Industrial Pretreatment Program

Why is a Pretreatment Program Needed?
 
The purpose of having a local pretreatment program connected to a wastewater treatment facility is to effectively implement the Federal and State pretreatment standards at the local level. This prevents interference with the operation of the BRWA's treatment facilities, prevents pass-through of pollutants in the treatment facilities to the waterways, protects wastewater treatment facility workers, protects facility equipment/collection system infrastructure, and prevents the contamination of the facility’s biosolids.

It is helpful to group industrial users according to a classification scheme. This scheme often includes such factors as the type of industry, flow rate, and the character of their waste discharge. The scheme that the BRWA uses is:
​​


Group #1:

Major, or Significant Industrial Users, are defined as those that meet any of the following criteria:

  • Are subject to categorical standards

  • Discharge a nondomestic waste stream of 25,000 gallons (0.025 mgd) or more per day.

  • Contribute 5% or more of the average dry weather hydraulic or organic capacity of the WWTP.

  • Have a reasonable potential, in the opinion of the WWTP supervisor, to adversely affect the treatment plant (inhibition,
    pass-through, sludge contamination,
    or endangerment of personnel). 
These industries are regulated individually by a discharge permit and have specific effluent limits placed upon their discharges. They are also monitored and inspected periodically to ensure compliance.



Group #2:

Major Non-Significant Industrial Users and Commercial Users, are defined as those that meet any of the following criteria:

  • Are small industries and/or commercial users (auto repair shops, car washes, laundromats, etc.) whose discharges do not significantly impact the treatment system.

  • Discharge a nondomestic wastestream < 25,000 gpd.

  • Contribute < 5 % of the average dry weather hydraulic or organic capacity of the WWTP.
Industries that have the potential to discharge a nondomestic or process waste stream, but currently only discharge a sanitary waste stream may also be included in this grouping.

Industries in this group may be included in a general permit system and occasionally monitored and inspected to determine if their status has changed.



Group #3:

Insignificant Industrial Users are defined as those that:

  • ​Have been eliminated from further consideration. They do not discharge to the collection system or else do not have any reasonable chance to discharge non-domestic waste stream to the POTW.
