Project Spotlights:
• Under contract with MBD Consulting Engineers, P.A., WEC provided NPDES permit and outfall design support for a proposed WWTP upgrade.
• Services included field measurements for bathymetry, current velocity, and temperature as well as multiple CORMIX modeling scenarios for various outfall configurations. The project resulted in whole effluent toxicity (WET) limitations with sufficient compliance margin for the plant expansion and addressed NPDES permit limits for future expansion plans.
• Saluda County Water and Sewer Authority proposed a new, larger WWTP but was unable to acquire a new wasteload allocation at the existing site discharge due to existing dissolved oxygen impairments within the Little Saluda River.
• Under contract with MDB Consulting Engineers, P.A, WEC completed field measurements and water quality modeling of the proposed discharge to demonstrate the project’s compliance with state water standards, potentially saving millions in project capital costs.
• Under contract with MDB Consulting Engineers, P.A, WEC completed field measurements and water quality modeling of the proposed discharge to demonstrate the project’s compliance with state water standards, potentially saving millions in project capital costs.
• WEC was subcontracted by MBD Engineering Consultants to perform CORMIX modeling to design a single-port diffuser that provides rapid mixing for meeting whole effluent toxicity (WET) limits and enhances instream uses.
• WEC provided regulatory compliance support for Santee Cooper by evaluating low and average annual instream flow rates used by the SC Department of Health and Environmental Control (SCDHEC) to establish permit limits.
• WEC used the CORMIX model and revised flow to establish whole effluent toxicity limits and recommendation for a multiport diffuser system to improve mixing.
