Our Hot Topic - Sustainable Drainage Rain falling on buildings and hard surfaces needs to be drained effectively to prevent localised flooding. The traditional method of dealing with surface water has been to pipe it away from developments and discharge it into the sewerage system or nearby watercourses. This has implications for water quality and ecology. Sustainable drainage takes an alternative approach by using systems that allow rainfall to soak into the ground where possible, or by delaying discharges so the sewers and watercourses don’t become overburdened. The concepts of ‘source control’ and sustainable drainage are being heavily promoted by the Environment Agency and planners. By applying suitable solutions, SUDs can: • Minimise pollution Sustainable Drainage schemes require planning and design expertise. Surface water drainage needs to be controlled and integrated with the development’s environment. Waldeck Associates regularly consults on sustainable drainage schemes. We can provide designs that are developed from a review of the existing hydrological and hydrogeological situation and environmental impact assessments. We offer clean and comprehensive drainage schemes that are easily understood by site contractors and are simple to maintain.

Sustainable drainage is becoming an increasingly topical issue as Britain suffers increasingly from drought and floods. It is predicted that climate change will result in increased rainfall in the UK as well as an increase in the frequency of intense rainfall events. This is likely to exacerbate flooding problems.
