New pipeline helps Australian water provider deliver recycled water for industrial uses
Hunter Water, an Australian-based water and wastewater service provider, has commissioned a new advanced water treatment plant and a 5-mile pipeline that will be used to transport recycled water to industrial users in Kooragang Island, New South Wales, Australia.
DENVER, CO, Jan. 6, 2015 -- Hunter Water, an Australian-based water and wastewater service provider, recently celebrated the commissioning of a new advanced water treatment plant (AWTP) and a nearly 5-mile (8-kilometer) pipeline that will be used to transport recycled water to industrial users in Kooragang Island, New South Wales, Australia.
As part of the Hunter Treatment Alliance, CH2M HILL, a global full-service consulting, design, construction, program management, and operations firm, led the concept and detailed design of the Kooragang Industrial Water Scheme (KIWS), a $40-million project to secure future water supplies in the lower Hunter region through industrial water reuse.
The KIWS is the largest recycled water project undertaken by the region, and it will lead to continued growth and economic development for the community. Launched in 2012, KIWS involved diverting 12 million liters of treated effluent from the existing effluent pipeline for Shortland Wastewater Treatment Works to the new AWTP, which uses membrane filtration and reverse osmosis to produce high-quality recycled water to substitute the use of drinking water with water suitable for industrial use.
Recycled water, transported to Kooragang Island via the new pipeline, is benefiting industrial users, such as Orica, currently listed as the region's largest consumer of drinking water. With this project, Orica anticipates dropping to 19th on the list, saving on average 2.3 billion liters of drinking water annually by using recycled water for processing in cooling towers, steam generation, chemical production, equipment cleaning, and employee amenities.
