Dewatering is an essential part of many construction projects.
It ensuring that sites remain stable, workable, and compliant with environmental regulations.
The process involves extracting groundwater, surface water, or trapped liquids from excavated areas to ensure structural stability of the project. Without proper dewatering, waterlogged soil can lead to structural failures, delayed timelines, and safety hazards such as trench collapses.
Traditionally, dewatering is performed using submersible dewatering pumps, wellpoints, or ejector systems, but one of the most challenging aspects is handling sludge, which is a semi-solid mixture of water, silt, clay, and organic matter. Sludge accumulates in excavations, trenches, or sediment basins and must be removed before construction can proceed. However, transporting and disposing of sludge in its natural state is expensive and inefficient due to its high water content. This is where sludge dewatering becomes essential, as dewatering reduces the volume by up to 80%, making it easier and cheaper to transport and dispose of.
NovaGeo’s NovaTube provides a solution to the slide dewatering system. This geotextile tube promotes cost-effective dewatering systems by reducing the need for multiple handling stages, minimising labour, and speeding up the process. The result is a cleaner, more manageable site that supports faster construction timelines and improved project outcomes.

FAQs
Dewatering is the process of removing water—typically groundwater or surface water—from a construction site, excavation, or mine to create a dry and stable work environment. This is done using methods like pumps, wellpoints, or drainage systems to prevent delays, ensure safety, and support structural integrity during construction activities.
The purpose of dewatering is to remove excess water from soil or sludge at construction sites to create a dry, stable, and safe work environment. This process prevents structural issues, facilitates excavation and foundation work, reduces environmental risks, and helps comply with regulations by managing water and waste efficiently.
