Case Studies
RFTC for Municipal Applications
Metropolitan Water District of Southern California (MWD)
The Metropolitan Water District of Southern California (MWD) is a consortium of 26 cities and water districts that provide drinking water to nearly 17 million people. PPIC has provided MWD with an accurate evaluation of the PCP within its system by using its Remote Field Transformer Coupling (RFTC) technology.
Dallas Water Utilities (DWU)
The 72” Simpson Stuart Supply Main, owned and operated by City of Dallas, Dallas Water Utilities (DWU) is a critical pipeline that provides treated water to the southern part of Dallas and Dallas Water Utilities southern customer’s. PPIC conducted an inspection of the line with an improved PipeCrawler platform that could accommodate for the large diameter without the need to fully dewater.
El Paso Water Utilities (EPWU)
To serve the needs of this burgeoning city, El Paso Water Utilities (EPWU) operates over 2,200 miles of water transmission mains. PPIC conducted a non-destructive evaluation of two areas of the Roseway Water Transmission Main using its PipeCrawler inspection tool.
Halifax Water
Halifax Water is the municipal water utility for the Halifax Regional Municipality in Nova Scotia, Canada and provides utility services to about 325,000 residents. Halifax Water selected PipeDiver™ to carry out a pipeline condition assessment without dewatering or shutdown.
Denver Water
Denver Water serves a population in excess of 1.1 million people in the Metro Denver area and operates over 2,600 miles of water transmission mains. To date, Denver Water Utility has inspected 23 miles of PCP using the patented Remote Field Transformer Coupling (RFTC) technology.
Extendable Mast PipeCrawler™ - Illinois
In 2006, PPIC performed a challenging condition assessment on a four mile section of a 36-inch PCCP line for a large water utility in Illinois. This particular pipe section could not be dewatered and, furthermore, contained seven reducers that changed the pipeline diameter from 36-inches to 24-inches.
The Great Man Made River Project
The world’s largest single PCP project is North Africa’s Great Man Made River (GMRA). As a result of the data provided by the RFTC inspection system, GMRA has replaced over 7,000 individual pipes, dramatically improving the integrity of the asset.
AET for Municipal Applications
El Paso Water Utilities (EPWU)
In 2000, EPWU implemented a water conservation strategy which emphasized promoting water conservation, increasing the use of Rio Grande water, and implementing the reuse of reclaimed water. Determined to lead the way in water conservation, EPWU went one step further and contracted with PPIC to assess the condition of portions of its 48" Prestressed Concrete Cylinder Pipe (PCCP) pipelines.
Sahara® for Municipal Applications
Philadelphia Water Department
The Philadelphia Water Department (PWD) has focused aggressively on water loss control. In 2007 PWD began to employ the Sahara® Leak Location System on its large diameter water transmission mains.
San Francisco Public Utilities Commission
San Francisco Public Utilities Commission serves 29 wholesale water agencies and delivers approximately 260 million gallons of water per day to its customers through a 280-mile pipeline network. In October 2004, SFPUC contracted with PPIC to inspect pipelines using the Sahara® leak location system.
Dallas Water Utilities
Due to population growth in the Dallas-Ft. Worth Metroplex, DALW is bringing additional water sources on-line. Normally used as a condition assessment tool that identifies leaks in in-service pipelines of any material construction type, Sahara® was adapted to pinpoint the leaks in uncommissioned pipelines.
North Texas Municipal Water District
NTMWD operates over 375 miles of water transmission pipelines within its 1,600 square mile service area and serves 1.3 million people. In 2005 PPIC inspected 984 feet of a 42" main using Sahara® Leak Detection Technology.
Muskegon County
After a pipeline failure in 2007, Muskegon undertook a condition assessment program to determine whether rehabilitation of their pipeline was a preferable option to replacement.
Transient Pressure Monitoring
Sault Ste. Marie
In October 2008, the City of Sault Ste. Marie conducted a condition assessment program on two of its critical wastewater force mains.
Water Wholesalers
Tarrant Regional Water District
The Tarrant Regional Water District (TRWD) is a raw water supplier that serves ten counties in north central Texas. TRWD conducted a condition assessment of its pipeline using the Remote Field Transformer Coupling (RFTC) pipeline evaluation system.
