Condition assessment saves fire protection water line

A major hydroelectric maintenance facility site in Eastern Canada selected Echologics to determine whether their existing 60-year old cast iron (CI) potable water lines showed signs of degradation in order to plan for rehabilitation/replacement requirements and budgets. Echologics' field crew performed leak detection and condition assessment on over 1 mile of pipe in one day, with no impact to facility operations. The results were combined with other inputs, such as depth of installation (surface-to-crown), traffic loads (e.g., H-20, E-80), operating and surge pressures, and pipe bedding and backfill conditions to estimate the remaining service life. Fortunately, the old CI pipe was still in pristine condition and the electric utility was able to defer any need for pipe rehabilitation work, saving them hundreds of thousands of dollars.

Echoshore®-DX fixed leak detection system pinpoints leaks at condominium development

The homeowners association of a large condominium development in the northeastern US with a history of water main issues and leaks made a capital investment to help identify and fix problems before they become costly events for the owners. A 14-node EchoShore-DX system was installed on 6 to 10-inch ductile iron (DI) water mains on the site and implemented on a Mi.Net® network from Mueller Systems. In the first year of operation, the system identified six service leaks and one large water main leak. When asked about the EchoShore-DX system, the system operator said, “It alerts us to underground leaks as soon as they occur, resulting in less non-revenue water loss, less damage caused to surrounding areas and fewer customer complaints of sump pumps running constantly.”

Echologics innovation site adds PCCP pipe

The Phase II expansion of Echologics’ Innovation Site, the company’s research and training center in Walkerton, Ontario, is underway with the addition of prestressed concrete cylinder pipe (PCCP). The addition of PCCP will allow for development of technologies for condition assessment and continuous leak monitoring of PCCP pipe.

Our survey level condition assessment results for PCCP correlate well with internal electromagnetic survey results, enabling utilities to use ePulse technology for quickly surveying long distances of PCCP for identifying areas of distress for inspection by more intrusive and costly internal inspection tools. Some types of PCCP pipe, such as C303 bar-wrapped pipe, can leak before a significant rupture event, making continuous leak detection monitoring a very cost-effective method for reducing operating risk.

Opened in 2015, the Echologics Innovation Site replicates a fully functional water distribution network with more than 2,000 feet of buried pipe on site. Over the past two years, hundreds of utility staff and Echologics field technicians have participated in research and training at the facility.

Condition assessment of a water main near a busy rail line

A water utility in Pennsylvania selected Echologics to handle a complex project involving a 30-inch cast iron (CI) water main running parallel with and 10 feet from a busy freight train line. The main was installed in 1906 at the base of a berm carrying the rail line and exposed sections display surface corrosion. A leak or burst could severely impact rail operations and safety, and the main is non-redundant.

The portability of the Echologics condition assessment system was an advantage for the field crew as the remote location meant they had to carry the required equipment to each test point on the 3,100 feet of water main. The crew had to work around the train schedules to capture high quality acoustic signals in the time intervals between trains. The condition assessment results revealed several sections of the pipe with a high percentage of wall loss. The utility will use this information to better understand operating risk, and plan for any rehabilitation needs.

Condition assessment helps optimize pipe lining program

A large college town in Delaware, plagued by an increasing number of water main breaks, employed ePULSE acoustic condition assessment technology to help determine whether its aging pipes were suitable for lining rather than replacement. Lining was their preferred path, if possible, because of the reduced cost and minimal customer disruption versus replacement. The project assessed 12,400 feet of 6- to 12-inch CI and steel pipe in critical locations under major roads, railroad tracks, and rivers, along with representative neighborhood locations. The tests revealed that much of the pipe exhibited too much structural degradation to be suitable for non-structural lining. The utility was surprised to find a street where one pipe segment had about 60% loss but the next two segments had no measurable loss, indicating a change from unlined pipe to lined pipe mid-block, which was not indicated in the master plan.

AC water main inspection at old military site reveals poor condition

Echologics recently surveyed the site of a decommissioned Air Force base built in the 1950s and that now serves as a civilian airport, industrial area and housing complex for a city in New York. Approximately two miles of 8-inch AC pipe were inspected to proactively identify structural deficiencies, help plan replacement or rehabilitation, and identify any existing leaks. Key results from the ePULSE condition assessment found 16 of 22 segments of AC pipe were in poor condition with more than 30% average loss of wall thickness.

Pipe condition validated near previous main break locations

A valve closure in a Tennessee city caused a pressure transient event that resulted in four simultaneous water main breaks last year. To help prevent future problems, the water utility launched a proactive program to measure the average pipe wall thickness and to search for leaks in its 24” transmission main system. Echologics came on board, and our field engineers quickly completed an acoustic condition assessment using Echologics’ ePULSE technology. Our assessment was performed without interrupting water service and with minimal supervision from utility staff. We found 11% of the total pipe length in poor condition, and the remaining segments in moderate and good condition. The segments that were determined to be in poor condition were located near the previous leaks. These inspection results helped justify the cost of replacing just the pipe segments that were found to be in poor condition with no further cost or filed crew efforts for the pipe segments in good condition.

EchoShore®-TX monitors transmission main for saddle failures

A multi-node EchoShore-TX leak monitoring network has been commissioned for a critical 54-inch ductile iron (DI) transmission main in Georgia. This particular main is vital because it operates under high pressure to feed several surrounding water districts. Due to the high operating pressure and numerous air release valves along the line, the water company wanted an early warning system as an alert to potential issues with the water main, which runs through remote areas. The early warning will allow quick response to minimize damage and water loss. The initial deployment covers 6,000 feet with an opportunity to expand the coverage area in the future. During the client’s evaluation of the technology, the EchoShore-TX system positively identified and reported a simulated leak more than two miles from the closest node!

Water loss reduction efforts come up big

After outfitting several hundred fire hydrants with the EchoShore®-DX technology nodes for leak detection, utility staff in the first few months were able to quickly locate nearly a dozen leaks in their distribution system. As an unintended bonus, the advanced acoustic sensors were able to identify an acoustic anomaly through a 12” T-connection off of a 36-inch transmission main. It was confirmed as a large leak on the transmission main. The transmission main was several feet away from the monitored 12-inch line, and was not connected to the distribution main in the vicinity of the leak. This new leak detection monitoring platform is enabling the utility to reduce water loss, and to optimize their approach to leak detection and repairs.
