Industrial Pretreatment


The primary function of the city's Industrial Pretreatment Program (IPP) is to prevent the introduction of pollutants into the sanitary sewer system that could interfere with the operation of the Waste Water Treatment Plant (WWTP), cause damage to the sewer system, or pass through the treatment plant to the Uncompahgre River. The WWTP is primarily designed to treat domestic sewage and non-domestic waste water has the potential to harm the biological treatment processes used at the plant.

Regulation of businesses and industries through the Industrial Pretreatment Program ensures the protection of the environment and the safety of wastewater treatment personnel and the community.

Issuing discharge permits, performing site inspections, monitoring discharges, and enforcing pretreatment standards and requirements provides the necessary protection.

Program experts help increase local awareness by educating businesses about program requirements. Current and accurate resources such as best management practices, manuals, regulations and local limits are made available to anyone.

The responsibilities of IPP are to:
  • Administer pretreatment discharge permits, and enforcement.
  • Enforce applicable United States Environmental Protection Agency categorical standards.
  • Maintain an active Industrial Waste Survey.
  • Monitor, assist, sample, and inspect local businesses and industries for compliance.
  • Prevent the introduction of pollutants into the Publicly Owned Treatment Works that could pass through the treatment works or be incompatible with treatment operations and / or the use or disposal of biosolids.
  • Protect the general health and safety of WWTP collection system employees.
  • Provide education regarding best management practices, pollution prevention, and waste minimization.
  • Respond to illicit discharges to the sanitary sewer system.
