The District of Columbia Water and Sewer Authority (DC Water) has awarded Mississauga-based, Pure Technologies, through its wholly-owned subsidiary, Pure Technologies U.S. Inc., a contract worth up to US$10 million over five years for condition assessment of their major water and sewer pipelines.

Using its proprietary technologies and solutions, Pure will collect new pipeline inspection and condition data and work with DC Water’s asset management division to integrate this information into their existing data management systems. Pure will also provide data analysis and recommend pipeline rehabilitation options for large diameter water pipelines and major sewers in Washington, DC.

The new contract expands on prior work, conducted by Pure over the past 3 years, including pipeline condition assessment and helping to develop a pipeline risk prioritization and management program allowing DC Water to cost effectively manage their critical pipelines. Previous, collaborative efforts also include an analysis of DC Water’s large diameter water pipelines using machine learning techniques to determine probability and consequence of failure.

The District of Columbia Water and Sewer Authority is an industry leading, multi-jurisdictional regional utility that provides a reliable water transmission system to over 681,000 residents, 1.7 million annual visitors and 700,000 people employed within the City limits. In addition, DC Water is responsible for providing a reliable sewage collection system to more than 2 million people in the Washington, DC, Metropolitan area.

Pure Technologies has been in operation since 1993 when launched its acoustic sensors to detect physical changes in building and bridge structures. In 1997 the company entered the water and wastewater market by adapting its SoundPrint technology to monitor large-diameter prestressed concrete pipelines.
