What is a drainage district

What is a drainage district?

Drainage districts are typically found in low-Iying land where boundaries are determined by physical, not, political attributes. Districts vary in nature and size, from the mainly agricultural (such as Conwy, Llanfrothen and Towyn) to the semi-urban (such as the Gwent Levels).

Flood risks 

Drainage districts are at risk from various sources of flooding. Without flood risk and water level management, drainage districts would be unsuitable to live in and would not protect and provide for the variety of agricultural land, utilities and transport networks that have developed within their boundaries.
