Well pumping is commonly used to move material away from its source. The most common forms of well pumping in WRRFs are pump stations, either within the collection system or within the facility, that are used to move wastewater to a higher elevation. Well pumping can also occur at several locations within a WRRF to move material such as waste sludge, facility drainage, groundwater, basins, or other areas where fluid flows into a well to be pumped. The main purpose of well pumping is to remove material from the source (well). Therefore, the well level is typically the process variable used for control of these systems.
