Further information


Every development will be unique in delivering SuDS, and so will the SuDS that are incorporated into them. A major benefit of SuDS is that they’re adaptable to different site constraints and geological areas. Where a site falls in an Internal Drainage Board area we strongly recommend pre application discussions so as to understand their catchment and constraints.
Current Situation

During September 2014, the Government held a new consultation to explore the proposal of delivering SuDS through the current planning application process. This alternative approach would see strengthening of the existing National Planning Policy Framework; giving local authorities a more robust system through which to instruct sustainable drainage on significant new developments.

As of April 6th 2015 this approach in delivering SuDS was implemented. To achieve SuDS as part of your development you should ensure you adhere to Defra’s Technical Standards. The Local Authority SuDS Officer Organisation, LASOO, has produced practice guidance in association with the HBF and the NFB (previously the HBA). You can also also find relevant Flood Risk FAQs on the Planning Practice Guidance website.
Typical SuDS Techniques

Below are a few examples of different SuDS techniques achieving a reduction in flood risk, improving water quality and bringing about biodiversity benefits:

Example of a swaleSoft landscaping
Landscape features, such as rain gardens, swales, ponds and wetlands, can be designed to collect and store runoff.
Green roof exampleGreen Roofs
A roof with plants growing on its surface, which contributes to local biodiversity. The vegetated surface provides a degree of retention, attenuation and treatment of rainwater, and promotes evapotranspiration.Further information available from susdrain
Rain Water HarvestingRainwater Harvesting
This refers to the capture and storage of rain water which is then used in households and businesses for day to day activities. These can vary between tanked systems which provide water for flushing toilets and water butts for watering plants in the garden. The reuse of rainwater reduces the demand on clean water supplies.Further information available from susdrain
Permeable PavingPermeable Paving
Rainwater filters through permeable paving where it is stored before soaking into the ground or entering surface water systems.Further information available from susdrain

Example of Permeable Paving

Take a look at our sustainable drainage system (SuDS) scheme utilising permeable paving being demonstrated at Fleetwood Crescent in Peterborough:

Further information on the design and construction is available in our Fleetwood Crescent Report

Inclusion in Development

The council supports SuDS techniques being used on all new developments. It is also possible to incorporate SuDS into existing buildings.
