We will work safely or not at all


Our approachHow we work in the Water Sector

The UK’s water network infrastructure requires constant modifications, upgrades and renewals to meet modern environmental performance standards, whilst operating under financial and regulatory pressure to minimise and reduce costs. With nearly 30 years of experience in the Water sector, we have the knowledge and expertise to capture the data unique water infrastructure that enables detailed designs for modern projects.

Industry Challenges

  • Historic record drawings are often out of date and only available in paper format
  • Many water treatment sites are congested with aging interconnected machinery and utilities that are unsafe and difficult to survey
  • Modern environmental design standards and BIM modelling techniques require a high level of detailed information to enable accurate and cost efficient designs to be created

40Seven Solution

  • We use the latest available technologies to capture underground utility locations accurately and efficiently
  • Above ground data is collected using advanced topographical techniques such as Laser Scanners and Aerial Drones
  • Data is proved to our clients in their preferred formats, including AutoCAD Civils, Revit and raw Point Clouds

Client SuccessWater services for Thames Water


Thames Water required surveys of their East Hyde Sewage Treatment Works.

Water treatment work sites require continual programme of maintenance and upgrade to ensure they continue to operate in a safe and effective way. There are plans to renew the processes and modernise the buildings and structure at East Hyde that required detailed and accurate information to inform the scheme design.

The complexity of the site and the level of detail requested by the designers required a multi level approach from our survey team. We employed a combination of traditional surveying using Total Stations, with the latest Faro Laser Scanners to capture the intricate detail of the machinery and site processes, including pipework, weirs, invert levels and coping levels so that the whole site could be accurately modelled in 3D.

A huge amount of data was captured to produce the Point Cloud, with over 63 million data points being collected from a total of 1,475 laser scan positions, gathered using two Faro S150 Scanners.

The resulting Pont Cloud dataset was then modelled to LOD300 using AutoCAD Revit to produce a highly detailed 3D BIM that the designers could then use to redesign the structures and processes. And now that the model has been created, it can be updated and added to easily once the new design elements have been constructed, creating a lasting record of the site for potential future works.
