What We Do

Preventive Maintenance & Cleaning Crews

The Sewer Department's aggressive preventive maintenance program ensures that sewer mains remain in proper working order and prevents many problems before they occur. Hydraulic sewer jet cleaners are used to clean sewer lines with high pressure water hoses removing grease, grit and other debris from the lines. These sewer jets are also equipped with hydraulic root saws that are used to cut tree roots from main lines where roots are a problem. In addition to cleaning sewers these crews also respond to stoppage complaints. The program's goal consists of routine cleaning every public sewer main in which an obstruction may result in a backup into a residence or business. The routine cleaning frequency for these lines is intended to be at least a minimum of once every two years.

Mainline Stoppage Crews

The Sewer Department provides 24 hours a day seven days a week service in response to reports of sanitary sewer backups and overflows. Upon being notified of a problem, a two-person crew with a hydraulic sewer jet cleaner is dispatched to the location. Generally the crew will contact the complainant to determine the nature and extent of the problem. The crew then inspects and cleans any sewer 6 inches in diameter or larger which could remedy the problem. Any obstruction determined to be in a public sewer is followed up with an internal TV inspection of the sewer line. In most cases, after a complete review of the incident, the location and the cause of an obstruction can be determined. If the problem is in the customer's line, the Sewer Department will attempt to open the blockage with a sewer tape temporarily, and will advise the customer to contact a plumber or sewer service company.

Closed Circuit Television Inspection

The Sewer Department uses a state of the art closed circuit television system to internally inspect sewer mains and service line connections. This system consists of a color camera with a pan and tilt head which can turn 90 degrees in any direction and is self propelled through sewer lines transmitting a picture to a monitor and video recorder located inside a trailer. Using this system, problems can be located and identified quickly and without excavation so that proper corrective actions can be taken.

Repair Crews

The Sewer Department operates two repair crews. One crew is responsible for repairs to manholes. The other crew is responsible for repairs to sewer mains. Excavations have been up to 20 feet deep. These crews repair sewer mains that have been determined to be in poor condition by TV inspection that was done following a stoppage or because of a problem suspected during routine cleaning.

State-of-the-Art Methods

The Sewer Department is constantly seeking methods to do jobs that are safer, more cost effective, and at a minimum inconvenience to our customers.

When conditions warrant, sewer lines can be rehabilitated by several different methods of internal trench-less rehabilitation, eliminating the need for open excavation. This system takes only hours as opposed to days for conventional methods.


The Sewer Department places much emphasis on accountability of its activities and functions throughout the year. To provide this service, daily reports are compiled to maintain a record of all work and can be used to capture labor costs, equipment costs, and material costs for all jobs, projects, and activities.

Producing and storing these kinds of reports enables the Sewer Department to monitor its work activities and its production, also making it possible to better serve you and the community.
