2009 REHABILITATION PROJECT OF THE YEAR AWARD

Renewing Washington Suburban Sanitary Commission's Water Transmission System

Trenchless Technology, a leading industry publication, announced that one of Pure Technologies' projects has been selected as "2009 Rehabilitation Project of the Year".

The project entitled "Renewing WSSC's Water Transmission System" has been recognized for the use of innovative assessment and repair technologies to develop a cost-effective asset management program for a large-diameter prestressed concrete transmission pipeline system. The Washington Suburban Sanitary Commission ("WSSC"), its consultants and contractors have all been cited in the award. Serving nearly 2 million people in Montgomery and Prince George's counties in Maryland, WSSC is the eighth largest water and wastewater utility in the country, operating and maintaining nearly 5,500 miles of water main lines and more than 5,300 miles of sewer main lines.

AGING INFRASTRUCTURE SENDS BALTIMORE A MESSAGE

A 72-inch water main failed on September 18th leading to flooding of commercial and residential properties in Dundalk, MD, on the southeast side of Baltimore. The 72-inch main was installed in the 1970s and was manufactured by the Interpace corporation. The pipe failed under the shoulder of Broenig highway and flooded more than 100 homes and several dozen cars in the area. All major television and newspaper organizations covered the failure.
Pure Technologies and Openaka recently inspected the pipeline as subconsulant to a Patton Harris Rust & Associates(PHRA)/Jason Consultants joint venture for the City of Baltimore. The inspection consisted of a forensic evaluation of the failure and internal inspection of 3.5 miles of pipe. The results of the inspection were provided to the PHRA/Jason Consultants joint venture who is making engineering recommendations to the City.

PURE TECHNOLOGIES SPONSORS UIM WEBINAR

CONDITION ASSESSMENT OF FORCE MAINS

November 18, 2009 2:00 pm Eastern Standard Time

Panelists: Michael S. Higgins, P.E., Vice President Pure US Inc., and Robert Morrison, P.E., Jason Consultants Group

Duration: 1 hour Cost: Free

Wastewater utilities are under increased pressure to inspect and proactively maintain their buried assets. Condition assessment of gravity sewer pipelines has generally become a standard operating procedure for many wastewater utilities while assessment of force mains has remained a challenge. Force mains are often configured such that inspection using conventional methods is not practical or not meaningful as access points are too far apart, lack of redundancy prevents taking the pipe out of service, and the potential problems with pressure pipe may not be identified with conventional methods.

This webinar will review the threats to force mains and discuss how a condition assessment program can be structured to determine if these threats are adversely affecting the condition of a pipe.

CITY OF CALGARY, ALBERTA - FISH CREEK CASE STUDY

Pure Technologies deployed SmartBall within the City of Calgary's Fish Creek Pipeline on June 3, 2009 in order to conduct a SmartBall leak detection survey on the 36-inch, 1.93 mile prestressed concrete cylinder pipeline. Average pressure in the pipeline was 130 PSI. One leak was identified fixed during the project. Upon extraction, the data was evaluated for the presence and location of leaks along the pipeline.

The project was recently highlighted in UIM feature article written by Travis Wagner, P.E. Click here to review the article.
