Pretreatment Program

NEW Water's Industrial Pretreatment Program regulates certain industries called Significant Industrial Users (SIU's) in order to control the introduction of pollutants into the sewerage system and ultimately our treatment facility. These SIU's must comply with federal, state, and local requirements through the use of a permit system. An Industrial Wastewater Discharge Permit outlines and references the requirements necessary to comply with all applicable wastewater regulations. Other requirements and guidelines are as follows:

  • Samples are collected by the SIU at their discretion and samples are collected by NEW Water unannounced to confirm compliance.
  • Facility inspections required at least once per year for each SIU to review operations.
  • Chemical inventories are recorded in quantities of five gallons or more.
  • In the event of a process change, chemical change or compliance issue, NEW Water may conduct addition inspections to gather necessary information.

Is your industry categorized as a SIU?

According to NR 211.03 (19m), Significant Industrial Users (SIU) are defined as the following:

(a) Any industrial user subject to the categorical pretreatment standards in chapters NR 221 to 297;

(b) Any industrial user which discharges an average of 25,000 gallons per day or more of wastewater to the POTW, excluding sanitary, noncontract cooling and boiler blowdown wastewater;

(c) Any industrial user that discharges to the POTW a process waste stream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant.

(d) Any centralized waste treater; or

(e) Any other industrial user designated as a significant industrial user by the control authority.
