What is Pretreatment?
Pretreatment means the treatment of wastewater by commercial and industrial facilities to remove harmful pollutants before being discharged to a sanitary sewer system. Depending on the processes, pretreatment may include installing a grease removal device, a sand/oil separator, a dental amalgam separator, a neutralization tank, or other device designed to remove pollutants.
The Pretreatment Department of SPR ensures that facilities are meeting their pretreatment requirements and ensures that the wastewater treatment plant and river we discharge to are protected.

Legal Authority
Facilities that are located in our service area and discharge wastewater for treatment are subject to federal, state, and local regulations. Additional authority is given within the City of Englewood and City of Littleton’s local wastewater utility ordinances.
The US Environmental Protection Agency (EPA) implements and enforces the Clean Water Act. Industrial Pretreatment regulations are part of the Clean Water Act and protects the treatment facility, collection system, utility workers and the environment from contaminants that may interfere with the treatment process or any harm resulting from toxic or dangerous pollutants. This authority is provided in the Code of Federal Regulations at 40 CFR 403.8(f)(2). The EPA, state, and both cities have approved the South Platte Renew’s pretreatment program which includes the ability to monitor, permit, and enforce industrial pretreatment regulations.
