The Department of Utility Services is exploring one of the alternatives outlined in CDM's report; mixing a portion of the concentrate with storm water/reclauned water. The Department of Utility Services is requesting the Board Of County Commissioners to authorize applying for the grant, with a commitment of matching funds to implement the project ANALYSIS The attached grant application will be submitted to SJRWMD for a project to supplement reclaimed water with a mixture of stormwater and concentrate for irrigation purposes The concentrate discharge from the R.O. process will be routed to the North Relief Canal along 58'h Avenue Concentrate will be discharged into the North Relief Canal and allowed to mix with stormwater and flow to the intersection of the Lateral G Canal. At that point a control structure will be constructed to retain the stormwater/concentrate mixture for recovery and reuse as irrigation. Project costs are estimated as follows Stormwater Mixmv with Brine 137500 L.F. 16" Brine Line Control Structure E/0 Lateral G Canal Pumping Station at Wetlands Headworks Wetlands Construction ' Pumping Station at Wetlands Tailworks Lateral G Overflow Structure Construction Subtotal 15% contingency Construction Total Engineering Permitting and Inspection (14.690 Construction Subtotal) Total Project Cost $9207000.00 $7207000.00 $26500.00 $2657000.00 $265700000 $265.000 00 $2,7001000 00 $405,00000 $35105,000.00 $395,000.00 $3,5007000.00 The total project cost as outlined above is $3,500,000.00 The County will request a $150,000 00 (4.29%) grant. The County's total share will be funded from the capacity charge fund, Account Number 472-000-169- 392.00. RECOMMENDATION The staff of the Department of utility Services recommends that the Board of County Commissioners approve the grant application, authorize matching funding of construction of the projects outlined above (upon receipt of grant), and authorize the Chairman to execute applications and agreements associated with grant, as presented. Commissioner Adams questioned the balance in the capacity charge fund, and Utilities Department Director Erik Olson stated that he would check and let her know. Commissioner Adams remarked that this is a 3.5 million dollar project with only $150,000 coming back in grants from SJRWMD. Director Olson hoped that this is the first of what staff believes to be a number of grants. This one became available very quickly but the intent is to take advantage of grants through the Legislature and St. Johns River Water Management District. DECEMBER 4, 2001DWI%g `w t -115-
