Sewer and water maps

Where known, the map identifies:

  • The location of public sewer
  • The location of water mains in our water supply area
  • Size and material of the sewer pipe.

Service pipes (property connections) are the responsibility of the property owner and will not be shown on sewer or water maps.

The map may not reflect the changes caused by the Water Industry (Schemes for Adoption of Private Sewers) Regulations 2011.
