The City of Los Angeles is required, by mandate, to protect the health and safety of the public while ensuring that the wastewater collection systems and treatment plants are not unduly impacted by discharges from industrial users.
An industrial user is a discharger of any water bearing waste other than domestic wastewater or of wastewater generated from household type operations performed at commercial establishments for or to support commercial purposes.
Businesses that are industrial users are generally required to obtain an Industrial Wastewater Permit.
Existing and new businesses in the City of Los Angeles are required to review the requirements set forth in the Industrial Waste Control Ordinance as specified in Section 64.30 of the Los Angeles Municipal Code and determine if they are required to comply with the ordinance. Examples of businesses that are required to apply for an industrial wastewater discharge permit are (but not limited to) metal finishing and plating shops, car washes, food service establishments, (restaurants, supermarkets, bakeries, etc.) laundries and printed circuit board manufacturers.
Please contact Industrial Waste Management Division (contact information can be found at the bottom of this page) if you have questions or are not sure if you are required to apply for a permit.
