What the survey records.
Manhole, connectivity and condition surveys so inverts, levels and routes are known before the excavator arrives on site.
Condition
Pipe runs inspected by CCTV so cracks, displacement, blockages and defects are on record before works start.
Connectivity
Which manholes, gullies and pipes connect to which, so the drainage layout on your drawings matches what is in the ground.
Invert levels
Levels taken at manholes and chambers so falls, depths and routes can be designed against real numbers.
How the survey runs.
A named surveyor, a programme before mobilisation, and a report that says plainly what was found and how sure we are.
- 01Surface
Access & records
We review any drainage records, agree access to manholes and chambers, and plan runs around your site.
- 02Below ground
CCTV & level survey
Runs are inspected by camera while covers, inverts and levels are surveyed and tied to the site control network.
- 03Delivery
Plan & report
A drainage plan with the condition findings, connectivity and levels, ready for your design team.
Watch a CCTV drainage survey, run by run.
A camera crawler travels the pipe from manhole to manhole while levels are taken. Defects and connections are logged as they appear, then drawn on your drainage plan.

Before you book.
If your question is not here, call and speak to a surveyor — not a call handler.
01Can drainage be surveyed together with other utilities?
Yes. Combining drainage with PAS 128 or GPR work means everything arrives on one drawing register.
02What is recorded at each manhole?
Cover and invert levels, pipe connections and the condition of what can be seen, tied to the site control network.
03What should I tell you before we start?
Anything known about blockages, access restrictions or live flows, plus the planned works so we can focus on the pipes that matter.
