CCTV Inspection and Locating

Remote Examination in Real Time CWW’s Closed-Circuit Television (CCTV) trucks are fully equipped with state-of-the-art “Pan & Tilt” (P&T) video camera equipment used for mainline sewer inspection. CWW CCTV trucks are also equipped with computer hardware/software to facilitate data acquisition. CWW on-site trained and qualified operators can inspect and evaluate the condition of the pipe via flat screen monitors on board while the images are being televised in real time through the evaluation standards specified by the customer, including: WRC, NAPPI, NASSCO, or CERIU. Defects and general observations are indicated on the video as entered by CWW operators. A digitally-formatted full-scale inspection report is then generated based on the operator’s observations and subsequently reviewed by CWW report-generating technicians located in CWW’s headquarters.

A Reliable High Tech Solution CWW is proud to be among the few Canadian companies offering Lateral and Mainline Probing (LAMP). LAMP is an essential inspection tool used for the identification of compromising sewer pipe infiltration and inflow, the accumulation of solids, root infiltration, pipe defects, and the structural condition of lateral services and mainline sewers. Self-propelled, LAMP provides a one-pass P&T inspection of mainline sewer pipe with diameters of 6″ and 24″, with simultaneous inspection of the adjacent lateral services up to 80’. Equipped with two high resolution cameras, the LAMP picture-in-picture feature allows CWW’s operator to monitor the P&T inspection of the mainline pipe and launch a camera from the mainline to inspect the adjacent lateral service. LAMP is also used in the horizontal boring industry for precise locating of lateral services, which avoids costly damages to the existing sewer infrastructure during the boring process. LAMP is also used to verify the quality of rehabilitation processes such as lateral and mainline relining and spot repair. CWW’s LAMP system can be mounted in a truck or retrofitted to most existing truck mounted CCTV systems.

Features and Benefits

Pan & Tilt and Lateral Inspection (LI) Cameras

• P&T inspection of mainline pipe with the simultaneous examination of lateral service
• P&T inspection of 6” through 30” diameter mainlines
• Lateral inspection of 2” through 6” pipe diameter services
• P&T and LI cameras feature the same dimensions: 1.5″ in diameter and 3.5″ in length
• Camera centering ball for the LI camera to maximize protection and passage
• LED lighting for P&T and LI cameras with a life expectancy rating of 5,000 hours
• Self-propelled camera launcher featuring both P&T camera and an LI cameras
• Low Lux Cameras are light sensitive to .3 lux at F1.2
• High Resolution Cameras provide sharp clarity and detail
• Optional Sonde and camera locating receiver

Lateral/Mainline Self-Propelled Camera Launcher (LAMP)

• Launcher is self-propelled with forward, freewheel, and powered reverse with a maximum forward speed of -60′ per minute
• Lateral camera launches, extends, and retracts at a maximum speed of 30′ per minute
• Displays mainline and lateral footage on screen and on video tape and (or) CD
• Launcher optically centers the camera in the pipe above most flow and debris lines
• Launcher contains variable weight extenders that increase weight (traction) and bottom clearance as the pipe diameter increases
• Launcher rotates to position the lateral camera for entry, monitored by P&T camera and picture-in- picture video display
• Robust 83′ combination push / video cable for lateral camera that is enclosed and protected by a stainless steel sheath
• The length of the launcher with P&T camera and lateral camera including connectors is less than 37″ in length

Time and Space CWW has a great deal of respect for LAMP technology, as LAMP allows CWW crews to commence the mainline sewer inspection from one manhole and inspect the entire mainline while at the same time inspecting all the laterals from the main pipe. LAMP also provides for the location of sewer laterals. While there is another available option to CCTV (gaining access to the lateral from inside the house), the inconveniences experienced far outweigh any potential benefits. Such a plan requires the untimely collection of homeowner contact information, attempting to reach the homeowner through a series of phone calls to establish an appointment at the homeowner’s convenience, and potentially entering private properties unannounced. Deploying LAMP eliminates every one of these inconveniences and the inherent prohibitive timelines associated with them.
