Our Drainage CCTV units are able to survey lines from 100mmø to 1450mmø. With the ability to change the set-up of the camera, we can tailor the unit to maximise the visibility and quality of the survey being undertaken. The cameras also come with 270m of cable, allowing us to travel 540m from one access point. The crawler also comes with a pan and tilt camera head, along with a 10x optical zoom lens, meaning that we are able to identify the smallest of defects and to perform in-depth visual inspections.
All of our CCTV units have fully integrated offices where the engineers can complete coding as data is captured on site, and any structural issues can be sent to the main client as they are captured throughout the shift. Survey reports are coded using the latest Wincan software and can be sent electrically or in a hard copy format. Our surveyors are trained to a minimum OS19X of Pipe Sewer Condition Classification. All reports are produced in accordance with the WRc Manual of Sewer Classification.
Sewer mapping is the process of collecting information on existing sewer and drainage systems. This information is critical to design engineers who may be looking to upgrade existing systems, solve flooding problems or diverting existing watercourses. The data collected can then be used to build hydraulic models which are able to simulate the flow rate, storage capacity and discharge of existing systems.
