Underground utilities can be a mystery since most people don't see them on a regular basis. Even though its out of sight, the sewer system is an essential requirement for public health and sanitation. The Public Works Operations division manages the daily maintenance of the sanitary sewer collection system.
Public Works conducts a preventive maintenance program to 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. Public Works utilizes a pressurized cleaner truck to clean sanitary lines and remove deposits and material to ensure all sanitary lines remain operational throughout the City. The lines are also inspected with a televised inspection unit to examine and asses 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.
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.
Any Sanitary lateral that crosses 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.
