What makes the CON29DW products essential?

This illustration sets out in a diagram how both the CON29DW Residential and CON29DW Commercial are created. They draw on complex comprehensive data that is analysed by specialists during preparation.

Each report goes through various quality and review stages before being delivered to the conveyancer, giving confidence to property purchasers and their advisers.

Here are the stages of process:

  1. A customer’s enquiry is received
  2. First of all the property address is checked that it is on the records
  3. Once that is confirmed the process to gather all the information needed for a Drainage and Water Search starts. This requires drawing on multiple data sources.
    • For the residential searches this requires data on the following areas: Billing, Connection, Water assets, Sewerage assets, Water pressure, Sewer flooding history, Water hardness, Build over agreements, Asset adoption information
    • For the commercial searches this requires data on the following areas: Connection, Water assets, Sewerage assets, Trade effluent, Water pressure, Sewer flooding history, Wayleaves/Easements, Water hardness, Build over agreements, Asset adoption information
  4. Once the data has been collected and analysed this may raise queries and these need to be checked.
  5. The report is then prepared.
  6. Final quality checks are made.
  7. The final report is then released to the conveyancer.
