Industrial Pretreatment

The Industrial Pretreatment Program (IPP) is a federally mandated pollution control program under the Clean Water Act which regulates the discharges of industrial and commercial facilities to the sanitary sewer system. The Industrial Pretreatment Section (IPS) oversees the Mesa Pretreatment Program. 

IPS Goals:

• Prevent the introduction of pollutants into wastewater treatment plants that will interfere with treatment operations.
• Prevent the introduction of pollutants that will pass through the treatment works and be incompatible with the environment.
• Improve the feasibility of recycling and reclaiming the municipal and industrial wastewaters and biosolids.
• Enforce applicable U.S. Environmental Protection Agency (EPA) wastewater quality standards.
• Reduce the health and environmental risk of pollution caused by wastewater discharges to wastewater treatment plants.

Pollution Prevention

We have numerous resources available to any business seeking to prevent the discharge of pollutants to the environment. In some instances, the implementation of pollution prevention strategies can keep a business from receiving a permit.

Education Opportunities

Let us know if you would like a representative of IPS to speak with your school or group about the pretreatment program.
