What do we do?

We are a body which work alongside the Environment Agency and your local authority, to maintain the integrity of our local waterways and land drainage of the surrounding areas.  Our expenses for this service are collected through drainage rates and special levies.

There are two Internal Drainage Boards associated with the River Medway:

…dealing with upland water and fluvial flooding

…dealing with lowland water and mainly tidal flooding
