The District maintains and operates sixteen (16) pump stations. These pump stations range in size from lift stations serving small apartment complexes to larger regional size pump stations that may serve several neighborhoods or drainage basins. Current maintenance standards include weekly inspections of all pump stations. Follow up maintenance is done based on the field technician’s inspection of the pump station. Other inspections are done semi-annually or annually. The details of these inspections can be found in the performance measure for Pump Station Inspection (PSI). Pump station wet wells are cleaned and inspected every four (6) months. Wet wells are drained, the inside cleaned with high pressure water, and all floats, sensors and other hardware are washed down. The wet well and all apparatus are then inspected for wear or damage.
The District also maintains and operates eight (8) power generators that are permanently mounted, enclosed units at the pump stations and have automatic transfer switches. The District maintains two (2) large portable trailer-mounted generators. These generators are inspected and tested on a monthly basis. Power to pump stations with permanent generators is shutdown and the generator is allowed to engage and run for one hour. The portable generators are started and also allowed to run one hour each month.
