Water problems are a common problem in construction sites and can halt work. Stormwater, groundwater infiltration and nearby sources of water tend to accumulate in the excavations and weaken the soil. Ineffective water management slows down work and raises safety hazards for workers, machinery and ground support systems. 

Good dewatering planning keeps the ground conditions stable and work progressing well. It also minimizes structural risks and expensive delays. This guide includes an overview of dewatering pump types and more.

What Type of Dewatering Pump Is Best for Construction Sites?

The best dewatering pump for your job is based on the conditions of the site. The decision is affected by numerous factors, including soil, water volume, trenching depth, power available and project duration. Temporary and permanent applications both demand quality equipment, but the latter also requires longevity. 

Submersible Dewatering Pumps

Submersible dewatering pumps work while underwater. They are located in a sump, pit or flooded excavation. These pumps are great for removing water from large areas and are easy to install. They are also small enough to fit in tight spaces such as basements and ditches. They operate quietly because they work underwater. 

Diesel Dewatering Pumps 

The internal combustion engine is the driving force of diesel dewatering pumps. They are used extensively at job sites without electricity or where power is inconsistent. These pumps provide a solid handling capability and can be used for large-scale open excavation in quarries. They’re able to cope with mud and debris well, but you will need to maintain your fuel and engine regularly.
