Foul and Surface Water Drainage

Where the housing is proposed the land is designated as Flood Zone 1 which has the lowest risk of flooding. Surface water from the development will be stored in tanked permeable paving across the Site. This water will be conveyed by swales across the centre of the Site, before being stored in below ground attenuation tanks at the Site’s western edge. The water will then be subject to a controlled release into the existing rhyne network.

Foul water water will be conveyed by sewer to a below ground package treatment plant, where the water will be cleaned before being discharged into the rhyne network.
