3D Chamber Profiling & Manhole Surveys
Chamber profiling is the process of accurately measuring the depth, diameter, and flow direction of pipes within a chamber or manhole, including sewer systems. This essential service provides a clear understanding of your drainage system’s layout, enabling precise planning for repairs, maintenance, and future works.
At Subscan QWM, we use state-of-the-art Cleverscan technology and advanced software to produce detailed 2D and 3D reports. These reports include high-resolution visuals of the manhole chamber’s internal structure, providing valuable insights for engineers, designers, and surveyors.
Optimise your drainage system with confidence through our expert chamber profiling service. Delivered by one of the UK’s most qualified teams of drainage specialists, Subscan QWM offers comprehensive nationwide coverage — ensuring fast, reliable solutions that minimise disruption and keep your system running smoothly.
Cleverscan in Action: Manhole Inspection Made Simple
Cleverscan is an advanced manhole inspection system built for detailed, high-resolution surveys without the need for confined space entry. Each Cleverscan unit is equipped with five cameras and a precision laser scanner, delivering a complete visual and dimensional record of the chamber — highlighting defects, infiltration sources, and any previously unmapped features.
Our technology captures a full 360° flat scan and a dense point cloud model of the manhole interior, providing exceptional clarity and accuracy. The resulting data can be seamlessly integrated into CAD or 3D modelling software for further analysis.
This efficient, non-entry method enables engineers and designers to make fast, informed decisions, eliminating the delays and safety risks of traditional manual inspections.

At Subscan, we combine cutting-edge technology with industry expertise to deliver high-quality engineering surveys across multiple sectors. Our engineers uphold the highest standards to ensure every project benefits from accurate, dependable results.
Case Study
Client:
Rail Client
Project type:
Cleverscan, Chamber Inspection
Location:
North West Region
Overview
Survey Engineers in the North West utilised CleverScan technology to safely inspect a drainage chamber located beside a live railway — achieving a full 360° visual capture and 3D chamber map without requiring personnel entry into the confined space.
Survey Engineers in the North West deployed CleverScan to capture 360° imagery and produce a 3D visual map of a chamber — all without a single person entering the confined space.
Given the chamber’s location beside a live railway, no-man entry was permitted. CleverScan proved to be the only suitable and safe solution for this critical inspection.
During the survey, the team identified a collapse within the drainage system, believed to have been caused by nearby construction works — a stark reminder of how vital planning, oversight, and accurate data are when working around critical infrastructure.
