One of the main advantages of a CCTV drain survey is that it’s minimally invasive. Because the camera equipment is inserted directly into existing access points—such as manholes, external drain covers, or internal rodding points—there’s often no need to excavate or dig up large sections of your property. Engineers can conduct the survey relatively quickly, depending on the length and complexity of your drain network. You can usually continue with daily routines, and businesses can often remain open, as the process typically generates little noise or disruption. In certain cases, light jetting or rodding may be needed beforehand to clear away debris and ensure the camera can pass through. However, this too is generally straightforward. Overall, a CCTV drain survey is a convenient diagnostic tool that offers thorough insights into your drainage health without the mess, noise, or extended downtime that more invasive methods might cause.
