Another mode of system failure can include power outages, which may disable lift station pumps and cause sewage overflow from the lift station wet well. Lift station mechanical or power failure causes approximately ten percent of United States SSOs. This type of discharge is uncommon from combined sewers, because the combined volume of sewage ...
When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4]
A force main or rising main [8] is a pumped sewer that may be necessary where gravity sewers serve areas at lower elevations than the sewage treatment plant, or distant areas at similar elevations. A lift station is a sewer sump that lifts accumulated sewage to a higher elevation.
Corpus Christi police continue their investigation of human remains that a Corpus Christi Water employee found Monday at a wastewater collection point, saying the remains bear "no obvious sign of ...
The normal flows coming into the wastewater treatment facility are about 1.3 million to 1.5 million gallons per day, said Jim ... Sump pump discharges in Jamestown increase lift station work Skip ...
The main purpose of wastewater treatment is for the treated wastewater to be able to be disposed or reused safely. However, before it is treated, the options for disposal or reuse must be considered so the correct treatment process is used on the wastewater. The term "wastewater treatment" is often used to mean "sewage treatment". [4]
Sanitary sewer overflow is a condition in which untreated sewage is discharged from a sanitary sewer into the environment prior to reaching sewage treatment facilities. Manholes are common locations of sanitary sewer overflows. The causes of overflows may be from excessive infiltration and inflow, or blockages.
Small-scale sewage pumping is normally done by a submersible pump. This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.
