South Florida embraces desalination and water reuse for the future
The days of limitless and cheap water in South Florida are gone. Planning, investments in alternative water sources such as desalination and reuse, and conservation are required to secure reliability and sustainability of current and future water supplies. The South Florida Water Management District (SFWMD) is the oldest and largest of the five districts in Florida. The district's mission is to oversee the water resources in the southern half of the state by balancing and improving water quality, flood control, natural systems and water supply within a 16-county region. A key initiative is restoration of the Everglades, a vast wetlands and US national park. By augmenting supplies through alternative sources - including desalination of brackish and seawater, reclaimed water and reducing demand through year-round water conservation, the SFWMD hopes to continue quenching the thirst for a renewed environment and an ever-growing population. Realizing that water desalination using reverse osmosis is energy-intensive, the district also supports studies and projects that use renewable energy to reduce the carbon footprint, operate more efficiently to reduce water use, and manage concentrate to protect the environment. To encourage diversification of water resources, public utilities that use reclaimed water for outdoor irrigation are exempt from water-shortage restrictions. This article appeared in the February/March 2009 issue of D&WR magazine.

Perth provides world desalination sustainability model
As the USA finally starts its second large SWRO plant at Carlsbad, Australia is already into a second generation, with contracts let for the Southern Seawater desalination plant, the second to serve the Perth region. The author has for many years been a strong advocate of desalination and has promoted the technology around the world. Here he argues that the Perth plant is a model of sustainability that the industry should follow. In addition, the article lists 21 existing and potential large desalination plants in Australia. The author looks at future sustainable practices and argues that they must satisfy the triple bottom-line economic, social and environmental factors. The recent cancellation of Traveston Crossing dam provides a case-study of a project that did not do this. SWRO has the ability to meet these criteria, he argues. This article was first published in the August/September issue of D&WR magazine.
