuels, only the power of the sun, so the process is net zero, carbon neutral, fully sustainable. It also means that the OpEx (operating expense) costs are significantly reduced, which alongside lower CapEx (capital expenditure) costs, mean that we can produce water at a very competitive cost,” commented Reavley. Solar Water Plc’s Solar Domes provide the solution for governments, water municipalities, agriculturalists and businesses with requirements of generating a supply of freshwater to meet water requirements for growing populations and rapidly expanding socioeconomic development ambitions; whilst current water supplies such as groundwater aquifers continue to decline and degrade. STARTING IN SOUTH WEST ASIA Solar Water’s first commercial scaled dome is under construction for the eco-city of NEOM in Saudi Arabia and is due to be completed and operational by the end of 2021. Saudi Arabia is the world’s largest desalinator of water, with about 22% of the global market, “so it was a real mark of confidence to have them as our first contract”. In fact, the clients were pleased to be pioneering partners with Solar Water, with the first of its kind technology to help shape the future of water desalination in NEOM. Commenting on the project, His Excellency Abdulrahman Al- Fadli, Saudi Arabia’s Minister of Environment, Water and Agriculture, said, “NEOM’s adoption of this pilot supports Saudi Arabia’s sustainability goals, as outlined in the country’s National Water Strategy 2030, and is fully aligned with the sustainable development goals set out by the United Nations.” Nadhmi Al-Nasr, CEO of NEOM, added, “Easy access to abundant seawater and fully renewable energy resources means NEOM is perfectly placed to produce low cost, sustainable fresh water through solar desalination. This type of technology is a powerful reminder of our commitment to supporting innovation, championing environmental conservation and delivering exceptional liveability. Working together with the Ministry of Environment, Water and Agriculture we can expand the implementation of this technology beyond NEOM.” 50
WATER & WASTEWATER ASIA | MAY/JUNE 2021 Gavin van Tonder, head of Water Philippines, Australia, India, Pakistan, agriculture, industry and tourism at NEOM, also said, “We’re really Bangladesh and Sri Lanka.

In Asia, there are active project conversations in Vietnam, authorities, industry and others. “Our Solar Domes create fresh water on an industrial scale for diverse applications in urban development, a zero-carbon impact by 2030; if you are serious about a cost-effective solution for water provision; then we at Solar Water have the solution,” said Reavley.
