The drain mapping service we offer provides an ideal solution in any building work. This is because your drainage infrastructure system MUST be inspected before any building work can take place as many residential property owners, commercial property owners, and building developers do not have any drainage plan of where the drains and sewer pipes are within the property boundary. Build over surveys are becoming more common nowadays for people building extensions.

Build over survey are becoming more common now a days for people building extensions. It is important to know exactly where the drains and sewers are and who they belong to. It is also important to note that 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.

Using this information, as well as the latest mapping equipment and technology, builders, surveyors and architects can determine whether a ‘build over’ agreement is needed. It’s easy to see why Drain 247 has become one of the leading contractors for drain mapping services in the UK.

Drain 247 chose to invest in the most innovative mapping technology equipment from the US giving mapping display in real-time signal information including location, direction, depth and trustworthiness.

The manufacturer confirms it’s the most accurate available and that dead spots, or nulls, are eliminated for greater speed and accuracy. This enables Drain 247’s experienced engineers to create high-quality drainage reports, drainage maps and full annotated site plans of sewers, culverts, riverbeds and wider drainage systems.

Also using our state of the art camera technology and crawler cam tracking units. Drain 247 can survey diameters from 100mm up to 4000mm pipework.

Our In-House AutoCAD Team

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

Our Drain Mapping, GPS Charting, Sewer Mapping, Sonar Tracing and Pipe Location cost is based on the level of investigation required. The cost of a standard terraced or semi-detached house would typically require 2 hours to survey and map the drainage system.

What Is Drain Mapping?

Drain Mapping is the process of 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.

Services include:

  • CCTV Drain Survey
  • Rat & Rodent Survey
  • Drain Mapping & Charting
  • Sonar Tracing & Pipe Location

What Is Sonar Tracing?

Sonar tracing is a method to map and locate 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 Sonde receiver the engineer is using above ground.

The engineer is then able to pinpoint the approximate 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 services that integrates GPS locations with a sonar trace. The drain napping contractor will use the utility GPS tracer to be able to obtain the longitude and latitude reading. This data will then be transferred to the mapping service. The benefit of this is to allow for the approx. location of the pipework to be obtained in accordance with the equipment manufacturers guidelines.
