As drain mapping contractors; Drain 247 offer a full range of drain mapping services for architects, builders & surveyors, residential property owners, commercial property owners, building developers & more.

Our drain mapping service is 99.7% accurate and is an ideal solution that plays a very important role in any building work. This is because your drainage infrastructure system MUST be inspected before any building work can take place.

Many residential property owners, commercial property owners, building developers do not have any drainage plan of where they drains and sewer pipes are within the property boundary. 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.

Drain 247 has invested in the latest mapping technology equipment which has a tolerance of 0.3% of the position and depth of any drainage pipework. (For example, 0.3% of 1.0meter is 3mm). This enables Drain 247 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 diameter 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 plan 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 For more information on the price please contact our office on our freephone number 0800 612 8038  and our staff will be happy to offer you a free quotation.

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.
