Utilities and Infrastructure Colorado 3 Minutes Read ยท published February 09, 2026 Flag of Colorado

Aurora, Colorado businesses that discharge to the municipal sewer must meet local and federal limits to protect public health and the sewer system. This guide explains where limits come from, how Aurora enforces them, typical violations, and practical steps for compliance including monitoring, permits, and reporting. It is aimed at facility managers, environmental coordinators, and consultants working with commercial and industrial dischargers in Aurora.

Understanding Sewer Discharge Limits

Sewer discharge limits set maximum concentrations or loadings for pollutants sent to the sanitary sewer. Limits may come from the City of Aurora municipal code, local wastewater utility permits, and federal pretreatment standards. Businesses should check the controlling municipal ordinance and any local permit conditions to confirm numeric limits and sampling requirements. See the City of Aurora municipal code for local sewer rules and definitions.[1]

Check permit conditions first when evaluating your compliance obligations.

Common Regulatory Requirements

  • Sampling and monitoring schedules, typically requiring periodic composite or grab samples.
  • Reporting and discharge monitoring reports (DMRs) or similar submissions to the utility.
  • Pre-treatment standards for specific pollutants (e.g., heavy metals, pH, oil and grease) where applicable.
  • Record retention and access for inspection by the utility or its agents.

Penalties & Enforcement

Aurora enforces sewer discharge rules through municipal authority; enforcement can include fines, administrative orders, and termination of sewer access. Specific monetary fine amounts are not specified on the cited municipal code page and should be confirmed with the city enforcement office. [2]

Repeated or continuing violations commonly trigger escalating enforcement actions.

Key enforcement elements to expect:

  • Fine amounts: not specified on the cited page.
  • Escalation: first, repeat, and continuing offences may be treated increasingly seriously; specific ranges are not specified on the cited page.
  • Non-monetary sanctions: administrative orders, required corrective actions, suspension of discharge privileges, and referral to court.

Compliance Steps for Businesses

Follow a documented compliance program to reduce risk and demonstrate good faith to the utility.
