MSSC 2011 Annual Salinity Summit February 17 18, 2011 Thirty Years of Success in Implementing Desalination By Roger K. Noack, P.E. HDR Engineering, Inc. Presentation Overview History of Desalination in Florida - In the Beginning - Overtime there have been some speed bumps - Where we are today Summary In the Beginning Rotunda West Utilities - Placida, Florida Brackish RO Plant MGD Design Capacity - Groundwater source high TDS and chlorides - Surface discharge for the concentrate Permitting Permit to Construct Permit to Operate Local permits building, clearing, environmental, etc. Permit to Discharge the Concentrate - Started design before having the permit - Application is a couple of pages - Received approval in a couple of months Minimal public input As the world turns. More desal plants constructed More information becomes available More public involvement More headaches More engineering work As the World turns. Mid 1980s Most sources are groundwater Discharge to ocean Major-Seawater Ion Toxicity Toxicity resulting solely as a result of a surplus or deficit of one or more of the major seawater ions or from the relative proportions of those ions. As the World turns. Tampa Bay Desalination Plant West Coast Regional Water Supply Authority ordered to reduce groundwater use 23% by In October 1996, West Coast Regional Water Supply Authority issued RFP for commercial developer to design, build, operate, and own a desalination plant. - March plant finally hits goal of 25 MGD for 4 months and 20 MGD for 12 months Where are we today Over 140 desalination plants Capacity totaling over 500 MGD Ranging from 0.01 to 25 MGD Source - Ocean A couple - Surface 1 plant - Groundwater Overwhelming majority Concentrate Disposal in Florida Permitting Today Permit to Construct Permit to Operate Local permits building, clearing, etc. Permit to Discharge Demineralization Concentrate Recommend getting Discharge Permit before proceeding with design Permit to Discharge Demineralization Concentrate 10 pages of instructions 20 page form Discharge determines information required - Surface - Underground injection - Land application - Blending with reclaim water - Blending at wastewater facility All information available to public Summary Florida has led the way in desalination The path has not been easy First DBOO industry learned a lot from this experience More open process today than in the past Can get a permit for construction, operation and discharge, but it will take some time 1 to 2 years MSSC 2011 Annual Salinity Summit February 17 18, 2011 QUESTIONS COMMENTS Contact:
