Industrial Pretreatment Program

The Environmental Services Division of Engineering administers the EPA-approved Industrial Pretreatment Program. The Program was awarded the EPA Clean Water Act Pretreatment Program Excellence Award for 2001. The purpose of the Program is to protect the sewer collection system, the wastewater treatment plants, public safety, and the environment. The Industrial Pretreatment Program is mandated by the USEPA for cities whose combined wastewater treatment capacity for all wastewater plants exceeds 5.0 million gallons per day (MGD) or receives discharge from any federally-regulated (Categorical) manufacturing process. Texarkana Water Utilities operates three wastewater treatment plants with a combined design capacity of 20.95 MGD and receives regulated discharges from five (5) Categorical Users. Program requirements are outlined in the Code of Ordinances (Texarkana, TX / Texarkana, AR) and apply to all Nondomestic (nonresidential) Users of the sanitary sewer system.

Identification and survey of new Nondomestic Users is continuous by means of the Request for Nondomestic Connection available through the link or from a Customer Service representative. Any person wishing to establish nonresidential water or sewer service is required to complete the Request and return the original to Customer Service when applying for water or sewer service. Facsimile and photo copies of signatures are not acceptable.

Environmental Services regulates Nondomestic Users through wastewater discharge permits. All facilities whose processes are Federally regulated or who discharges more than 25,000 gallons of process wastewater per day (defined as "Significant Users") are required to obtain a Permit prior to commencement of discharge to the sanitary sewer system. The User is required to file an Application for Wastewater Discharge Permit at least 90 days prior to anticipated date of initial discharge. Other Users may be required to obtain a Permit. Whether a permit is required and what type of permit is required is dependent upon the processes employed at the facility, the type of wastewater discharged and/or the amount of wastewater discharged. Contact Environmental Services for more information.

  1. All Significant Users are required to maintain a Wastewater Discharge Permit. A significant User is defined as one who is regulated by Federal Standards (Categorical Users) or one who discharges 25,000 gallons or more of process wastewater per day. The Program currently regulates ten (10) Significant Users.
  2. All Transporters of liquid nonhazardous waste who wish to discharge to the wastewater treatment plant are required to maintain a Wastewater Discharge Permit.
  3. Other nondomestic Users who discharge pollutants of concern may be required to obtain a Permit.
  4. Facilities who employ a Federally-regulated process but do not discharge from the process may be required to obtain a No-Discharge Permit.
