Dewatering and construction dewatering are terms used to describe the action of removing groundwater or surface water from a construction site through deep wells or well-points. Normally the dewatering process is done by pumping or evaporation and is usually done before excavation for footings or to lower the water table that might be causing problems excavations. The most common dewatering methods used frequently involves the use of submersible dewatering pumps, centrifugal trash pumps, educators, or application of vacuum to well points.
When rehabilitating sewers, the flow cannot simply be diverted. It must be bypassed — temporarily pumped around the pipe being repaired or replaced. This requires pumps capable of moving trash-laden wastewater. The pumps are deployed up-stream from the faulty pipe, and a temporary pipeline is installed from the pumps to a downstream section of the sewer. Temporary plugs set in place between these points allow the pipe to be removed or repaired. Depending on the number of homes or businesses the line serves, the bypass may range from a few gallons to several thousands of gallons per minute.
