Industrial Pretreatment

The Federal Water Pollution Control Act of 1972 initially defined the pretreatment program.  Section 307 of the act required the United States Environmental Protection Agency (USEPA) to develop pretreatment standards designed to prevent the discharge of pollutants from industrial users to Publicly Owned Treatment Works (POTWs) “which interfere with, pass through, or are otherwise incompatible with such works”.  The Act was amended in 1977 to require POTWs to establish a pretreatment program to ensure compliance with the pretreatment standards.

The Purpose For The City of Garland’s Industrial Pretreatment Program (IPP):

  • Protect the POTWs
  • Protect the health and safety of the workers at the POTWs
  • Protect the collection system
  • Prevent non-compliance of the EPA/TPDES permit
  • Protect the receiving waters
  • Enhance biosolids reuse and water reclamation

To accomplish these purposes, IPP inspects, and when appropriate, issues permits to and monitors industrial dischargers.  IPP is also responsible for enforcing the applicable discharge regulations.  The IPP’s ability to implement and enforce this program is determined by the City Ordinance, which gives the IPP its legal authority.

Industrial Waste Discharge Permits in Garland:

Any Significant Industrial User (SIU) proposing to begin or recommence discharging industrial wastes into the sanitary sewer (POTW) must obtain a wastewater discharge permit prior to beginning or recommencing of such discharge.  An application for this wastewater discharge permit must be filed with the City of Garland Industrial Pretreatment Program at least thirty (30) days prior to the date upon which any discharge will begin.

Significant Industrial User (SIU) is defined as:

(I)  industrial users subject to categorical pretreatment standards; and
(II) any other industrial user that:
     a. discharges an average of 25,000 gallons per day or more of process wastewater;
     b. contributes a process waste stream which makes up 5 percent or more of the average dry weather     
         hydraulic or organic capacity of the treatment plant; or,
     c. is designated as significant by the City of Garland on the basis that the industrial user has reasonable 
         potential for adversely affecting the POTWs operation or for violating any pretreatment standard or 
         requirement.

Industrial Waste Surveys:

When requested by the City of Garland, all industrial users must submit information on the nature and characteristics of their wastewater by completing a wastewater survey.
