Inspection and Locating

Putting Technology to Work Over the years the evolution and adaptability of electronic and digital camera technology has made the identification and evaluation of compromised plumbing and drain pipes and infrastructures a precision-driven and exacting science. CWW’s service van units are all equipped with snake CCTV video cameras and monitors complete with DVD recorders. CWW plumbing technicians are able to insert a small video camera deep into the pipe, record their findings, and provide the appropriate advice and recommendations for the right rehabilitation technique on-site.

Next-Generation Navigation CWW push snake cameras are also built to withstand rough environments; yet flexible enough to navigate through any series of sharps turns and bends, and successfully penetrate and enter small diameter pipes. Typically, CCTV analyses with push snake cameras are deployed in drains of up to 8” in diameter. CWW strategically deploys crawling cameras from its custom camera trucks for larger pipe diameters. CWW will also deploy additional types of locating devices that can pinpoint the exact location of drain pipes beneath flooring.

The Dye is Cast Dye testing is yet another investigative methodology used by CWW. CWW uses dye testing to locate the source of a connection to a drain or sewer. A camera is pushed into the main drain or clean-out, and a dye tablet is flushed into the system from a toilet. The bright coloured dye seeps into the drain and is visually captured by the push camera to confirm the location of the connection. Dye testing is also used to determine the existence of a separate storm and sanitary sewer exit.
