Louisville Water Works Museum Pipediver Tool

In March 2013, Louisville Water Company (LWC) will open its “WaterWorks Museum” located in its original pumping station built in 1860. The original pump station and water tower have stood on the banks of the Ohio River for over 150 years and act as a visual icon for the city. Both buildings are now National Historic Landmarks.

The museum will highlight LWC’s considerable archive of historic photographs, films and memorabilia and explore the company’s contributions to water delivery through its innovations in science, engineering and architecture. It will also feature hundreds of photographs, some dating back to 1860, handwritten minutes and customer notes, original architectural drawings, pieces of the original water mains, meters and tools.

Included in the exhibit will be a model of the PipeDiver® tool to commemorate a condition assessment project completed in 2011. The project focused on LWC’s proactive pipeline management approach that addressed deterioration in its Prestressed Concrete Cylinder Pipe (PCCP).

The PipeDiver tool is a free-swimming electromagnetic (EM) platform used to identify and quantify wire breaks in PCCP. The EM sensor collects a magnetic signature reading as the tool traverses the pipeline and identifies anomalies produced by wire breaks. The tool operates while the pipeline remains in service, allowing LWC to avoid shutting down service to assess the condition of its most critical pipelines.

PipeDiver Model

LWC inspects about 8 to 10 miles of PCCP annually. Typically, between 2 and 4 percent of LWC’s PCCP is found to have deterioration, while less than 1 percent needs to be addressed immediately. This is consistent with industry averages, meaning it is most cost-effective to complete condition assessment and address isolated problems before replacing large sections of pipe, which carries a huge cost.

Pure Technologies’ data from over 8,000 miles of pressure pipe condition assessment indicates that only a small percentage of pipes (less than 5 percent) are in need of repair and therefore have a significant remaining useful life. Condition assessment data also suggests that pipe distress is localized and a significant ROI can be achieved by locating and addressing isolated problems through structural inspection.

PipeDiver® – Free-Swimming Pipeline Inspection

Specifically designed for structural assessment of Prestressed Concrete Cylinder Pipe (PCCP) lines that are live or can’t be taken out of service due to a lack of redundancy or operational constraints.
