New CCTV tool inspects pressurized water mains
The Pressure Pipe Inspection Company Ltd. (PPIC) has introduced the industry’s first CCTV tool capable of inspecting up to 6,000 feet of an operating water main. The video capability is the latest tool to be added to the Sahara platform, which already includes leak and gas pocket detection.

The Sahara Video tool gives utilities the ability to see inside large diameter, pressurized water pipelines without costly shutdown or dewatering. The CCTV video tool can be used for a number of applications including:

  • Locating lost line valves;
  • Investigating unexplained flow conditions;
  • Locating debris and partial blockages;
  • Searching for illegal connections;
  • Locating and assessing tuberculation of all types;
  • Visually inspecting pipe walls and liners; and
  • Examining the condition of suspect valves.

Sahara Video is easily inserted into a live pipeline through a standard two-inch or larger tap. Tethered to the surface, the Sahara CCTV camera is gently pulled by the flow of the water transmitting real-time video data from inside the pipeline.

The first tethered tool designed for live inspection of large diameter water mains, the Sahara pipeline inspection platform is the most accurate technology available for detecting leaks, pockets of trapped gas, and other defects in large mains. Sahara is a critical component of condition assessment and water loss management programs for utilities around the world.

GL wins Pipelines Industries Guild Award
Antony Green, GL Vice President Water, accepts the Pipeline Industries Guild Award for GL's Burstfinder Technology.
The Pipeline Industries Guild (PIG) Award was given to Germanischer Lloyd (GL) for significant contribution to utility pipeline technology for their Burstfinder Technology at the 53rd annual awards ceremony in London.

"Burstfinder" is GL's leakage and demand location technique and is provided as a service to water utilities and leakage contractors to help identify "hotspots" of anomalies in water networks such as non revenue water, boundary breaches and possible burst locations.

The Burstfinder software has helped water utility companies with leakage detection and repair activities, resolution of problem networks and location of leakage, and other forms of unaccounted for water.
