We have also invested heavily in our health and safety processes, becoming members of CHAS, British Safety Council and Safe Contractor Approved.

Technical Aspects of Construction Dewatering

Construction dewatering is a nuanced process, vital for maintaining the structural integrity of your excavations. It involves the removal of groundwater or surface water through methods such as wellpoint systems, deep wells, and sump pumping. The choice of technique is crucial, influenced by factors including soil type, water volume, and environmental considerations.

Our wellpoint systems involve closely spaced wells connected to a header pipe, suitable for shallow excavations and offering minimal disturbance to surrounding areas. In contrast, deep wells are more suited for significant water volume removal, utilising submersible pumps to control groundwater levels for larger or deeper sites.

Our experience in dewatering services

Our commitment to excellence is evident in our track record. For instance, our involvement in a range of projects has required a complex dewatering strategy. Examples of these complexities include proximity to protected wetlands and using an innovative approach to ensure groundwater can be used for dust control and other construction needs.

In all our dewatering projects, our team ensure we are acting in the most eco-friendly and efficient way. 

Environmental and Regulatory Compliance:

We recognise the environmental implications of dewatering, and our strategies are designed to minimise ecological impact. Our systems include sediment control measures, ensuring that discharged water is free of contaminants, protecting local waterways. Furthermore, we strictly adhere to regulatory standards, conducting thorough site assessments and obtaining all necessary permits before commencing dewatering operations. 

FAQs about construction dewatering

What is construction dewatering?

Construction dewatering is the process of removing unwanted water from a construction site, typically necessary for excavations below the water table to prevent flooding or structural failures.

How does soil type affect dewatering?

Soil characteristics heavily influence dewatering methods. For instance, granular soils permit easier water flow compared to clay-heavy soils, impacting the technique and equipment used.

Why is dewatering necessary?

Dewatering is crucial for providing a safe work environment. Excess water can weaken foundations, cause trench collapses, and turn the site into a muddy, unworkable mess. By controlling the water level, construction can proceed safely, efficiently, and within the set timelines.

What are the common dewatering methods?

Several techniques are used, depending on the site’s conditions. Common methods include sump pumping, where water collects in pits and is pumped out, and wellpoint systems that draw water through spears inserted into the ground around the excavation site. Other techniques involve the use of deep wells and ejector wells, especially for more profound or more complex excavations. 

Does dewatering have environmental impacts?

Yes, improper dewatering can lead to erosion, sedimentation, and the disturbance of local water bodies. It’s vital to use sediment control measures and comply with environmental regulations to mitigate these impacts. 

How long does dewatering take?

The duration depends on several factors, including the project’s size, the water table level, soil conditions, and the chosen dewatering method. It could range from a few days to several weeks or even months for extensive projects.

Understanding these aspects ensures that construction dewatering is conducted efficiently, safeguarding both the project’s integrity and the surrounding environment.

Alongside our construction dewatering services we also offer industrial waste management services which often work in conjunction together.
