PISTA VIO - Municipal Headworks - Case Study

Part of a 2016 expansion project, the Elkhart Wastewater Treatment Plant improved its grit removal efficiency and wet weather capacity by installing PISTA® VIO™ Grit Chambers in existing detritor grit basins. Unlike the other technologies considered, the PISTA® VIO™ allowed utilization of existing infrastructure in addition to providing improved efficiencies and capacities.

The two 20-MGD PISTA® VIO™ Grit Chambers were installed directly inside the plant’s existing detritor-type aerated grit chamber basins. Also utilizing the existing influent/effluent channels, the system was arraigned at a 270 degree angle per the plant layout.
