Lift stations contain the pumps, valves and electrical equipment necessary to move sewage from low to high elevation, making them an essential component of many municipal sewer systems. Here are several stations on the market, along with the individual components that keep them operating, including pumps, meters, valves, control panels and SCADA systems.

Lift Stations/Components

  Vertical auger screen

The Vertical Auger Monster screening system from JWC Environmental fits inside pump stations to screen, clean and convey debris straight up and out of the sewer system before they can clog pumps, eliminating the time and expense needed to de-rag. When attached to the wall of the pump station next to the influent pipeline, it captures rags, wipes, plastics and trash before they get inside the wet well. A custom-built screen fits every site and can screen up to 1 mgd. It can also be installed as a headworks screen for small treatment plants or lagoon systems. 800/331-2277;

  Fiberglass shelter

Strong, lightweight, super-insulated fiberglass shelters from Orenco Systems safely house lift stations, equipment, chemicals, controls and workers. Standard sizes are 8 feet tall, 4 to 16 feet wide and up to 42 feet long. Features include structural foam-core fiberglass walls (2 to 4 inches thick); weatherproof, watertight structure; insulation value up to R24; a high resistance to chemicals and corrosion; a roof structure rated up to 100 psf; and field or factory assembly. Custom options are available, including skid-proof floors, windows, roll up doors, HVAC, load centers, multi-color schemes and OLS control panels that contain integrated variable-frequency drives, which can optimize lift station operation and reduce energy usage by reducing hard starts and water hammering. Multiple drives can be configured for access through one user-friendly, easy-to-understand human-machine interface. 800/348-9843;

  Lift station inside drops

The use of controlled inside drops in lift stations from RELINER/Duran allows pump life to be extended by preventing aerated influent from being directly drawn into the pumps, the primary cause of cavitation. Their use can lead to dramatic reductions in pump-related problems, as well as reduced general maintenance and odor complaints. The drop pipe should always be extended below the low limit level and cut to follow the slope of the base fillet. If there is no fillet, cut the pipe at 45 degrees and in all cases maintain a distance from the floor or fillet of one pipe diameter. This will create a diffuser by directing the flow back against the structure, thus deaerating the influent. The simple arrangement is easy to maintain, as there is nothing to collect rags and debris and they can be cleaned from above. 800/508-6001;
