CRWS on-site stormwater storage basin more than 50 percent complete
Despite spring rains, construction crews have made substantial progress in installing ground-stabilizing anchors and pouring concrete for a 125-million-gallon stormwater storage basin at TRA’s Central Regional Wastewater System.The stormwater storage basin will help CRWS manage high influent flows during heavy rain events. The system is currently permitted to treat an average of 162.0 MGD with a peak two-hour flow of 405.0 MGD during wet weather. Flows in excess of 375.0 MGD will be routed to the basin, which is designed to hold 125 mg but has a 175 mg maximum capacity. After the storm has passed, operators will return the stored effluent to the treatment process.
CRWS treats wastewater for 20 DFW Metroplex cities and the Dallas/Fort Worth International Airport. The CRWS plant and collection system are undergoing construction to improve processes and expand treatment and transportation capacity to 189.0 MGD with a peak two-hour flow of 623.0 MGD.
