Flood Risk Assessment and Surface Water Management Strategy, Thurleigh, Bedfordshire
Jun 10, 2013

RAB Consultants have recently completed a Flood Risk Assessment and outlined a surface water management strategy for a proposed large waste recycling facility near Bedford.  The planned facility will recycle surface water during the composting process.  It is a requirement of the Environment Agency that any water used in composting process must not enter a natural water body, e.g. groundwater, surface water drain/river.

The assessment involved the following:

* A site visit to assess flood risk at the site;

* Use of Microdrainage WinDes 2013.1 to calculate greenfield runoff rates at the site, surface water runoff and volume for a 100 year storm event including 30% for climate change, and post-development runoff and volume at the site;

* Preparation of a flood risk assessment report in accordance with the National Planning Policy Framework;

* Desk based assessment of suitable SuDS techniques using local geological records, * Environment Agency guidance and client consultation.

The report concluded that two lagoons would be required: an oversized lagoon for the storage and recycling of water for reuse on site as part of a sealed system; the other lagoon would act as an infiltration pond for the part of the site used for cleaner processes.
