Overview

Sanitary sewers carry wastewater from sinks, showers, and toilets away from neighborhoods to treatment facilities.  Public Works manages performs and cleaning to keep all sanitary sewer lines in good working order.  Even though it's out of sight, the sewer system is an essential requirement for public health and sanitation.  image of a sewer lid

Public Works crews actively inventory, assess, clean, and address trouble spots throughout the sanitary sewer system and continuously repairs sections as needed in order to deliver reliable service.

  • A pressurized cleaner truck cleans the sanitary lines and remove deposits and material to ensure all sanitary lines remain operational throughout the City.
  • A televised inspection unit examines and assesses the condition of the pipes.
  • Rating and assessing each public sanitary line allows Public Works to determine the service life remaining in each line before they need to be replaced and helps prioritize the sequence of lines to replace.

Maintenance Responsibility

The City's sanitary sewer system consists of 258 miles of sewer main lines distributed throughout the City. Laterals extending from the homeowners and private businesses property and connect to the public sewer main lines are considered private utilities and are the homeowners responsibility to maintain.

Access

Any Sanitary main line crossing over more than one property line and has more than one connection to it is considered a public line that the City is required to maintain. These unique combinations do occur throughout the City and also requires the City to have an easement recorded for access with each affected property. These easements can be found on residential and commercial private properties, however they have been established to allow the City to have access to the public sanitary sewer line for maintenance purposes. If you have an easement on your private property, please understand that at some point in time the City will need access to this utility to possibly inspect, clean, or replace the underground sanitary line.
