Wastewater
The Wastewater Treatment Plant was established in 1936. To date, it has gone through several updates to facilitate the growing population and businesses. Currently the design flow is 5.0 MGD (million gallons daily). The peak flow capacity is 12.5MGD. The primary treatment is to remove grease, grit, and to screen out debris. Our secondary treatment is done with aeration to remove phosphorus and ammonia. From April 1st to October 31st we disinfect with sodium hypochlorite (Bleach) to remove ecoli. The water is then treated with sodium bisulfite to de-cholorinate before being discharged to the Elkhart River.
During rain events, the plant can reach its 12.5MGD, Before 2011 there were many CSO (Combined Sewer Overflow) sites throughout Goshen that would dump the excess into the Elkhart River. Since 2011, Goshen has built a Wet Weather Detention Facility to capture the extra water from rain events. To learn more about CSOs, please click here.

NEW: Pollutant Minimization Program Plan (PMPP)
The wastewater treatment plant has a SCADA (supervisory control and data acquisition) system. The SCADA system controls and monitors the plant 24 hours a day, 365 days a year. The SCADA system also has alarming capabilities that send alarms to the correct people to notify them if something is wrong with either of the plants as well as any of the 38 lift stations.
