San Antonio River Authority’s Martinez IV Wastewater Treatment Plant Earns Envision Silver Award

The Institute for Sustainable Infrastructure (ISI) announced today that the Martinez IV Wastewater Treatment Plant in Saint Hedwig, Texas is the recent recipient of the Envision Silver award for sustainable infrastructure.

The Martinez IV Wastewater Treatment Plant (WWTP) is a new facility built to accommodate the significant projected population growth of the surrounding communities. Without this facility, the increased raw sewage would need to be pumped and hauled by truck on a daily basis to other facilities for treatment, causing significant impacts to soil, watershed quality, air pollution, and carbon dioxide emissions.

Operated by the San Antonio River Authority (River Authority), the plant has a treatment capacity of 250,000 gallons per day (GPD) with potential to expand to two million gallons per day (MGD). The project consists of headworks, biological treatment, clarifiers, ultraviolet (UV) disinfection, and dewatering with final solids being composted. In addition, a new sanitary sewer collection line and associated lift station will connect new residential developments to the wastewater treatment plant. The collection line will consist of approximately 17,000 linear feet of gravity and force main and one lift station.

The River Authority worked in close collaboration with Freese and Nichols and MGC Contractors to deliver this award-winning sustainable project.
