The Use of Untethered Acoustic Ball Technology To Locate Leaks in Pressurized Water Mains
Investor-owned & municipal utilities may experience catastrophic damage if it relies on Untethered Acoustic Ball technology to locate leaks. As shown below, the inspection of a 10,000-feet (3km) of 36-inch (913mm) diameter Prestressed Concrete Cylinder Pipe (PCCP), gave a clean-bill-of-health with ‘NO LEAKS’ using a leading vendor’s Untethered Acoustic Ball technology. Eighteen (18) months later, separate pipe ruptures occurred. Read more…
Large Florida Utility Saving Money through Innovation
After spending decades and millions of dollars rehabilitating sewer pipes across its service area, a large coastal utility embarked on a pilot pipe condition assessment program for 25,000 linear feet in areas prone to high unwanted infiltration rates. Read more…
Innovative Pipe Inspection Program Supports Meaningful I/I Reduction for a Large Florida Utility
One of the state’s largest water utility is facing significant challenges with excessive inflow and infiltration (I/I) in its gravity collection system, consisting of over 1,500 miles. Precipitation events often result in immediate flow responses within the collection network, at times up to 3 times the average daily flow rates. Read more…
North American Benchmark Study Comparing CCTV v. FELL Inspection on 322 Gravity Sewer Mains
Key Findings and the Executive Summary are presented for a first-of-its-kind 14-mile North American pipeline benchmark study, comparing Closed-Circuit Television (CCTV) inspection against Focused Electrode Leak Location (FELL) inspection results. Both inspection techniques were completed by the same national pipeline contractor. Read more…
