A contract to build and operate a new desalination water plant in North Side has been awarded to Consolidated Water Company, the owner and operator of Grand Cayman’s six other desalination plants.
The plant will be off Frank Sound Road, North Side, and will be capable of producing almost 2.5 million US gallons of water per day.
Under the terms of the contract, CWCO are required to guarantee 2.14 million US gallons per day to its customer, the Water Authority of the Cayman Islands.
The plant is expected to be constructed and operational within 12 months and will increase Grand Cayman’s total desalination production capacity by about 35 per cent to approximately 9 million US gallons per day.
In June, Water Authority Deputy Director Tom van Zanten said locating the plant in North Side was in line with its policy of having plants in different locations to reduce the risk of a major service outage in the event of natural disasters.
Mr. van Zanten said the contract demanded the plant be able to withstand winds up to 150mph. It must also contain an emergency generator so water can be produced in the immediate aftermath of a natural disaster, he added.
Like the existing plants, the new facility will use reverse osmosis to convert seawater into drinking water.
According to CWCO Vice President of Engineering Gerard Pereira, the plant will benefit from use of the Calder DWEER® energy recovery device, which can cut electricity consumption by about 30 per cent compared to conventional turbine technology.
The plant will also include a partial second-stage brackish water desalination unit, allowing it to ensure water quality in excess of World Health Organisation standards.
CWCO incorporated in the Cayman Islands in 1979 and now operates water production and distribution facilities in Barbados, Belize, and the Bahamas. Its affiliate, Ocean Conversion (BVI) Ltd, also produces and distributes water in the British Virgin Islands and is constructing a desalination plant in Bermuda.
