Industrial facilities and certain commercial facilities, which plan to discharge industrial waste to the City's sanitary sewer system may be required to obtain an Industrial Waste Permit. For our purposes, Industrial Waste is defined as:
"Any waterborne solid, liquid or gaseous waste, resulting from any production, industrial, manufacturing or food processing operation or from the development, recovery or processing of any natural resource, including waste that is required to be pretreated by Chapter 47, Section V or the City's Plumbing Code."
Industrial waste also includes wastes subject to specific categorical pretreatment standards at 40 CFR Parts 405-471 or regulated by 40 CFR Part 403.
If you are a facility wanting to discharge non-domestic wastewater into the sanitary sewer system, please contact the Industrial Wastewater Service at (832) 395-5800 or [email protected] to discuss your firm's operations, complete and submit an Industrial Waste Survey form. The Industrial Wastewater Service (IWS) will then review and follow-up with the next steps (e.g., an onsite inspection needs to be performed, a permit application needs to be submitted, a permit is not required, etc.). If the form is deficient, the customer will have to make appropriate corrections before moving to the next step.
You do not need an Industrial Waste Permit if your business is:
- a self-service or commercial (i.e., not industrial) laundry,
- a restaurant
- a car wash.
Additionally, the City of Houston is not currently requiring an Industrial Waste Permit for the following operations: hospitals, analytical and research laboratories, small photographic developing operations and printers. Such facilities still need to complete and submit the Industrial Waste Survey Form.
However, any facility discharging industrial waste to the sanitary sewer system may be required to obtain an Industrial Waste Permit if the Industrial Wastewater Service makes that determination.
