Pretreatment Program

The City of Round Rock Pretreatment Program administers local, state and federal regulations to control pollutants discharged from commercial and industrial users within the City, which may interfere with the City’s Publicly Owned Treatment Works (POTW).  The Pretreatment Program regulates non-domestic discharge to the Brushy Creek Regional Wastewater System (BCRWWS) sewage collection and treatment facilities.  It protects the treatment process and keeps costs down by working with local businesses to minimize pollutant discharge.

Regulation of such discharges is necessary to achieve the following objectives:

  • Prevent interference with the operation of the facilities
  • Prevent pass-through of the treatment facilities
  • Prevent any other condition which would be incompatible with the facilities
  • Ensure the quality of sludge to allow its use and disposal in compliance with statutes and regulations
  • Improve the opportunity to recycle and reclaim wastewater and sludge
  • Provide for equitable distribution of the cost of operation, maintenance and improvement of the POTW
  • Enable the POTW to comply with Texas Pollutant Discharge Elimination System (TPDES) permit conditions, sludge use and disposal requirements and any other federal or state laws

The City of Round Rock Pretreatment Program is defined in the Code of Ordinances Chapter 44, Article IV.

Industrial User Survey

The City of Round Rock Pretreatment Program is required to routinely collect information from non-domestic dischargers to help the City evaluate the nature of wastewater from each business to determine whether a wastewater discharge permit is required.  Commercial and industrial users within the City are asked to complete the Industrial User (IU) Survey.

After the IU Survey is submitted to the City, the City will review it and determine if a wastewater discharge permit is necessary.

Who needs a waste water discharge permit?

All Significant Industrial Users (SIU) are required to obtain a wastewater discharge permit prior to discharging process waste water into the sanitary sewer system.  An SIU is defined as a facility that meets any of the following criteria:

  • A categorical industrial user (CIU) facility subject to national categorical pretreatment standards
  • A facility that discharges an average of twenty-five thousand (25,000) gallons per day (gpd) or more of process flow to the POTW
  • A facility that contributes a process flow which makes up five (5) percent or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant, or
  • Any other facility that the City believes has a reasonable potential for adversely affecting the sewer system and the POTW treatment plant

Additionally, any other business, individual or entity connected to the sanitary sewer, which, in the opinion of the City, requires a permit, is also required to obtain a wastewater discharge permit.

How is a wastewater discharge permit obtained?

Follow the instructions outlined in the Permit Application Instructions to complete the City of Round Rock Application for Sewage Discharge Permit.

New users must submit an application for a Sewage Discharge Permit according to the following schedule:

  • New SIU:  Application shall be submitted at least 180 days prior to commencing discharge of process wastewater.
  • Other new users:  Application shall be submitted at least 90 days prior to commencing discharge of process wastewater.

Permitting Process

  1. The user will submit the completed application to the City along with the Authorized Representative Designation Form.
  2. The City will review the documents and determine if a permit is necessary.
  3. If a permit is necessary, the City will develop a draft permit and fact sheet for the user to review and make comments.
  4. If the new user is determined by the City to be a Categorical Industrial User (CIU), then a Baseline Monitoring Report (BMR) form is required to be submitted at least 90 days prior to commencement of discharge from the facility.  Follow the instructions outlined in the Instructions for Completing the Baseline Monitoring Report to complete the City of Round Rock Baseline Monitoring Report.
  5. The City will issue a final permit.
  6. If the new user was determined by the City to be a categorical industrial user (CIU), then a 90-Day Report on Compliance with Categorical Pretreatment Standards form is required to be submitted within 90 days following commencement of discharge from the facility.  Follow the instructions outlined in the Instructions for Completing the 90 Day Compliance Report with Categorical Standards to complete the City of Round Rock 90 Day Compliance Report.
