JOHN'S RIVER WATER NUkNAGENIENT DISTRICT ALTERNATI vT <br />WATER SUPPLY GRANT APPLICATION FOR ELIMINATION OF REVERSE <br />OSMOSIS CONCENTRATE INTO THE INDL4N RIVER LAGOON <br />BACKGROUND <br />Reverse Osmosis (R -O.) Treatment Facilities cleanse water by separating dissolved minerals and other <br />undesirable particles from the deep ground (Floridan Aquifer) water through the use of filtering membranes. <br />The reject water, or "concentrate" is then discharged as non -Publicly -Owned -Treatment -Works (POTW) <br />industrial wastewater into the Indian River Lagoon. The Department of Environmental Protection (DEP) has <br />put increasing pressure on permittees of R -O Treatment Facilities to eliminate concentrate discharge into the <br />Lagoon, which is classified as an Outstanding Florida Water (OFW). Presently, the Department of Utility <br />Services has two RO, facilities with concentrate; discharges into the Lagoon, one directly into the OFW. Oil <br />December 7, 1999 the Board of County Commissioners authorized the County's water treatment continuing <br />services consultant Camp Dresser and McKee, Inc. (CDM) to develop alternatives for disposal of R -O. <br />concentrate. The report was presented to the County's Utility Advisory Committee on June I", 2000 and has <br />since been finalized (see attached excerpts). <br />Each year St. Johns River Water Management District (SJRWMD) allocates funds appropriated by die federal <br />government to assist public and private entities to develop ways of providing alternative water supplies for <br />various uses. In 1997 and 1993, Indian River County was successful in obtaining $75,000.00 and <br />$100,000.00, respectively, to help fund construction of the North County R.0 Facility (NCRO). This year <br />SJRWMD has $750,000.00 available for funding alternative water sources throughout their district. <br />DECEMBER 4,2001 <br />L;A , ,-)6 77 <br />-114- <br />
