Specialist CCTV Drain Surveys for Sensitive Environments
On any major construction project, understanding the condition of the drainage system is essential. This is especially true for sensitive environments like the Animal and Plant Health Agency (APHA), a government body that protects the nation’s biosecurity.
We were asked by Harrington Builders plc to perform a detailed CCTV survey and deep clean of the newly installed drainage network on site. Our aim was to identify any potential issues, map the system accurately, and provide a clear report.
For the Drainflow team, it was an opportunity to apply our two decades of specialist experience to ensure the long-term resilience of the site’s essential infrastructure.
Quality Assurance – Verifying New Drainage
If you’re working on a busy construction site, it’s often what you can’t see that can present the biggest risk. Even with the best installation practices, newly laid pipework can end up being impacted by construction debris, displaced joints, or unforeseen defects.
Which is why a CCTV survey is such a critical quality assurance step that protects contractors from costly remedial works and future liability.
Our Approach to Site Verification
Our CCTV drain surveys are designed to be thorough and non-disruptive. First, we use our high-pressure van-mounted drain jetting hoses to flush the new pipework, ensuring it’s free from any residual debris or sediment that could obscure the camera’s view.
Once the pipes are clear, our CCTV crawler camera is sent down to survey the drains. This remote-controlled unit travels through the pipe, and its pan-and-tilt, self-levelling camera head allows our technician to inspect every inch of the pipe wall and each joint connection in detail. The findings are recorded and delivered in a report, providing a permanent record of the condition of drains.
Applying the Same Rigour at a Landmark Location
Our commitment to quality assurance of course, extends across all our projects. Harrington Builders asked us for similar CCTV survey and cleaning services at a major new development near the Wembley Stadium.

On a large site like this, verifying the integrity of extensive new drainage networks is essential to prevent future problems. Our detailed survey provided Harrington Builders with the confidence and documented proof that all below-ground drainage was installed correctly and free from construction debris before handover.
