Drainage & Flood Risk

Drainage & Flood Risk


The safe disposal of surface and foul water and management of flood risk are fundamental requirements for any new development. SYSTRA has substantial experience designing drainage systems and flood-risk management measures for a wide variety of development types and sizes, ranging from small residential or retail sites to large residential and commercial/industrial schemes.

Each site has its own specific requirements and issues. SYSTRA develops drainage and flood management solutions for each site to achieve our clients’ aims for the site and comply with current design standards and policies. We design conventional sewer systems alongside a range of SuDS methods to suit the site characteristics and the clients’ landscaping objectives.

The sequence of major floods in the UK since 1998 has driven changes in planning policies, legislative requirements and specific design standards. Drainage systems can no longer be considered separately to watercourses. We take an integrated approach considering both drainage strategy and flood risk to manage both in the context of the local water environment.

We provide our clients with cost-efficient drainage schemes to current design standards, which are capable of enhancing the positive environmental impact of a particular development.
