GATOR’s dewatering pumps efficiently remove water from areas where it is unwanted with a rotating impeller that draws water into the pump and away from the area. Here, we’ll take a closer look at what mechanical dewatering pumps do, some common industrial applications for them, and what to consider when selecting a pump for your application.

What are Dewatering Pumps?

What are Dewatering Pumps?

Dewatering pumps are a critical tool for removing excess or unwanted water from areas where it hinders operations, causes damage, or threatens safety. These pumps work by generating suction to move water away from a site, typically through hoses and discharge lines. Dewatering pumps are commonly used in construction, mining, agriculture, flood recovery, and municipal projects to help maintain safe, dry, and efficient working conditions.

At GATOR Pump, we’ve been at the forefront of reliable dewatering for over four decades. Our pumps were initially designed to serve agricultural producers. Over time, we have expanded our products and services to meet the needs of many other industries. Built for efficiency, durability, and portability, GATOR Pumps operate in canals, ditches, ponds, and lakes, often without the need for suction lines, check valves, or priming. They can be configured as trailer-mounted, vertical, and 3-point tractor hook-up units for easy, one-person operation, even in the most challenging environments.

The Importance of Dewatering Pumps

The ability to safely and efficiently remove large volumes of water from an area is essential in many emergency and standard operating situations. Dewatering pumps are important for several reasons, because they:

  • Prevent work delays and damage to materials, soil, and equipment.
  • Ensure safe operating conditions.
  • Keep people safe from contaminated or dirty water.
  • Maintain dry conditions in enclosed areas.
  • Support municipal water management.

Common Dewatering Pump Applications

There are different types of pumps for different fluids, amounts of solid or sludge content, volumes of liquid to displace, and settings. Here are some examples of how dewatering pumps support various real-world needs:

Construction Sites

Construction projects often involve excavation below the water table or in areas that are prone to rainfall and runoff. Standing water in trenches and foundations can bring work to a standstill, compromise materials, and extend deadlines. Dewatering pumps quickly remove water so work can continue.

Mining Operations

In mining operations, groundwater ingress poses a safety hazard and can obstruct access to tunnels and pits. Dewatering pumps effectively manage this water, allowing crews to work safely and continuously extract materials.

Flooded Areas

From unexpected flash floods to hurricanes, dewatering pumps are a frontline tool in disaster recovery. They help clear basements, streets, and buildings of floodwater, which speeds up recovery and minimizes long-term damage to buildings.

Agricultural Drainage

Excess moisture in fields can suffocate crops and degrade soil quality. Conversely, excessively dry soil can lead to excess runoff if dry soil does not absorb water quickly. Dewatering pumps help keep things in balance to maintain stable growing conditions year-round.

Tunnels and Underground Structures

Tunnels, subways, and below-ground structures require consistent water management to avoid seepage and structural compromise. Dewatering pumps keep these spaces dry during construction and operation.

Municipal Water Management

Cities and towns use dewatering pumps to manage stormwater basins, prevent overflow in reservoirs, and support wastewater treatment facilities.

Industrial Applications

Industries from manufacturing to oil refining use pumps to remove water from containment ponds, processing systems, or storage tanks. This helps prevent equipment corrosion and improves operational efficiency.

Choosing the Best Pump for Your Application

The details of the application will always determine which type and size pump is most suitable for efficient dewatering. For example, a different type and size pumps will be used in each of these cases:
  • Dewatering water with a high sludge or solids content.
  • Draining large volumes of stormwater that accumulates quickly.
  • Deep ponds or reservoirs suitable for submersible pumps.
  • Centrifugal pumps for high speed pumping and high discharge volume.

There are several things to consider when selecting a pump, including:

  • Volume and depth of liquid: Submersible or non-submersible pump.
  • Flow rate: Quantified in gallons per minute.
  • Characteristics of the fluid being pumped: Solids and their size, sludges, viscosity.
  • Friction loss: Energy lost as fluid travels through a hose or pipe due to its size or material, or due to fluid viscosity.
  • Total dynamic head: Resistance the fluid encounters, or the amount of energy required to move fluid through the system.
