The Industrial Waste (IW) Unit of Public Works regulates industrial waste discharges into over 3,000 miles of local sewers within the unincorporated areas of Los Angeles County and 36 contract cities. The Unit also regulates industrial wastewater that is collected, hauled, disposed, or discharged into the ground (where permissible).
Any business which generates, handles, or disposes of industrial wastewater must obtain an industrial waste disposal permit (Los Angeles County Code, Chapter 20.36 or contract city municipal code) from the Unit. The Unit reviews plans to determine if facilities have adequate pretreatment systems. The business must obtain clearance and an IW Disposal Permit (IWDP) for the discharge of wastewater to sanitary sewers, private disposal systems, or offsite disposal. They must comply with applicable Federal, State, local domestic and industrial waste regulations to be verified by the Unit. The Unit’s goal is to ensure that facilities are designed so as to not create a nuisance, menace the public peace, health or safety, or impact the public sewer system, soil, underground or surface waters.
If you received a referral from Building & Safety or need to obtain clearance from our office, here is useful information and common forms you will need. When you are ready to submit your package for approval, or if you have any questions, you may contact us at our public counter, via mail or phone.

Instructions for Obtaining Clearance
Industrial Waste Disposal Permits
Industrial Waste Disposal Permits (IWDPs) are subject to routine inspections and annual fees. If a violation notice is issued by one of our field inspectors, a full reply to the items requested must be submitted within the time allotted by the notice. If corrective action cannot be completed within the due date, the inspector who issued the notice must be contacted directly. Field inspectors are available for phone calls, Monday through Friday, 8 a.m. to 9:30 a.m. A listing of our field office and headquarters facilities is included in our contact page.
An IWDP is terminated when the person owning or operating the premises has filed a written request, and a field inspection has confirmed that all industrial wastewater producing operations have ceased. All pretreatment facilities must been permanently removed or closed before a permit can be canceled. If the pretreatment facilities are to be maintained for future use, a non-use permit must be obtained.
