Hydro` South Relief Canal Algal Turf Scrubber® 1 . INTRODUCTION Indian River County Stormwater Division is designing another regional stormwater/canal water nutrient removal facility known as PC South . It will be located contiguous to the Indian River Farms Water Control District' s South Relief Canal within Indian River County . The facility will also treat reverse osmosis concentrate from the County' s South County Reverse Osmosis Water Treatment Plant , and includes relocation of the concentrate effluent outfall to a point approximately 2 , 000 feet east of the existing outfall into the South Relief Canal Outfall . The work associated with the reverse osmosis concentrate requires an Industrial Wastewater Permit from FDEP . A 10 million gallon per day pumping facility in the South Relief Canal will be located approximately 1 . 5 miles west of PC South , The South Relief Canal is a major tributary within the network of canals managed by the Indian River Farms Water Control District ( IRFWCD ) . The proposed treatment system is to be designed around the application of an Algal Turf Scrubber® (ATSTM ) to remove nutrients from surface waters associated with the South Relief Canal ( South Canal ) and to remove nutrients and eliminate toxicity associated with the reverse osmosis concentrate . 2 . SCOPE OF WORK HydroMentia shall complete the following tasks in a timely manner , and will coordinate its efforts , and the efforts of selected subcontractors , with the Public Works Stormwater Division and Utilities Department and provide assistance in issues associated with permit procurement and engineering design for which HydroMentia is uniquely qualified .
