From Sediment to Sustainability: The Benefits of Dewatering Bags on Construction Sites

Updated: Jun 27, 2023

Dewatering bags are a popular solution for managing water on construction sites, and they are often used to filter and remove sediment and other pollutants from water before it is released into the environment. These bags are made from a permeable geotextile fabric that allows water to flow through while trapping sediment and other contaminants. In this blog post, we will explore how dewatering bags work and their benefits for construction sites. We will also discuss the environmental importance of using dewatering bags and how they can help prevent pollution and protect our natural resources.

How Dewatering Bags Work

Dewatering bags are designed to capture sediment and other contaminants from water as it flows through them. The bags are typically made from a high-strength, permeable geotextile fabric that allows water to pass through while trapping sediment and other pollutants. The bags are available in various sizes and capacities, depending on the needs of the construction site.

To use a dewatering bag, construction workers will typically set up a sediment control barrier or fence around the perimeter of the site to prevent sediment and other pollutants from entering nearby waterways. Water is then pumped into the dewatering bag, which filters out sediment and other contaminants, leaving cleaner water to be discharged. The sediment and other pollutants that are captured by the dewatering bag can be disposed of properly, often by being sent to a landfill or reused in other ways.

Benefits of Dewatering Bags for Construction Sites

There are many benefits to using dewatering bags on construction sites, such as:

  • Help prevent pollution by filtering out sediment and contaminants from water

  • Protect nearby waterways from pollution

  • Ensure compliance with local and federal environmental regulations

  • Easy to use and transport

  • Available in various sizes and capacities

  • Customizable to meet site needs

  • Cost-effective compared to other sediment control methods

Environmental Importance of Dewatering Bags

Dewatering bags are an important tool for protecting our natural resources and preventing pollution. When sediment and other contaminants are discharged into waterways, they can harm aquatic life, impact water quality, and lead to long-term environmental damage. By using dewatering bags to filter out sediment and other pollutants, construction sites can help prevent these negative environmental impacts and ensure that nearby waterways remain clean and healthy.

Another environmental benefit of dewatering bags is that they can help prevent erosion. When water is allowed to flow unchecked on a construction site, it can erode soil and cause sediment to enter nearby waterways. By using dewatering bags to capture sediment and filter out pollutants, construction sites can prevent erosion and protect the surrounding environment.


Dewatering bags are an effective and cost-efficient way to manage water on construction sites. By filtering out sediment and other pollutants, dewatering bags can help prevent pollution, protect our natural resources, and ensure that construction sites remain in compliance with environmental regulations. Their environmental importance cannot be overstated as they help prevent erosion and protect aquatic life. If you are planning a construction project, consider using dewatering bags as part of your sediment control plan.
