Sewer and Drain Mapping Charting Survey 

It is important to know exactly where the drains and sewers are and who they belong to because sometimes local water authority drainage systems such as sewers, pipes, culverts, and surface water can often be found running through a property or under the private gardens. You MUST inspect your drainage infrastructure system before any building work can take place.

One that allows architects, builders & surveyors, residential property owners to determine whether a ‘build over’ agreement is required or not. We have been providing drain mapping services since 1984. It’s easy to see why we have become the first choice drain mapping & charting company in this field because we can accurately pinpoint any sewer or drainage pipework in and around London and Hertfordshire.

We have invested in the latest state of the art CCTV camera technology and crawler cam tracking units to carry out survey on pipework diameter from 100mm up to 4000mm pipework.


What Is Drain Mapping?

Drain Mapping is the process of tracing underground drains and locating existing underground drain lines, finding out where they go and plotting the information onto a site plan; the method used to gather this information can range from sonar tracing to GPS location, water/dye tests to laser profiling to a topographical survey – our drain 247 engineers are capable of carrying all works out quickly and efficiently.


In-House AutoCAD Team

Our In house team and external engineers have the capability to map and create a new AutoCAD drainage plan or to transfer drainage & sewer data onto a existing domestic or commercial AutoCAD map. The accuracy of this data is crucially important for architects and developers, and to meet this level of quality.


What Is Sonar Tracing?

sonar drain tracing is a method of drain mapping surveys and locates your drainage pipework; this technique relies heavily on sending out a signal from a Sonde transmitter that’s been integrated into our CCTV camera heads the signal is then sent back up and picked up by the drain tracing sonde receiver the engineer is using above ground. The engineer is then able to pinpoint the depth and location of the pipework, although sometimes the signal can become distorted due to interference from other utility services cables.


What Is GPS Mapping?

GPS mapping is a type of drain mapping, drain charting and drain & tracing underground drains services that integrate GPS locations with a sonar drain tracing. The contractor will use the utility drain tracing sonde and GPS tracer to be able to obtain the longitude and latitude reading. the data will then be transferred to the mapping service. The benefit of this is to allow for approx. location of the pipework to be obtained in accordance with the drain tracing sonde equipment manufacturers guidelines.
