The San Antonio Water System had been making a homemade screen system work. It wasn’t perfect – but it only seemed to fall short in keeping grit from entering their system.
When SAWS sought to upgrade their septage collection system, they faced challenges beyond what might be normally seen in a typical WWTP.
As the SAWS team began using a demo sludge screening unit, they learned quite a bit about the solids that were coming into their receiving station. The very first truck that hooked up to the new demo unit took only minutes to clog it. Roland Gutierrez, SAWS O&M engineer, didn’t think this was possible - until he examined what had come in from several portable units around the metro area. Gutierrez found everything from knives, ammunition and power tools to clothing, syringes and electronic devices in the septage. Armed with these new details, Gutierrez reassessed the plant’s needs. By partnering with Huber Technology, SAWS was able to navigate through challenges and put together a world-class system.
