In 2011, Interactive Pipe Inspection (IPI) completed inspection of more than 50,000 feet of 30- and 48-inch diameter sanitary sewer lines for King County, WA.

What sets the project apart from routine pipeline inspections is that the sewer lines were underwater in Lake Washington and Lake Sammamish.

A new spiral-wound pressure pipe has been introduced to the North American market for use in water and wastewater systems.

Closed circuit television (CCTV) inspections have become the standard method for inspecting the condition of the inside of underground pipe infrastructure, providing information about their condition and areas where deterioration and damage require pipes be repaired, rehabilitated or replaced. CCTV inspections also verify repairs are properly made and that new pipe has been correctly installed.
