PROJECTS first 10 MGD (37,850 m3 "Utilizing brackish water allows our community to make the most of a previously untapped resource," said Robert R Puente, SAWS president/CEO. "San Antonio continues to invest in new sources to help us meet the city's water needs over the next 50 years, while reducing dependency on the Edwards aquifer." The plant will be located at the existing SAWS Twin Oaks /d) phase is due to come online in 2016. AGENCY APPROVES CAPE RICHE DESALINATION PLANT WITH CONDITIONS Aquifer Storage & Recovery site, which opened in 2004 and has already proved its worth. Last summer, the facility played a major role in staving off severe water restrictions. CITY WITHDRAWS FROM ORANGE COUNTY DESALINATION PLANT The Californian city of San Juan Capistrano has withdrawn from the multi-agency South Orange Coast Desalination Project. The proposed ocean desalination facility would be located at Dana Point and would produce approximately 15 MGD (57,000 m3 25% of the area's potable water demand. The San Juan Capistrano City Council voted by 3-2 on /d). The project would potentially provide up to 20 March 2012 not to spend US$ 23,000 next fiscal year to help cover additional costs of Phase 3 of the project, which includes pumping, testing and treating ocean water at a demonstration plant near Doheny State Beach. A full-scale plant could possibly be completed in 2016. The Municipal Water District of Orange County, is leading the project with remaining partners South Coast Water District, Moulton Niguel Water District, Laguna Beach County Water District and the City of San Clemente. CONSOLIDATED REJOINS ROSARITO DESALINATION PROJECT Cayman Islands company Consolidated Water Co is back on board the Rosarito desalination project in Baja California, Mexico. The 100 MGD (375,000 m3 drinking water demand on both sides of the US/Mexico border. Rick McTaggart, Consolidated CEO, made the announcement /d) seawater plant is designed to supply while reporting on the company's annual report on 15 March 2012. "I am pleased to report that we have negotiated an agreement with one of the other shareholders in our Mexican joint venture, NSC Agua SA de CV (NSC)," said McTaggart, "and we now control 75% of the shares of NSC. MF/RO PLANT MAY BE SANTA CLARITA SALT SOLUTION A microfiltration/reverse-osmosis (MF/RO) advanced wastewater treatment plant is one of several options being considered by the Santa Clarita Valley Sanitation District in California to deal with excessive chloride levels in the wastewater it discharges to the Santa Clara River from its two treatment plants. Other options include reduction of chlorine use by the Western Australia's Environmental Protection Agency on 13 February 2012 announced conditional approval for Grange Resources Ltd's proposal to construct and operate the Cape Riche Desalination Plant. The seawater reverse-osmosis plant will supply 12 million m3 water per year to Grange's Southdown Magnetite Project, an open pit magnetite mine about 90 km east-north-east of Albany. The desalination plant will be located about 5 km west of Cape of Riche, with the seawater intake and pump station 500 m east of Cheyne Inlet. A brine outfall will be located on the south side of Cape Riche. The plant will require: l 25.6 km treated water pipeline from the desalination plant to the mine site; l 5 km seawater transfer pipeline from the intake and pump station to the desalination plant; l 5.7 km brine discharge pipeline from the desalination plant to the outfall location; l 33 kV overhead power lines from the mine site to the desalination plant, and combination overhead/underground cable from desalination plant to seawater intake. VSEP SYSTEM TREATS COLOMBIAN LEACHATE Calfornia-based New Logic Research announced on 8 February 2012 that it had successfully commissioned a landfill leachate treatment system in Colombia using its vibratory shear enhanced process (VSEP) membrane separation system. The VSEP system is operating at a landfill in Buga, a city of 100,000 people located in western Colombia. The 20 ha landfill receives 570 t of household trash daily from 18 municipalities. PILOT VAPOUR-RECOMPRESSION PROJECT TACKLES OIL AND GAS WATER A pilot project to treat produced water from oil and gas operations in southern Saskatchewan, Canada, has been initiated by Purestream Technology of Salt Lake City, USA, using its advanced vapour recompression (AVARA) system. The pilot project, sited in Strathmore, Alberta, is demonstrating its ability to treat and recycle water for potential future use in enhanced gas recovery in the Manville Sandstones and for hydraulic fracturing in the Saskatchewan portion of the Bakken Shale. Late last year, the company performed a successful pilot project near Edson, Alberta that demonstrated AVARA's ability to treat produced and flowback water from several Canadian oil and gas production facilities. CORRECTION introduction of ultraviolet disinfection and greater use of recycled wastewater for irrigation together with the Castaic Lake Water Agency, which provides recycled water to the Santa Clarita Valley. If the MF/RO option were to be adopted, it would also require: l A new 3.5-mile (5.6 km) 12 in (300 mm) pipeline for blending product water with treated wastewater prior to discharge to the Santa Clara River | 26 | Desalination & Water Reuse | May-June 2012 DOOSAN DENIES CYPRUS JOINT VENTURE l Brine disposal either by deep-well injection or a new 37 mile (59 km) 10 in (250 mm) pipeline to an existing trunk sewer.
