The Sandy Creek Reclaimed Water Splitter Box Project makes 15 MGD of reclaimed water available on a first priority basis to Sandy Creek Electrical Generating Station. The remainder of the reclaimed water is available to the Waco Metropolitan Area Regional Sewerage System for use in their service area. Any water not reclaimed is discharged into the Brazos River under WMARSS TPDES permit for their Central Wastewater Treatment Facility.
