Where the city's sewer main ends and your lateral begins
Thornton inspects its sewer mains with cameras for roots, runs six lift stations and sends the flow to Metro Water Recovery for treatment, according to the city's wastewater page. Reports of sewer problems and after-hours emergencies go to its utilities operations line.
The lateral from your house to the main is yours. A camera pass from the cleanout shows whether roots, a belly or a cracked joint is the cause. You can also compare sewer line replacement steps on its own page.


Plumbing permits in Thornton: what the city says
