INDIAN RIVER COUNTY, FLORIDA <br />DEPARTMENT OF UTILITY SERVICES <br />Date: March 18, 2019 <br />To: Jason E. Brown, County Administrator <br />From: Vincent Burke, P.E., Director of Utility Services <br />Subject: 286 +/- acre Purchase and Sale Agreement <br />DESCRIPTIONS AND CONDITIONS: <br />The West Regional Wastewater Treatment Facility (WRWWTF) is currently operating under Florida <br />Department of Environmental Protection (FDEP) permit FL0041637. The existing plant is currently rated <br />at 6.0 million gallons per day (MGD) annual average daily flow (AADF) permitted capacity. Adjacent to the <br />WRWWTF is an existing 4.0 MGD AADF discharge from the plant to the created wetland. The Wetland <br />Treatment System (WTS) is sized at 169 acres +/- with wetted area totaling approximately 135 +/- acres <br />consisting of one deep settling pond, nine deep marsh flow through cells and three shallow marsh cells <br />with a final storage outfall cell at the southwest corner of the site into the Lateral D canal near 1-95. Under <br />routine operating conditions, the Indian River County Department of Utility Services (IRCDUS) receives <br />and treats the domestic wastewater using advanced treatment capabilities in order to separate the solids <br />and further process the liquids and to then create reclaimed or reuse water. For most of the year, IRCDUS <br />supplies multiple golf course locations this irrigation quality reuse water in lieu of those locations using <br />groundwater. <br />During times of heavy influent flows or when there is unusually high precipitation, the WRWWTF must <br />still treat the wastes it receives and send the reclaimed water out to the system. As receiving ponds fill <br />up, the only option is for the reclaimed water to be sent to the WTS where additional biological treatment <br />occurs. When that scenario occurs, there is a possibility for permitted discharge to the Lateral D canal to <br />start. During those intermittent discharges, the FDEP permit requires that certain parameters must be <br />met for water quality and quantity, and that nutrient levels must be tracked. The current WRWWTF FDEP <br />permit is issued under the federal program for the Environmental Protection Agency's (EPA) National <br />Point -Source Discharge Elimination System (NPDES). The Total Maximum Daily Load (TMDL) for the <br />facility, in concert with the Basin Action Management Plan (EMAP) for this area, is structured in order to <br />comply with the EPA's mandate and has very restrictive Waste Load Allocations (WLA) tied to the <br />WRWWTF for Total Nitrogen (TN) and Total Phosphorus (TP). The FDEP permit and associated WLAs <br />restrict the way IRCDUS is able to operate the WTS in attempting to stay at or below the WLA. Thus, <br />IRCDUS is seeking alternative wet weather reclaimed water storage/disposal options for the WRWWTF. <br />This need is especially critical since the County has been experiencing tremendous growth as well. IRCDUS <br />has processed an average of 125 new meter installs each month for the past 18 months, and this growth <br />Page 1 of 5 <br />C:\G ra nicus\Legista r5\L5\Temp\614baa 68-ed37-49d2-b48c-97d5d6a5626c.docx <br />
