In order for a proper dewatering process to happen, it is important to take things into consideration. Dewatering precautions, methods and damage prevention need to be taken into account in order for your dewatering process and construction project go on without a hitch.

Dewatering Precautions

In order to get a dry worksite, it is imperative to take precautions. Some things to pay close attention to while dewatering is:

  • Water is not being pumped directly into slopes
  • Continue dewatering if the area is showing signs of instability or erosion
  • Avoid dewatering if there are or has been heavy rains
  • Never discharge water that has been contaminated with oil, grease, or other contaminants
  • Check local, state, and federal agencies for proper permits  

Dewatering Methods

There are several different dewatering methods, but it is best to use one that is perfect for a multitude of different dewatering projects, like the Aqua-Barrier Water Inflated Dam. The Aqua-Barrier® cofferdam is an inflated, water-filled device essential for controlling surface water up to 6 feet deep. They are environmentally safer than traditional sandbags, they are reusable and provide for compact storage, transportation, and ease of handling.

Water Damage Prevention

When you’re removing water or lowering the groundwater level, the extraction of water alters the characteristics of the surrounding soil. You must be aware of how this change impacts your excavation. If this is not done properly, the resulting instability will cause problems for you and the owners of the surrounding property.  You also must be aware of and take responsibility for the safe relocation of the water.

ProTip: The Aqua-Barrier Cofferdam is the perfect way to ensure water is removed from a worksite without further damaging the work area.

The Importance of Proper Construction Dewatering

Having a proper construction dewatering plan is imperative to keeping your project on schedule and on budget. Construction dewatering can be very challenging and normally includes the removal, treatment, and discharge of groundwater and stormwater. Make sure you have a solid plan and the best tools for the job.
