lower severn internal drainage board

Always thinking ahead...

The Lower Severn Internal Drainage Board (LSIDB) is an independent public body maintaining local watercourses and drainage.

What we do

Every single day we help the drainage of 21,000 hectares of land along the River Severn spanning Gloucestershire, South Gloucestershire, Herefordshire, Worcestershire, and Bristol City.

As our climate changes, managing water levels is vital. Low-lying areas can flood; drought is becoming more common. Both scenarios place agriculture, critical infrastructure, the built environment, and habitats at risk.

Explore our work

In all drainage districts, it’s vital that open drainage channels are regularly dredged, and vegetation controlled. In some districts, underground stormwater culverts need to be kept in good repair and maintained.

These essential works maintain the environment and conditions for local residents and businesses, ensuring full use of land that would otherwise be prone to flooding.
