Case Studies

Great Man-Made River

With more than 4,000 km of mainly four-metre diameter prestressed concrete cylinder pipe (PCCP) in operation, the Great Man-Made River pipeline is the one of the largest water projects in the world.

Dallas Water Utilities - Condition Assessment

Since 2005, DWU has been interested in a condition assessment of the 72" Stuart Simpson line, a nearly 50 year old large-diameter PCCP main, but has faced a lot of challenges.

City of Rockville - Robotic Inspection

Pure Technologies (Pure) was contracted to provide a robotic inspection of a critical 24-inch prestressed concrete cylinder pipe (PCCP) transmission line for the for the City of Rockville’s Department of Public Works (DPW). The City’s single 10 mile-long transmission main system traverses from the Potomac River to the Rockville city limits before branching off into the distribution network.

Baltimore County - Sewer Force Main Assessment

As part of Baltimore County, Maryland’s Wastewater Force Main Asessment Program, Pure Technologies inspected the 54-inch Patapsco PCCP Force Main using the SmartBall® and PipeDiver® pipeline assessment tools.

Grand Forks Wasterwater Authority - Sewer Force Main Assessment

In late October 2008, the Grand Forks Wastewater Authority (Authority) located in Grand Forks; North Dakota initiated a project to conduct a condition assessment of an 8.8 mile 30- and 36-inch wastewater force main.

Petrobras - Leak Detection

Pure Technologies (Pure) has conducted two inspections of a 12-inch mutli-phase product pipeline in eastern Brazil, owned by Petrobras. Pure utilized its 10” Polyurethane coated SmartBall leak detection tool to detect a total of three simulated leaks during two separate runs on this pipeline.

Plains Midstream - Leak Detection

Pure Technologies (Pure) conducted several successful inspection simulations with Plains Midstream before the client progressed to a series of commercial inspections.

TransCanada Pipelines - Leak Detection

Pure Technologies completed a demonstration inspection of a portion of the Grande Prairie Mainline gas transmission pipeline for TransCanada Pipelines. The inspection was conducted as a trial of the capabilities of the SmartBall leak detection tool in gas pipelines.

Fred Hartman Bridge - Structural Monitoring

After the Fred Hartman Bridge was completed in 1995, large-amplitude vibrations of the cables were observed. Following comprehensive testing, TxDOT installed a SoundPrint® Acoustic Monitoring System to monitor any wire break activity occuring within the stays.

Waldo-Hancock Bridge - Structural Monitoring

In order to ensure the future safety of the bridge, Maine DOT commissioned Pure Technologies to install a SoundPrint® acoustic monitoring system to detect and locate any future wire breaks. The SoundPrint system utilized wireless sensors to monitor both main cables from anchorage to anchorage.
