The City of Thornton Wastewater Collection System maintenance staff is charged with protecting the public's health and safety by maintaining the integrity of the new and existing system. The maintenance team is responsible for monitoring the condition of the wastewater infrastructure through tv inspection for root intrusion, breakage, and infiltration. Washing of sewer lines ensure that lines are free of obstructions.

Sewer taps are scheduled and performed for new development. The City also inspects six sewage lift stations twice per week and emergency generators are exercised weekly to provide reliable operation.

If you have problems or questions about sewer lines, email us or call Utilities Operations at 720-977-6500.
