Sewer and water maps

Customers involved in either large-scale land purchases for commercial and residential property development or the possible extension of a home often need to know the location of public infrastructure.

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.

A4 and A3 sized maps are produced electronically; A1 and A0 sized maps are prepared on paper. All maps are returned within five to 10 working days once payment is received.

For orders requiring multiple plans, additional charges will apply. Please contact the LandSearch team for more information.

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