What is drain mapping?
Drain mapping creates a map of the layout of a sewer or drainage system of a specific area or property.
Why use drain mapping ?
Drain mapping is a used for both our private and commercial clients to gain information about the condition of their drainage system, and to establish where boundaries lie. This means they can discover who’s responsible for the sewage, drains & pipes ahead of starting building work.
Drain mapping is sometimes required by a property surveyor, as part of a drain survey, when buying a home and applying for a mortgage. Knowing how a drainage system is laid out can make finding faults easier, and repair work more effective.
Drain mapping techniques
Water Flushing
Running a tap or pouring water down the drain or even flushing a toilet can be easily used to see where water is flowing nearby and how drain pipes are connected.
As an advanced and more accurate method, a non-stain dye can be added to the water to identify its flow.
Testing the Water
By analysing of the type of water passing through the system eg if it’s sewage, waste or clearer looking water can help establish where the water originates from.
Dye Testing
Similar to ‘water flow tracing’ above, but a more comprehensive procedure as different water flows can be analysed by using different coloured dyes to colour the water thus making it easy to follow its flow.
CCTV
For getting the most accurate drain mapping information a special CCTV camera is pushed through the drains recording video footage and images pictures. High quality footage will show faults in the drainage system which can be recorded and provided as a conclusive report.
