Industrial Pretreatment


The Town of Davie Utilities Department administers an Industrial Pretreatment Program as part of a collaborative effort of federal, state, and local regulatory environmental agencies whose shared objective is to protect water quality. 

Pretreatment is the removal, reduction, or alteration of pollutants in industrial or non-domestic wastewater prior to discharge or introduction into Publicly Owned Treatment Works (POTW, i.e., Town’s sewer collections system and wastewater and reclaimed water treatment plants). The program is designed to reduce the level of pollutants discharged by industries and other non-domestic wastewater sources into POTW, and thereby reduce the amount of pollutants released into the environment through wastewater. 
The major objectives of the Industrial Pretreatment Program are:
• To prevent the introduction of pollutants into the POTW that will cause interference with its operation;
• To prevent the introduction of pollutants into the POTW that will pass through the POTW, inadequately treated, into receiving waters of the State;
• To protect the health and welfare of the general public and POTW personnel;
• To promote opportunities for the beneficial reuse and recycling of wastewater, reclaimed water, residuals, and sludges.

These objectives are accomplished through permitting and compliance activities at the local, state, and federal levels. Individual industrial facilities are regulated by the Town of Davie Utilities Department (also known as the control authority), under its Town’s Sewer Ordinance and per State of Florida Administrative Code 62-625.400.

The Town issues Industrial Discharge User Permits to many industrial facilities discharging to the sewer system. The enforceable Industrial Discharge User Permits typically require self-monitoring of industrial process effluent quality and routine reporting. In addition to the self-monitoring and reporting, the Town’s Industrial Pretreatment conducts monitoring activities to ensure the reliability of the self-monitoring process. All permitted industrial facilities are inspected at least annually by the Town. The Town Industrial Pretreatment Program ensures that all industrial users comply with local, state and federal regulations.

If you have any questions regarding the program, please contact the Town of Davie Utilities Department at (954)-327-3742 during normal business hours.

ONE-TIME COMPLIANCE REPORT FOR DENTAL DISCHARGERS REGULATED UNDER 40 CFR Part 441

The United States Environmental Protection Agency (EPA) has promulgated pretreatment standards to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs). The reason for this is to prevent mercury from entering and contaminating our water supplies. The Dental Office Category regulation is codified in 40 CFR Part 441. Dental offices that place or remove amalgam must operate and maintain an amalgam separator and must not discharge scrap amalgam or use certain kinds of line cleaners. The effective date of the rule is July 14, 2017. For more information on the “Dental Amalgam Rule”, please see EPA’s website: https://www.epa.gov/eg/dental-effluent-guidelines 

Instructions: The following is a form that contains the minimum information dental facilities must submit in a one-time compliance report as required by the Effluent Limitations Guidelines and Standards for the Dental Office Category (“Dental Amalgam Rule”). If you are a Dental office/facility, the Town of Davie Utilities requests your full cooperation in completing and submitting this form promptly. Click HERE for the form.
