Pure Technologies Announces $4 Million Contract Extension
August 30, 2011Pure Technologies Ltd., (TSX: PUR) has announced that it has been awarded a contract extension worth approximately $4 million to supply monitoring and technical support to the San Diego County Water Authority (SDCWA).
This contract builds on the work that initially commenced in 2005 when Pure was retained by the SDCWA to install a temporary acoustic monitoring system in sections of the Water Authority’s prestressed concrete cylinder pipe (PCCP). The success of the initial monitoring program led to an expanded program in 2006 with the installation of the newly developed acoustic fiber-optic (AFO) monitoring system. Today, there are seven AFO systems in place monitoring just more than 50 miles of PCCP.
The SDCWA has more than 250 miles of critical large diameter pipelines that provide up to 95 percent of the water to the San Diego County’s population of 3 million people. In order to provide a safe and reliable supply of water to San Diego County, the Water Authority implemented the Aqueduct Protection Program (APP) in 1992. Part of the program consists of developing and researching new noninvasive/non-destructive inspection procedures to determine the condition of existing PCCP; AFO is a vital part of this proactive condition assessment program.
The SDCWA is considered an industry leader in proactive management of PCCP pipelines; the rapid acceptance and deployment of the AFO technology has provided the Water Authority with the ability to track the deterioration rate of the pipelines in close to real time. Furthermore, the information provided by the AFO system coupled with previous inspection data has allowed the SDCWA an improved cost-effective approach to managing their PCCP inventory.
