Explain the purpose(s) of the project. (Do not refer to attachments . ) <br /> Increase amount of reclaimed water by supplementing with R O concentrate and stormwater mixture <br /> 3. Brief description of project. Include approximate dimensions and capacities . <br /> (Do not refer to attachments.) <br /> Reverse Osmosis (R. O . ) water treatment process involves micron level filtration that generates a waste <br /> stream by <br /> :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 <br /> pr�ect will provide for the concentrate (initially 750,000 gallons per day and ultimately 2 25 mgd) to be <br /> rerouted to the Bent Pine Rapid Infiltration Basin (RIB ) site At that point the concentrate will be <br /> discharged into the RIB basin and mixed with stormwater withdrawn from the Indian River Fauns <br /> North Relief Canal. The stormwater/concentrate mixture will be routed through the RIB basin to allow <br /> sedimentation of solids and nutrient removal from wetland plants A portion of the mixture will be <br /> withdrawn from the R11B site and supplied to golf courses for irrigation The remainder will be <br /> discharged into the Lateral G Canal Approximately four miles of 16 " PVC water main has been <br /> constructed from the North County R O Plant south along 58th Avenue to the 57th Street <br /> right-of--way to the RIB basin during Phase 1 of this Project The second phase will involve <br /> constructing a pumping station on the west side of the RIB site for mixing stormwater with <br /> concentrate and routing through the reclaimed water system and the manmade wetlands system A <br /> 32 acre wetlands system will be developed downstream of the pump system within the RIB site <br /> Another pump system will be developed downstream of the wetlands for routing treated effluent <br /> through the reclaimed water system or discharging excess into the North Relief Canal <br /> A-3 <br />
