business | 6 | Desalination & Water Reuse | February-March 2014 ContRaCt&tenDeRneWs Veolia wins Az Zour MED in Kuwait Veolia Environnement announced on 13 January 2014 that its Sidem subsidiary had won the contract to build the seawater desalination plant at the Az Zour North complex in Kuwait for € 320 million. Sidem will build the 486,400 m 3 /d multi-effect distillation (MED) plant, while its partner in the engineering, procurement and construction contract, Hyundai Heavy Industries, will build the 1,500 MW power station. All the electricity and water will be purchased by the Kuwaiti government for 40 years. Work will begin before the end of 2013 and is scheduled for completion by the end of 2016. The Az Zour desalination plant will account for approximately 20% of Kuwait's installed capacity. Veolia is also in the start-up phase for the Az Zour South seawater desalination plant, which will have a daily capacity of 136,000 m 3 /d. Bechtel contract for Escondida project BHP Billiton has contracted Bechtel to provide engineering, project management and construction services for the water supply to the Escondida copper mine in the Atacama Desert of northern Chile. The project includes construction of a seawater desalination plant, to be supplied by Doosan Heavy Industries & Construction (D&WR November-December 2013), at the Caleta Coloso port and the piping and electrical infrastructure needed to transport the water to the mine, 185 km away and 3,100 m above sea level. The mine is operated by Minera Escondida, in which BHP Billiton owns a majority stake. Bechtel will construct the 220,000 m³/d desalination plant and undertake the engineering and construction of two 42 in (1.07 m) diameter pipelines that will run between the port and the mine and the related infrastructure, which includes four high- pressure pumping stations, associated electrical substations, and 114 km of high-voltage transmission lines along the pipeline route. Bechtel also will provide construction-management services for the marine works associated with the project. Desalitech, developer of the closed-circuit desalination (CCD) system, is to supply a zero liquid discharge (ZLD) advanced wastewater treatment system for a pesticide plant in Gujarat, India. Desalitech is working for UPL Environmental Engineers Ltd (UPLEEL). The Desalitech system will process 200 m 3 /d of industrial wastewater as part of a treatment process designed to minimize disposal costs and environmental impact by virtually eliminating liquid waste. Desalitech's CCD reverse osmosis (RO) solution will be a key element in the plant's ZLD system, cutting the costs and energy consumption of downstream components by as much as 50%. "Desalitech's technology provides superior operational efficiency by greatly reducing effluent waste while using less energy than any other RO solution on the market," said Santhosh Nair, managing director of UPLEEL. "It is a smart investment that will pay for itself in six months. But beyond obvious cost benefits, Desalitech solutions provide a degree of control and flexibility that we haven't had before." Desalitech Ro 'will repay in 6 months' H 2 O Innovation lands three Alberta contracts H 2 O Innovation Inc announced on 14 January 2014 recent contracts totaling Can$ 6.5 million (US$ 5.93 million) in Western Canada's energy sector. These new jobs bring the company's order backlog for water treatment projects to Can$ 17.9 million (US$ 16.34 million) as of 13 January 2014. Two major contracts have been awarded by a leading independent energy company engaged in the exploration, development and production of natural gas and oil in North America. These will see H 2 O Innovation design, build and commission a potable water treatment package as well as a wastewater treatment package for a 2,300-person workers camp in Northern Alberta. The potable water plant, which includes provision of raw water pumping, filtration using cartridge filters, ultrafiltration and reverse osmosis, as well as chlorination prior to storage in an above-ground bolted steel potable water storage tank, will produce 575 m 3 /d of fully treated potable water. To complement the potable water, H 2 O Innovation will supply a membrane- bioreactor wastewater-treatment plant having a capacity of 517.5 m 3 /d and consisting of raw wastewater pumping, anoxic and aerobic tanks, membrane tanks, disinfection by ultraviolet light and discharge to an engineered disposal field. "The award of these contracts from a major player in the oil & gas industry is a pledge of confidence because it is the second mandate given to us by this client just after the delivery of two similar units last fall," said Frédéric Dugré, president and CEO of H 2 O Innovation. A third contract has been awarded by an international company operating in Alberta, which specializes in in-situ oil sands production. This contract will see H 2 O Innovation design, build and commission a membrane-based water treatment package located within the owners' central processing facility to treat well water for domestic use in the administration and maintenance buildings, laboratories and garage wash bay, as well as supplying the safety showers and eye-wash stations.
