Black & Veatch has been selected for a major desalination project at world's largest copper mine in Chile. The $3.43 billion Escondida Water Supply (EWS) project will provide water to support expansion of mineral production. Black & Veatch explained that its role is leading the engineering design, procurement, field inspection and pre-commissioning for the marine and desalination elements of the EWS project. Once complete the project will deliver 2.5 m3/sec of water to the mine, which majority-owned and operated by BHP Billiton.

The Asian Development Bank (ADB) has approved a $250 million loan to expand the coverage and quality of water supplies to nearly 11 million people in Dhaka, Bangladesh's fast-growing capital city. According to the ADB, Dhaka has been drawing heavily on groundwater, but the current rate of extraction is no longer sustainable with the water table falling by 2 to 3 metres a year. In total the project is expected to cost nearly $675 million and be completed by December 2019.
IDE Technologies has completed work on the 624,000 m³/day Sorek seawater reverse osmosis plant in Israel, which is now fully operational. Located to the south of Tel Aviv, IDE said that the $400 million plant is currently supplying 540,000 m³/day to Israel's water distribution system.

In a recently published White Paper, analysts at Bloomberg New Energy Finance claimed that increasing wastewater charges from £70 to £80 per year, as proposed by Thames Water to pay for its new £4.1 billion 'super sewer', could correspond to a 24% post-tax return on equity invested - more than three times the average return in UK water assets. The analysts noted that the project has been controversial environmentally and also because of the need to raise water bills to finance it.
Municipal authorities in Ho Chi Minh need to issue policies encouraging private investment in wastewater recycling, delegates at a recent seminar in the city were told.

Water pollution caused by nitrates has decreased in Europe over the past two decades, but agricultural pressures are still putting water resources under strain, according to a new report on the Nitrates Directive by the European Commission.
However, the research went on to caution that while the overall trend is positive, nitrates pollution and eutrophication – the excess growth of weeds and algae that suffocates life in rivers and seas – are still causing problems in many Member States.
NanoH2O is to build a 10,000 m2 manufacturing facility in Liyang, China at a cost of around $45 million.
The El Segundo, California based manufacturer of RO membranes for seawater desalination, said that the facility in China will allow it to take advantage of the growing domestic market.
The company added that China represents 20% of the world's population but just 6% of the global fresh water supply, and plans to increase its SWRO capacity three-fold by 2015.
