Water at Work - Installing New Injectors

By Lindsay Wochnick


During the groundwater off season, Operating Engineers Eric and Jasmine (not shown in photo) removed the old PVC injectors and installed new stainless retractable injectors.

During the 2015 groundwater augmentation run, one of the hypochlorite injectors used to treat the Well Field water before entering our distribution system unexpectedly failed. This caused a temporary shutdown of the chemical injection in order to make an emergency repair.

To ensure the groundwater system would not be affected by a future injector malfunction, stainless retractable injectors were installed. These new injectors are designed to be removed from the pipe without having to shut down the groundwater system. This is one of the many system improvements that have been made since the last groundwater run.

Special thanks to Groundwater Operating Engineers Eric and Jasmine for preparing the Groundwater Pump Station for the next run!
