CCTV Drain Surveys
See exactly what’s going on inside your drains — before it becomes a bigger (and more expensive) problem.
At Treaty Drains, we use high-definition waterproof cameras to inspect your drainage system from the inside. Whether you’ve got a stubborn blockage, a recurring issue, or need to check underground drains before purchasing a property — our surveys give you clear answers fast.
What Is a CCTV Drain Survey?
A CCTV drain survey is a non-invasive inspection using a specialist camera that’s fed into your drain system. It provides a live HD video feed showing any internal problems — like cracks, blockages, root ingress, or collapsed sections — so we can identify and fix issues quickly and accurately.
Drain Locating (Sonar Tracking)
Not sure where your drain runs underground?
We use electronic locators to trace the exact location and depth of our camera head. This means we can pinpoint defects or buried pipework with precision — ideal for repairs, excavations, and mapping unknown drainage layouts.
