To ensure the safety and stability of a project, water well drilling contractors often conduct dewatering on construction sites. Essentially a way to control groundwater in a work zone, dewatering is an extraction process that uses a water pump to temporarily reduce groundwater levels to make excavation and other work easier and safer. Doing so can prevent flooding and subsequent delays in work. Here’s why it’s such a critical part of the construction process.

Why Dewatering Is Vital to Construction

How Is Dewatering Performed?

Dewatering is carried out using several different methods; the most common one uses a water pump. Before any area moisture has a chance to interfere with the excavation process, the pump collects the water in efforts to reduce the water table in the work zone. The water is then discharged in a safe area where it won’t erode or disturb the work site. Contractors may choose to use several water pumps at once on particularly large excavation sites. After the land is free of moisture, it’s safe for work to begin.

What Are Its Advantages?

Dewatering establishes a stable site for the construction of any type of building. Heavy soil saturation can lead to serious construction issues, and applying foundation to this type of surface may lead to moisture intrusion and structural problems. Dewatering also eliminates the contamination that might pollute any runoff in the groundwater supply.

This procedure also creates a safer and more productive work environment. Contractors can work with heavy tools and equipment far more easily when they’re moving them over dry, solid ground. Wet ground can also attract mosquitoes and other pests, which can contribute to a challenging work environment.

Are There Any State Rules to Follow?

In New Jersey, construction site managers must obtain a permit if they plan to dewater more than 100,000 gallons in a single day. The first step is to fill out a temporary dewatering permit application and submit it to the Bureau of Water Allocation & Well Permitting in Trenton. You’ll need to supply estimated start and ending dates, size of the project, proposed dewatering depth, and discharge location.
