If lift stations are not operating properly, there is a potential for wastewater backups into nearby homes. Watch for alarms such as a red light at the top. If you see the alarm going off or hear a buzzer, please call the Public Works Department immediately to report a lift station alarm. All lift stations have a sign with the station number and address on them. Please provide this information when reporting an alarm.
- Each year, the Public Works cleans approximately one-fifth of the city’s sanitary sewer lines. Lines requiring a higher level of maintenance are cleaned annually. This routine maintenance helps to prevent blockages and backups.
Sanitary Sewer Cleaning
The sanitary sewer lines are cleaned using high performance sewer cleaning equipment. A cleaning nozzle is propelled from one manhole to the next using water under high pressure The nozzle is then pulled back to the starting manhole. As the nozzle is pulled back, water scours the inside of the sanitary sewer pipe. Any debris in the pipe is pulled back with the water. The debris is removed from the manhole with a vacuum unit. If roots are found, they are cut with a root cutter. This process is repeated on every sewer line cleaned.
