What is CON29DW?

The official CON29DW Drainage and Water Enquiry offers homebuyers complete peace of mind by identifying all the risks that a property may face in relation to the ownership and location of sewers and water mains.

Our search has helped prospective homeowners avoid thousands of pounds in unexpected maintenance bills and uncovered problems that had the potential to dramatically reduce property values.

Each CON29DW search includes the follow ing key information about property and land, helping homebuyers make a more informed choice about a property purchase.

  • Details of water and wastewater services at the property ? not all properties are connected to the public system
  • The location of public water mains and sewers in the area ? important if an extension is planned
  • The existence of any agreements or consents that may affect the enjoyment of the property
  • Information on the risk of internal flooding (e.g. from overloaded nearby public sewers)
  • An analysis of the risk of receiving low water pressure, together with possible remedial measures
  • The location of nearby sewage works - to help determine if odour or noise may be a problem
  • An assessment of water quality.

What information will the search provide?

  • Detailed information taken from Independent Water Networks technical and asset database.
  • Coloured location plan, showing water mains, public foul and surface water sewers currently on record in proximity to the property.
