Waste treatment of some kind has been practiced by civilizations for thousands of years. Nevertheless, rivers, lakes, and other waterways became polluted over time for a variety of reasons.

Pretreatment Program Mission

To protect the City's wastewater collection and treatment systems and the water quality of the Big Thompson River.

Pretreatment Program Vision

To ensure that non-residential customers' wastewater is adequately treated using reasonable control mechanisms and pollution prevention techniques.

Loveland Water and Power's Objectives:

  • To protect the City of Loveland's sewer system from pollutants that could interfere with the collection system or wastewater treatment plant (WWTP) processes.
  • To protect the Big Thompson River from non-domestic pollutants that could pass through the WWTP untreated, and ensure that the plant’s biosolids can be used as a soil conditioner and fertilizer.
  • To protect city employees from potentially harmful discharges.

Clean Water Act:

In 1972, the United States Congress pass the Water Pollution Control Act which stipulated broad national objectives to “restore and maintain the chemical, physical, and biological integrity” of the Nation's waters (33 U.S.C. 1251). The Water Pollution Control Act was amended in 1977 and re-titled the “Clean Water Act” (CWA).

Within the CWA, Congress established the Environmental Protection Agency (EPA). The EPA established the “General Pretreatment Program Regulations” in 1978. These regulations require many Publicly Owned Treatment Works (POTWs) nationwide, including the City of Loveland, to administer an EPA approved Pretreatment Program. The City of Loveland’s Pretreatment Program was approved by the EPA on September 9, 1985.

Chapter 13.10 of the Loveland Municipal Code sets forth the requirements for industrial users (IUs) of the City’s sewer system. All industrial users must provide wastewater treatment as necessary to comply with the ordinance.

Users classified as a significant industrial user (SIU) are required to obtain a wastewater discharge permit.
