Regulatory oversight of wastewater treatment is administered at the federal level by the Environmental Protection Agency (EPA) and at the state level by the Colorado Department of Public Health and Environment (CDPHE). The CDPHE issues the permit for the Metro District’s WWTF. Permit structure is complicated as it specifies and defines all of our operational parameters and requirements. These include a long list of permit limits for the effluent stream that must be continuously monitored, measured, and reported to the CDPHE. Our operations staff does a phenomenal job of optimizing WWTF processes and operation and of ensuring that we always meet regulatory compliance.
