Installing Underdrains in Areas with High Groundwater Levels

Underdrains are common in water filtration systems, but they can be useful for other purposes as well. One of these is controlling water filtrationgroundwater in areas with high groundwater levels, as this can put people and structures at risk if left unsolved. Here's how installing underdrains can help manage and regulate high groundwater levels.

They Keep Groundwater Down


Surfacing groundwater can be a problem, especially during and after storms. During these times, the rain pours down and fills up all bodies of water on the surface, as well as groundwater reservoirs. The ground stays wet longer, which can cause landslides, mudslides, and other hazards. With underdrains, the groundwater gets redirected somewhere else so the water stays below the ground.

They Make the Ground More Stable

Too high a groundwater level can make the ground move more, making it risky to put anything on it. This becomes a problem for existing structures and properties, transportation, and even living things. Because underdrains can filter water from the ground and make it drier, the turf becomes more stable. This is why it's ideal to place them near slopes, where the ground is also likely to move because of gravity and erosion.

They Help Plants and Buildings Stay Still

Sure, plants need water to thrive, but they also need air in the ground so they can breathe. Some crops can actually die if the ground remains waterlogged. Also, the instability of the ground caused by the excess groundwater can make buildings and other similar structures sink continually. As underdrains can control the water level, they can help plants stay alive and buildings stay still above ground.

Underdrains are useful beyond the usual water filtration system they're usually connected to. Their impact on the safety of an area for properties and people is quite impressive. If your company is part of the development of a particular area and you need to control high groundwater levels, think about installing underdrains as part of your project requirements.
