Sustainable Drainage Systems (SuDS)
Supporting Effective Surface Water Management Through Ground Investigation and Testing
Sustainable Drainage Systems, commonly referred to as SuDS, are designed to manage surface water runoff in a controlled and efficient way. Chelmer support SuDS design and implementation through detailed site investigation, testing and drainage assessment services, ensuring that systems are suited to the specific conditions of each site.
Effective surface water management relies on a clear understanding of ground conditions, drainage performance and water behaviour. By combining investigation techniques such as soakage testing, trial pits and boreholes, Chelmer provide the data required to support the design of suitable drainage solutions.
Understanding Ground Conditions for SuDS
The performance of any SuDS solution is heavily influenced by the characteristics of the ground. Soil permeability, groundwater levels and existing drainage infrastructure all play a role in determining how water can be managed across a site.
Chelmer carry out site investigations to assess these factors, ensuring that any proposed drainage system is based on accurate and site-specific information. This helps to avoid issues such as poor infiltration, waterlogging or system failure.
By understanding the ground conditions in detail, it is possible to design drainage systems that function effectively and meet project requirements.
Soakage Testing and Infiltration Assessment
Soakage testing is a key element in assessing the suitability of the ground for infiltration-based drainage systems. These tests measure how quickly water can be absorbed into the soil, providing essential data for the design of soakaways and other SuDS features.
Testing is typically carried out within trial pits, allowing results to reflect the conditions at the depth where drainage systems will be installed. The data obtained is used to calculate infiltration rates and to determine appropriate system design.
By integrating soakage testing into site investigations, Chelmer ensure that drainage design is based on reliable and representative data.
Drainage Investigation and System Assessment
In addition to ground testing, Chelmer assess existing drainage systems to understand how they interact with proposed SuDS solutions. This may include CCTV surveys, leak detection and tracing of drainage networks to identify any constraints or issues.
Understanding the condition and layout of existing drainage infrastructure is essential when planning new systems, ensuring that they can be integrated effectively without conflict or reduced performance.
This combined approach allows for a more complete assessment of drainage conditions across the site.
Supporting Design and Planning
SuDS are often a requirement for planning approval, particularly on developments where surface water cannot be discharged directly into main drainage systems. Accurate site data is therefore essential in demonstrating that proposed solutions are viable and effective.
Chelmer’s investigation and testing services provide the information required to support drainage strategies, ensuring that systems are designed in accordance with site conditions. This helps to streamline the planning process and reduces the risk of revisions at a later stage.
Integrated Approach to Drainage Solutions
Chelmer’s approach to SuDS is based on integration with their wider site investigation and drainage services. By combining testing, surveying and assessment within a single service, they provide a coordinated solution that supports efficient project delivery.
This ensures that all aspects of drainage design are informed by accurate data, reducing uncertainty and improving overall performance. Whether supporting small developments or larger projects, Chelmer provide the technical insight required to develop effective and sustainable drainage solutions.
