Sulphur Springs WWTP Improvements

Process rehabilitation to improve treatment efficiency

Garver provided design services for Sulphur Springs’ wastewater treatment plant improvements project. The design involved improving the plant’s treatment capacity approximately 45% within the 5.4 MGD facility’s existing footprint. We prepared a phased approach that would allow current upgrades to increase capacity within the existing aeration basins while preparing the plant for future biological nutrient removal implementation and solids improvements in a future project. A significant component of the design involved a construction phasing plan that allowed the facility to stay online while constructing the improvements within the existing basins and existing footprint. Garver’s biological modeling developed cost-efficient schemes that reused existing facilities to achieve the immediate nitrification goals, which maintained the City of Sulphur Springs, Texas’ budget while delivering process flexibilities and control to serve the City well in meeting future permit limits.

Following selection for design and construction services, Garver began coordination with the Texas Water Development Board (TWDB) to provide design and construction services in compliance with the Clean Water State Revolving Fund (CWSRF). The project provided conversion to diffused aeration, new aeration basins, new secondary clarifiers, and new pumping facilities. Throughout the project, Garver assisted the City in maintaining compliance through regular submittals to the TWDB, incorporating procurement requirements into the construction contract, and providing full-time inspection services.
