In the video, the speaker Jeff Davis walks us through the process of well dewatering. Temporary well dewatering is done to lower the water table in an area to enable work to get done below the water table. It is usually done to allow the installation of pipelines.

Choosing the right pump for the job is a key element to the project’s success.

Planning the Dewatering Operation

Before starting the dewatering process, pertinent information needs to be gathered. Information about where the water table is, how much it needs to be lowered, and what kind of soil is in the area. Permits for temporary lowering of the water table also must be obtained. Planning includes deciding how many wells need to be drilled to lower the water table, how far apart they will be spaced, and how deep they will be. At this time, engineers also establish the size and positioning of well slots that will connect the wells and allow water to flow through them.

Choosing the Correct Pump

The choice of the pump will depend on how much water needs to be moved vs. the pump’s performance. Other considerations are the design and size of the pump and its ability to withstand abrasions and corrosion to survive the duration of the job.

Well dewatering is a specialized job that needs to be done by knowledgeable people. Let a team of professionals consult on your project to help you choose the best type of pump for the job.
