Sewer service pipes from your home, school or business run out to the street where they then connect into the city owned and maintained sewer system. Property owners are responsible for the condition and operation of the service pipes on their property. We have provided some tips to help you maintain the condition of your sewer lines, which in turn also help the city avoid costly repairs to city sewer lines. See the link "What You Can Do."
The city has 225 miles of sewer in service throughout the city. These lines carry sewage to the city's wastewater treatment plant. Sewer pipe diameters range from 8 inches to 60 inches.
There are over 4,300 manholes located throughout the city. These manholes link into the sewer system and are a place where sewage pumps are installed.
A lift station is a pump or pump station. Sewers flow by gravity down a slope. When the sewer becomes too deep it flows into a manhole where there are pumps, which "lift" the sewage to a higher level. It then continues to flow by gravity toward the treatment plant.
There are 14 lift stations located through out the city. These stations have the capacity to pump 20,230 gallons per minute (total capacity).
Our maintenance goal is to clean & remove debris from pipes every 5 years for pipes that are 8 inch, 10 inch, 12 inch, and 15 inch in diameter. The city employs two crews with flushing equipment to work toward this goal.
