4 The Quarterly The Quarterly New project wins fl ows through as the global desalination and reuse market grows, while drought coninues to grip Cape Town GLOBAL Desal generates 4.4 per cent growth The global desalination market added 4.2 million m3/d in contracted capacity globally during the year to 30 June 2017. The volume of cumulative capacity contracted, including plants contracted or under construction, reached 99.8 million m3/d in the year to 30 June 2017, up by 4.39 per cent on 95.6 million m3/d a year earlier. The growth came both from the utility sector, particularly the Gulf, as well as China, Morocco, and Singapore, and the industrial sector, where stabilisation of oil and gas prices led to upstream and downstream projects. Cumulative global installed (online) capacity rose by 4.4 per cent to 92.5 million m3/d during the year to 30 June 2017, up from 88.6 million m3/d a year earlier. The number of desalination plants worldwide was higher by 389, at 19,372, as of 30 June 2017, compared to 18,983 at 30 June 2016. The fi gures from the annual Worldwide Desalting Inventory, published by GWI DesalData, in association with the International Desalination Association (IDA), show that the desalination market grew for the fourth year in a row, following a slowdown in the mid-2000s. CHILE GS Inima and Claro Vicuna clinch Atacama A consortium of Spain's GS Inima and Claro Vicuna Valenzuela of Chile have won the engineering and construction contract for a desalination plant in Atacama, Chile. The pair beat competition for the reportedly $73 million contract from eight other bidders, made up of international and local companies. The contract with state-owned utility Econssa provides for two years of construction and an operational start date of early 2020. The seawater reverse osmosis plant is expected to have an eventual maximum capacity of 104,000 m3/d, and will serve 70 per cent of the population of Atacama. SOUTH AFRICA Cape Town short-term fi xes due online Temporary desalination facilities will begin supplying Cape Town by December or January 2018, city mayor Patricia de Lille confi rmed in a briefi ng in October. Recycled water from Zandvliet treatment plant will be available from January or February 2018. These short- term solutions are among a ra of tenders for desalination and other water solutions, and supply enhancement initiatives, to prevent Cape Town from running dry. The city could run out of water by March 2018 if collective usage fails to fall to 500,000 m3/d, from 618,000 m3/d. Summer in Cape Town began in November, and the city's dams were at 27.6 per cent usable water as it entered the expectedly drier months. Cape Town council has activated the fi rst of three disaster management phases: it has reduced water pressure in order to cut consumption. Phase two would see water collection points introduced, and the third, most extreme phase, if the city is unable to draw water from its dams, will involve groundwater abstraction and distribution from water points. 19,372 DESAL PLANTS WORLDWIDE
