Dewatering Pump Selection Guide

Dewatering can range from a simple process to a full complex system, but DAE Pumps can help you select the right pumps for your needs. Whether you expect to use your pump daily or just a few times a month, many different types and sizes that can handle the job, but which one? How do you choose which dewatering pumps are right, which cannot do the job, and which are a complete overdo?

What is Dewatering? 

Dewatering is the process of removing water or other liquids, typically surface or groundwater, from a specific location like construction sites, riverbeds, mines, tunnels, flood zones, and other areas where water can accumulate. Dewatering refers to reducing the level of water from the soil with the primary intent of draining water. In many cases, heavy rains cause water to gather in a location that it is not wanted and digging, excavating, or mining below the water table will also create a consistent influx of water requiring dewatering. In some cases, water is used for drilling processes, and the accumulated water has to be pumped out which requires dewatering pumps. Also, dewatering may be required for lakes, ponds, canals, and other waterways construction projects, or even for broken water or sewer pipelines.

Flood Pump

Dewatering Methods

One of the simplest methods for dewatering is digging channels to release water, but that requires additional landscape reconstruction and, in most cases, not an option. The most popular type is pumping. Pumps provide complete control over where water is discharged without altering the formation of the land and can move the liquid safely and quickly. There are a variety of pump types that can do the job, but the style of the pump depends specifically on the situation.

DAE Pumps offers the widest range of dewatering pumps that can be deployed in various ways for optimal performance for any project condition. Our dependable submersible pumps and self-priming pumps are ideal for dewatering applications like flood control, wellpoints, deepwells, bypass, and tunneling.

Flood Control

Flooded

Pumping harmful stormwater caused by heavy rain and flooding is essential for reducing and removing water from construction sites, roads, mines, tunnels, canals, rivers, and other affected areas with increased water levels. Excessive rainfall fills holes in the ground and raises water levels higher than capacity causing damage and destruction that can be very costly. Using submersible or self-priming pumps can quickly remove water that has accumulated after rainstorms, and proactively can be set-up to divert water from known trouble spots to reduce or eliminate damage.

Wellpoints / Deepwells

Deepwell

Wellpoints and deepwell dewatering principles are very similar. Wellpoints are a series of small wells drilled around a specific site for suctioning out groundwater. Deepwells are individual well, typically at deep construction sites with large portions of water for pumping out. Both applications can use a self-priming dewatering pump located at the upper end or a submersible dewatering pump located at the bottom of the well where the groundwater is at, and both work well for these applications.

Bypass

Bypass Sewer

Bypass dewatering is the process of redirecting water or other liquids around a trouble area. Typically, bypass dewatering is used for a pipe break. A self-priming pump or submersible pump suction liquid left because of the broken pipe and transport the liquid past a damaged pipeline location to another section of pipe further down the line. Reliable pumps and properly fitted hoses are essential in the case of broken sewage lines. DAE Pumps makes reliable high-pressure pumps that work fast.

Dewatering Pumps

DAE Pumps manufactures a variety of pumps for any of your dewatering needs. Our most common pumps are submersible dewatering pumps and self-priming water/dewatering pumps. Both types come in a variety of sizes and power. We provide pumps specifically designed to transport just water and other liquids, and we also carry more durable pumps that can withstand mud, sludge, and abrasive materials that can clog and destroy the pump.

When looking for the right dewatering pump, it is essential to look at the application you are looking to use it for, the type and amount of material you are looking to move, and the type of pump. The economical submersible dewatering pumps are electric and available in the sizes you need, and we also supply multiple sizes of economical self-priming diesel and electric water/dewatering pumps. It is important to stress again that in many of these dewatering applications, you must be careful not to intake slurry, tailings, mud, and other materials, as these items can destroy dewatering pumps. 

Debris intake will typically occur as the water level goes down. Most abrasive material will hammer away at the impellers, and thick sludge will clog the pumps. For these applications, DAE Pumps recommend a heavy-duty line of slurry pumps.  These lines of pumps are non-clogging and transfer solids up to 70% viscosity.

Dewatering Applications

At many construction sites and utility installations, water is an unwanted element. Water is damaging, slows down production, and can be very costly for commercial and industrial building construction sites. Construction site dewatering is essential after rainstorms to getting back to the building. For mining, water can be critical in the operations, but the management of it can be challenging.

Mine dewatering can mean reclaiming process water for reuse or removing excess water from the pit. A comprehensive, reliable, and flexible dewatering plan is essential to ensuring there is a steady supply of process water throughout the site. Conversely, the removal of excess water from working areas to allow excavation to continue whilst safeguarding the operators and maintaining productivity also requires a dewatering plan.
