What is a CCTV Drainage Survey?
A CCTV drainage survey is an advanced, non-intrusive method of inspecting drainage systems using high-resolution cameras. These specially designed cameras allow engineers to identify issues such as blockages, cracks, collapsed pipes, and root intrusion without the need for excavation. This approach is cost-effective, accurate, and minimises disruption.
- CCTV surveys are essential for:
- Preventing costly repairs by detecting problems early
- Assessing system capacity for new developments or extensions
- Complying with building regulations and planning requirements
- Providing peace of mind for property owners and developers
- Asset connectivity tracing and plotting
