Flooding and drainage

Learn about flooding and drainage responsibilities and how they affect local communities.

Public surface water sewers

These drainage systems manage rainwater that runs off:

  • Hard surfaces such as car parks, industrial sites, and public spaces
  • Roofs of buildings

Responsibility for these systems lies with the sewerage undertaker, usually your local water company.

Public surface water sewers are shown on the map of public sewers held by the sewerage undertaker.
