How to Dewater a Construction Project


Every location has a rainy time whether daily or during certain months. Unfortunately, construction companies need to take advantage of the dry times as much as possible. When water builds up and puddles, working space is limited. Dewatering is an essential way to continue working one any outdoor project.

One way to dewater a construction site is through pumping. This is a technique used by wastewater treatment companies as well. When building large projects such as treatment centers, often the company has to dig deeper to support the base of the building. The groundwater needs to be pumped out to properly level the ground. Sump pumps still need pre-drainage techniques to keep other stability issues at bay.


Protecting the groundwater is crucial for any construction site. Not only does it decrease the chance of being hit with a pollution lawsuit, but it keeps overall costs lower. Those fewer costs can help you stay on project target for a profit. Careful planning and implementation are crucial to the success of the dewatering project. Sites may need excavation to build a stable foundation. Thus, construction companies must control the groundwater while still protecting the water source.


Before dewatering any project, be sure to follow some key precautions. While some of these may seem like common sense, failure to plan for these can end in disaster. Remember that sump pumps only remove small amounts of water at a time. If you have a large area, you may need a larger system or to reevaluate the dewatering method. Keep an eye out of erosion and instability during dewatering. Carefully remove contaminated water and properly handle it. Pumping on a slope is not advised. Heavy rains are not the ideal time to dewater. Some municipalities may require the construction site to have permits or requirements in addition to those already in place. Keep the groundwater beneath the construction site a top priority. These precautions can ensure the dewatering works well.
