Pretreatment Program

Obtaining a Discharge Permit​

Permit To Discharge Industrial Wastes

A permit is required for industries in Dallas discharging industrial wastes to the wastewater collection and treatment system. The process for obtaining a discharge permit and the type of pollutants monitored vary depending on industrial processes and categories. One provision of the approved Pretreatment Program is the requirement that all significant industrial users of the wastewater system obtain and maintain a Wastewater Discharge Permit. 

Groundwater Discharge Permit and One-time Discharge

A groundwater discharge permit is required for remediated groundwater discharges to the City sanitary sewer system. Permits are issued for groundwater remediation projects which discharge to the sanitary sewer over a period of time.
