Industrial wastewaters can contain significant quantities of toxic pollutants and other substances.  These pollutants can interfere with the Wastewater Treatment Process.  As a result, some industries are required to provide treatment of processed water to remove any such pollutants before it can be discharged to the Wastewater Treatment Plant.  The City of Washington has implemented a Pretreatment Program in which these industries are monitored to ensure that their industrial discharges are in compliance.  Details of pretreatment are outlined in the City's Code of Ordinances.
