Inground Pools and Ground Water: How To Manage A High Water Table (Video)

Inground Pools and Ground Water: How To Manage A High Water Table (Video)

Installation & Construction  |  Pool Videos

If you live in an area with a high water table, you may be wondering if a pool installation is possible, or how to manage ground water during the installation of an inground pool.    


In the video, we are installing a Cathedral 36 inground fiberglass pool on site in the Northern Neck of Virginia on a project where we encountered ground water. Fortunately, we had our camera equipment handy, so we covered how we typically manage a pool excavation and installation in a high water table area.  

The severity of the ground water on this project was relatively mild, but the same principles apply regardless of the severity.  


Guidelines For Managing Ground Water On An Inground Pool Project

1.  Start excavation from the deep end if possible.  This will ensure the ground water constantly flows to the deep end of the excavation where it can be pumped out instead of pooling against the dirt as it's being removed.

2.  Excavate at least 12" below the depth of the pool for the future drain pipe (also called sump pipe, dewatering system, or well pit).  

3.  Place several inches of clean stone/gravel in the sump pipe area and place a submersible pump to begin removing ground water. Be sure to discharge water far away from the excavation. More than one pump could be required, or a larger pump than the one shown in the video.   

4.  Silt fence can be used as shown in the video to prevent sediment from washing into the floor of the excavation. This will reduce the chance of substantial cave-ins.  

5.  Continue removing ground water until the concrete deck/surround is poured.
