Ancillary Structures Including Pump/Lift Stations

Wastewater pump/lift stations are facilities which contain a receiving well for the sewage flow from the properties or businesses. The sewage flow is screened or ground up to get rid of course materials and then sent through pipes using pumps to a point where it can be lifted up to a higher level. The sewage flow can once again move by gravity toward the sewage treatment plant. These units are frequently used in the centralized collection system to keep the sewage flow from the houses and businesses moving forward. The advantage of the lift station is that it reduces the cost of sewer system construction because the trenches do not have to be dug more than 10 feet deep. The disadvantage of this system is that power is required to operate the pump/lift station and there need to be individuals trained to maintain the system and pumps properly. There is also substantial diversity between the various components in the different systems including necessary sensors and control mechanisms. Pump stations can age the pipes when surges of sewage occur. The structures for these units are frequently underground and a combination of groundwater leakage and condensation may corrode steel supports and frames as well as other equipment. Also, if there is a failure in the power system, the pump/lift station may shut down.
