News Beat The Association of Metropolitan Water Agencies (AMWA) honored the Miami-Dade Water and Sewer Department (WASD) with its top utility management award on Oct. 12, 2015, at last year’s Executive Management Conference in Savannah, Ga. The Sustainable Water Utility Management Award recognizes water utilities that have made a commitment to management that achieves a balance of innovative and successful efforts in areas of economic, social, and environmental endeavors. Recognized for its water use efficiency program, WASD improves management of traditional water supplies, encourages development of alternative water supplies, and improves water use efficiency. The Department has an aggressive supply-side management water loss reduction program, including improvements in the distribution system, a vigorous leak detection program, and advanced meter infrastructure. Its methane sequestration project increases self-generated electricity for use at wastewater treatment plants. An asset management system minimizes the total life cycle cost of its capital assets, and the capital improvement plan provides long-term funding to complete upgrades. The WASD employee recognition program has produced more than $38 million in savings. “We are committed to sustainability and environmental protection, and public education and outreach programs are key compo-
nents in our success,” said WASD director Lester Sola. “It’s an honor to be recognized for the work we do in the department and its positive impacts on the environment.” The City of Clearwater has finished the design, construction, and permitting for its new $30 million brackish, reverse osmosis (RO) water treatment facility (WTF). The new facility is the first large-scale RO municipal system in Florida to use ozone to treat hydrogen sulfide in RO permeate. Prior to completion of the new facility, the city used water from the Florida aquifer and purchased water in bulk from a regional supplier to meet its customer needs. In an effort to manager the cost of water, protect the environment, and conserve water resources, the city implemented an integrated water management strategy. One of the priorities for the city was to expand its existing potable water system, including an upgrade of the existing WTF to the brackish water RO facility. The new facility was funded in part by the Southwest Florida Water Management District in Tampa. The facility exceeds federal and state standards and will serve 100,000 customers.
The South Florida Water Management District (SFWMD) has approved a water supply plan for Central Florida that charts a longterm course of more aggressive water
conservation, expanded and more efficient water reuse projects, and alternative water supply project options to ensure adequate water supplies for the region through 2035. The plan was developed as part of the Central Florida Water Initiative (CFWI), which includes Orange, Osceola, Polk, Seminole, and south Lake counties. “This is an important step forward to meet the long-term water supply needs of residents, businesses, and agriculture in Central Florida,” said Daniel O’Keefe, SFWMD governing board chair. “With input from an array of stakeholders, the plan represents a combination of strategies to effectively address the challenges of protecting water resources for the region.” Water supply plans identify future water supply needs for a 20-year planning horizon, and the programs and projects needed to ensure sustainable supplies; however, the plans do not require that specific projects be implemented. Decisions to choose project options are made at the local level by water supply utilities. The CFWI is a collaborative effort that engages three water management districts, the Florida Department of Environmental Protection, the Florida Department of Agriculture and Consumer Services, central Florida utilities, and stakeholders representing agriContinued on page 46
