From the WETEX 2018 website:
Dubai Electricity and Water Authority (DEWA) organises the Water, Energy, Technology, and Environment Exhibition (WETEX) annually.
WETEX shows the latest solutions in conventional and renewable energy, water, sustainability, and conservation. It is a platform for companies to promote their products and services, and meet decision-makers, investors, buyers and interested parties from around the world, to make deals, review the latest technologies, learn about current and future projects, and explore investment opportunities in the region.
