| [텍사스] 95만㎥/일 규모의 담수화 플랜트 계획 종합평가 추진
미국 텍사스 지역에서 95만㎥/일의 담수화 프로젝트 및 동일한 위치에 발전소를 건설하기위한 사전 검사 평가 연구 프로젝트에 MWH Global사가 선정되었다.
이 프로젝트는 캘리포니아에서 추진되는 Carlsbad 및 Huntingdon Beach 지역의 담수화 프로젝트로 모두 18만9천㎥/일(50 MGD) 규모의 기존 플랜트보다 훨씬 큰 규모이다.
MWH사는 2012년 9월 발표된 RFQ 제안 신청의 전체 64개 내외국인 회사 중의 16개 팀중의 하나로 이번 검사 평가 항목에는 플랜트 위치, 효과적인 물수송 체계, 동력원 검토, 염분수 배출의 안전한 처리, 기타 환경적 영향, 경제성 및 건설기간 등에 대한 검토 등이 포함된다.
이번 평가 연구에는 20개월이 소요되며 이 연구결과로 향후 이 지역에 필요한 물수요인 250MGD의 담수화 프로젝트 추진이 예상되고 있다.

MWH selected for 250 MGD Texas desalination study
MWH Global has been selected by the Guadalupe-Blanco River Authority (GBRA) in Texas, USA, to carry out the feasibility study to assess the development of ocean water desalination of up to 250 MGD (950,000 m³/d) as a regional water supply, including the option of co-located power generation facilities.
This would dwarf the Carlsbad and Huntingdon Beach projects, currently progressing in California, which will each be only 50 MGD (189,000 m³/d).
MWH was one of 16 teams representing 64 national and international firms to initially respond to GBRA's request for qualifications (RFQ), which was publicly posted in September 2012. The Texas General Land Office agreed to partner with GBRA and will contribute toward funding the study.
"This feasibility study will have to consider and evaluate many factors, such as plant location, most effective and efficient water conveyance system, fuel source, safe brine disposal and other environmental issues, economic issues and construction timelines," said James L Murphy, GBRA executive manager for water resources and utility operations.
"We anticipate that this feasibility study could take up to 20 months to complete," said Gary Asbury, GBRA's manager of project engineering and the client project manager for water on the IWPP. "While we will have to wait to see what the feasibility study determines, it is anticipated that the fully expanded project could yield up to 250 MGD of desalinated water to serve the region."
In order to develop the RFQ, GBRA consulted the director of the Texas Sustainable Energy Research Institute, Dr Les E Shephard, who also holds the Robert F McDermott Distinguished Chair in Engineering at the University of Texas at San Antonio.
Shephard, who will serve as client project manager for the overall project, said the independent water and power project could potentially generate as much as 3,000 MW of electricity at full capacity that will help mitigate impacts from growing power needs across Texas. Already power officials are predicting potential "brown-outs" across the state in the face of prolonged triple-digit temperatures that could hit this summer.
