To support permitting of a discharge of treated wastewater effluent from a new wastewater treatment plant, Plummer developed a QUAL-TX model from HEC-RAS cross-sections of the receiving stream. Plummer customized site-specific model hydraulic coefficients for the stream by fitting curves to the velocity-flowrate and depth-flowrate relationships obtained from the HEC-RAS model. Plummer used the model to identify discharge flowrates and effluent quality limits that are projected to maintain the Texas Surface Water Quality Standards in the receiving water. Plummer wrote a modeling technical memorandum that was submitted as part of the TPDES permit application, answered TCEQ questions about the model, and assisted the client in gaining approval of the model from TCEQ modeling staff.
