jerseyThe U.K.’s first desalination plant, La Rosière in Jersey, is undergoing major upgrades. ACWA services Ltd, which is part of a leading water and wastewater corporation, will nearly double the plant’s capacity, reduce operational costs, and implement security measures for periods of low rainfall. The turnkey solution will include the redesign and expansion of the existing seawater and reverse osmosis process streams, a new dual media filter, next generation reverse osmosis membranes, pre-treatment systems and related equipment. Once the plant is operational, it will produce 10,800 cubic metres of water a day, with the capacity to produce 15,000 cubic metres of water daily (upon future expansion).

In the water-starved city of Chennai, India, the Tamil Nadu state government is setting up a third desalination plant.  Located in Nemelli, the plant will use reverse osmosis to produce 150 million litres of water a day—contributing to Chennai Metrowater’s current distribution of 550 million litres of water to the region on alternate days [1] The German development bank, KfW, is financing the plant’s construction, and a team from the bank will soon visit Chennai to finalize details.  It is expected that the project will take 30 months to complete after the construction contract has been awarded.

In Horizon City, Texas, STW Resources has completed improvements on the Horizon City Municipal Utility District plant.  The facility, which now uses a reverse osmosis concentrator...

Singapore

Singapore’s five million inhabitants currently consume an average of 1.5 million cubic metres of water a day.[1] To meet the needs of a growing population, the island-nation’s Public Utilities Board (PUB), the national water agency, has announced plans to build a fourth desalination plant. The plant will produce 136,400 cubic metres of water daily.[2]  Reports suggest that the plant will be located near water stressed zones.   

Apart from desalination, Singapore’s PUB draws freshwater from three other sources—local catchment areas, imported water, and reclaimed water.[3]  PUB has also created a water conservation programme that targets the private and public sectors.  Since 2003, per capita domestic water consumption has fallen from 165 litres per day to 150 litres, and further reductions aim for an average of 140 litres by 2030.[4]

californiaIn San Diego, during California’s crippling drought, the International Desalination Association has kicked off its 2015 World Congress.  The event is focused on desalination and water reuse, and brings together delegates from across the world every two years.  In the words of the IDA Secretary General, Patricia Burke, the purpose of the event is “to address the growing demand for a sustainable source of fresh water in response to population growth, economic expansion, degradation of existing resources, and the effects of climate change.” The location is fitting, as San Diego is home to the nearly finished Carlsbad Desalination Plant—the largest in the Western hemisphere.

Wildfire walla wallaFor the first time since 2013, the U.S. entered “National Preparedness Level 5”—a term that signifies “all agency fire resources” across the country are nearly exhausted and struggling to fight fires.  At present, vast infernos are raging across Northern California and the Northwest.[1]  The severe drought and heat across the region is creating one of the worst “wildfire summers” on record.  Last week, fire officials reported the situation could worsen “with a new round of wind and heat.”[2]  The New York Times reports that more acres have burned this year so far – 7.2 million as of last week – than in each of the previous 10 years.[3]  Alaska has suffered the great majority of these conflagrations, but California is currently dealing with the worst of them.

In California, the revised ‘Ocean Plan’ requires desalination plants to use subsurface ocean intake systems unless a study determines it to be infeasible.[1]  For the proposed desalination facility at Huntington Beach, a report has concluded that a subsurface ocean intake is financially infeasible.  The report, completed by an Independent Scientific and Technical Advisory Panel (ISTAP), was jointly commissioned by Poseidon Resources and the California Coastal Commission.  The report calculates an estimated cost of $1,000 (USD) extra per acre-foot of desalinated water for a subsurface intake, which brings the total cost to approximately $2,661 (an open-ocean intake would cost a total of $1,639 per acre-foot).  Construction for the subsurface intake would also take five to seven years longer than an open-ocean intake.

Antigua and BarbudaIn the West Indies, the twin island state of Antigua and Barbuda has depleted its reservoirs.  While water rationing has been in place for more than a year, the country’s 90,000 inhabitants are now entirely dependent on desalination plants, surface water, and ground water.[1] Water management is reported as the nation’s principal environmental concern.  Droughts occur in the tropical nation every five to ten years—and in 1983-1984, authorities had to import water from other countries to make up for the deficit.[2]
