Control and Monitor Solution for Food Processing Facility’s Gray Wastewater Discharge

The Client: Food Processing Facility


The food processing facility client needed a way to monitor and control gray wastewater discharge created from wash down activities conducted in the processing area. The EPA allowed the client to discharge a certain number of gallons on an hourly basis. The client was allowed to discharge the wastewater in a natural drainage system that eventually arrived at a small creek. The hourly amount was variable and dictated by the small creek level.


LEC created a system that controlled a 6” valve and monitored water flow over certain time periods while continuously monitoring the creek level. We then created the calculations that matched the EPA requirements. We also created a report that the client collected every 24 hours to verify the discharge amount remained within the EPA guidelines
