Learn how CCTV drain inspections work, step-by-step, including their benefits and common issues detected in stormwater and sewer systems.

CCTV drain inspections are a cornerstone of modern asset management. From small blockages to major pipe defects, knowing the exact condition of your underground infrastructure allows for precise, proactive maintenance. In this guide, we’ll walk you through the entire CCTV inspection process—from deploying the camera to analyzing the data—and explain why it’s essential for efficient drainage management.

What is a CCTV Drain Inspection?

A CCTV (Closed-Circuit Television) drain inspection uses specialized cameras to visually inspect the interior of drainage pipes and sewer networks. Unlike manual inspection, CCTV allows for:

· Accurate diagnosis of blockages and damage

· Minimal disruption to surface operations

· Efficient data collection for maintenance planning

Step-by-Step CCTV Inspection Process

Preparation

Inspect the site and identify the sections of pipe to survey
Ensure access points are clear and safe

Camera Deployment

A waterproof, flexible camera is fed into the drain
Live feed allows operators to identify issues in real-time

Data Recording

Footage is recorded digitally
Operators can tag defects, measure pipe dimensions, and note potential problem areas

Analysis

Footage is reviewed to identify blockages, cracks, joint misalignment, and root intrusion
Detailed reports are generated for maintenance or repair planning

Common Issues Detected by CCTV Inspections

· Blockages from debris, grease, or roots

· Structural defects like cracks, collapses, or displaced joints

· Corrosion or pipe erosion

· Stormwater inflow and infiltration

Benefits of CCTV Drain Inspections

· Proactive Maintenance: Prevents costly emergency repairs

· Efficiency: Saves time compared to manual inspections

· Accuracy: Provides precise visual data for decision-making

· Documentation: Creates a digital record for regulatory compliance and future reference
