Like most municipal wastewater service providers, the City of Mesquite’s wastewater system is designed and operated for urban, domestic wastewater. Industrial wastewater, however, may contain concentrations of metals or organics far above normal domestic wastewater. Because wastewater treatment systems are not designed to remove these contaminants, pretreatment of industrial wastewater can make wastewater safe to discharge to the sanitary sewers. Mesquite’s Industrial Pretreatment Program protects the City’s wastewater collection system, treatment facilities and environment from uncontrolled toxic pollutants. Any facility that discharges nondomestic wastewater to our sanitary sewers must meet local effluent discharge limits. This includes commercial establishments, such as restaurants and car washes, as well as manufacturers, fabricators, blenders and others.
City of Mesquite Pretreatment Program
The term "pretreatment" means the treatment of wastewater by commercial and industrial facilities to remove harmful pollutants before being discharged into the wasterwater system. The purpose for the City of Mesquite’s Industrial Pretreatment Program (IPP) is to:
• Protect the wasterwater collection system
• Protect the health and safety of the wastewater system personnel
• Protect the receiving waters and the environment
• Prevent non-compliance of the EPA/TPDES permit
• Improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges
PERMITTING & ENFORCEMENT
To accomplish these purposes, the City contracts with the North Texas Municipal Water District (NTMWD) to conduct inspections and monitor industrial dischargers. Industrial-type businesses which gererate wastewater into the collection system must obtain and maintain an industrial wastewater permit. Please contact the Pre-Treatment Coordinator at 972-216-6942 for information regarding the industrial pre-treatment program and requirements.
