(Do not refer to attachments . ) <br /> Increase amount of reclaimed water by supplementing with R.0. concentrate <br /> 3. Brief description of project. Include approximate dimensions and capacities . (Do not refer to <br /> attachments . ) <br /> Reverse Osmosis (R . O . ) water treatment process involves micron level filtration that generates a waste <br /> stream by-product referred to as concentrate Currently concentrate is discharged to the Indian River <br /> Lagoon where it is commingled with the waters of the intra coastal waterway and disposed This project <br /> will provide for the concentrate (initially 750 000 gallons per day and ultimately 1 5 mgd) to be rerouted <br /> to the Bent Pine Rapid Infiltration Basin (RIB) site At that point the concentrate will be discharged into <br /> the RIB basin and mixed with stormwater withdrawn from the Indian River Farms North Relief Canal . <br /> The stormwater/concentrate mixture will be routed through the RIB basin to allow sedimentation of solids <br /> and nutrient removal from wetland plants A portion of the mixture will be withdrawn from the RIB site <br /> and supplied to golf courses for irrigation The remainder will be discharged into the Lateral G Canal <br /> Approximately four miles of 16" PVC water main will be constructed from the North County R O Plant <br /> south along 58`h Avenue to the 570' Street right-of-wav and along the 57`h Street right-of way to the RIB <br /> basin. A control structure will be constructed west of the Lateral G Canal . A pumping station will be <br /> constructed upstream of the control structure for routing stormwater/concentrate through the reclaimed <br /> water system and the manmade wetlands system A 32 acre wetlands system will be developed <br /> downstream of the pump system within the RIB site Another pump system will be developed <br /> downstream of the wetlands for routing treated effluent through the reclaimed water system or <br /> discharging excess into the Lateral G Canal <br /> EVALUATION FACTOR related to questions 11-2 and 11-3. <br /> Will the project implement new or innovative procedures or technology which can serve as a demonstration, <br /> pilot project, or source of useful data for water resource management? 140 points . Based on rater 's <br /> assessment of the degree of innovation being proposed or the utility of data generated by the project, with <br /> greater innovation or use of data getting more points. <br /> 4. Project location (address or description) . <br /> The County' s North Regional R O Water Treatment Facility is located at the norhwest corner of 58Th <br /> Ave . and 77Th St. The onsite concentrate/stormwater recovery and manmade wetlands facility shall be <br /> located at the northwest Corner of the North Relief Canal and the Lateral G Canal (present location of the <br /> County' s Wastewater RIB site) <br /> County (ies) in which project is located : Indian River <br /> Page A - 3 <br /> FAXJti1tin\U7XrrY - ENGINFERING\Prga4 - Utility Construction Pwmib\StC - 2003 SIR WDm Altsom" Wuhu Supply Gnn Appt3t John ARurumd" Wuta Supply Applioutiou­Brin to North <br />Rdiuf CawL&c <br />
