Industrial Pretreatment Program

The Industrial Pretreatment Program (IPP) is a program mandated by the Environmental Protection Agency. We are dedicated to ensuring the quality of the water discharged from Greeley’s wastewater treatment plant into the Cache la Poudre River and the quality of biosolids produced. In order to accomplish this, we address discharges from industrial and commercial users into the sanitary sewer system.

In addition to the required elements of our program, we implement educational activities that promote environmental awareness. Some of these activities include: Pollution Prevention through Elementary Education and a video about oil and grease for restaurant personnel.

The requirements of the IPP are:

  • To prevent the introduction of pollutants into the publicly owned treatment works that could pass through the treatment works or be incompatible with treatment processes.
  • To prevent the introduction of pollutants into the wastewater treatment plant and collection system that could interfere with treatment operations and/or the use or disposal of biosolids.
  • To improve the feasibility of recycling and reclaiming the municipal and industrial wastewater and biosolids.
  • To protect the general health and safety of wastewater treatment plant and collection system employees.
  • To enforce applicable EPA categorical standards
