The Lift Station Division provides the pumping of raw sewage from the gravity sanitary sewer system to the City’s 4.0 million gallons per day (mgd) Wastewater Treatment Plant. At present, lift station personnel maintain 59 lift stations within the City’s service area. These lift stations range in pumping capacity of 1,000 gallons per day to 500,000 gallons per day. The City’s operations and maintenance program of these lift stations ensures constant performances through daily checks and data collection. This information provides vital data in the operations of each lift station.

Through this data, staff can determine a problem in normal operations then take corrective action before any serious problems can occur. Staff is on call 24 hours a day, 7 days a week, 365 days a year to ensure that these vital links within the sanitary sewer collection system continue to function, which helps to ensure the safety and welfare of the public and the environment.

The following are some of the standard daily, weekly and monthly activities that lift station staff perform to insure these lift stations provide uninterrupted service:

Daily hours of pump operations
Control panel operations
Pump/motor performance
Alarm system functions
Cleaning of control floats
Emergency generator operations
Electrical component operations
Grease removal from wet wells
Scheduled pump/motor rebuilding
Through the efforts of staff, the Lift Stations Division maintains electrical components, pumps/motors and control parts, as standard inventory. This inventory is used as required to maintain constant lift station operations, with out interruption of service. By providing staff with key lift station components and through the City’s proactive operations and maintenance program.
