Industry Editorials

Association staff and member companies of the CCPPA publish in several publications, including Concrete Pipe Journal, that cater to the buried infrastructure industry. This page archives articles that address product and materials application and the wide range of issues that affect the concrete pipe and precast products industry.

Project of the Year - New Installation - Rebecca Trunk Wastewater Main

As part of an effort to keep pace with a growing population, Halton Region, located within the Greater Toronto Area (GTA) in southern Ontario, began a program to update its sewer system. One major component of that program, the Rebecca Trunk Wastewater Main, not only represented a major step in meeting future infrastructure demands for the region but also for microtunneling in North America.

The project involved more than 4 km (2.5 miles) of 1,200 and 1,350 mm (48 and 54 in.) microtunnels within Oakville, an urban and affluent town along the shore of Lake Ontario. The project included nine microtunnelingdrives (eight curved) ranging in length from 180 to 626 m (590 to 2,053 ft), with seven of the drives completed in rock.

Initial cost shouldn't be the primary factor in choosing gravity pipe systems

An article by Gerry Mulhern published in the April Issue of Environmental Science & Engineering Magazine

Municipal and consulting engineers can sometimes lose sight of project life and serviceability expectations when it comes to gravity pipe storm drainage systems and sanitary sewers. Too often, decisions are based on the initial cost of the pipe and not enough consideration is given to the cost of proper installation, maintenance or rehabilitation costs, and service life.

Assessments of Gravity Pipe Systems - Initial Pipe Cost Not The Primary Consideration

Engineers are regularly facing budgetary challenges. Designing and building infrastructure to stay within budgets becomes the primary focus, and municipal and consulting engineers can lose sight of project life and serviceability expectations. This is particularly true when it comes to gravity pipe storm drainage systems and sanitary sewers. Too often decisions are based on the initial cost of the pipe and not enough consideration is given to the cost of proper installation, maintenance or rehabilitation costs and service life.

Municipalities should conduct assessments of the various gravity pipe systems that are available. It is important to distinguish between the terms “pipe systems” and “pipe materials”. Pipe systems include the pipe material, couplings or joints, fittings, connections to maintenance holes, and embedment materials. A thorough pipe assessment will
examine the following key issues:
• Technical
• Financial
• Risk

Constructing massive precast concrete structures with CON/SPAN® presents choices to design engineers and assembly options to contractors. Working with thirty tonne CON/SPAN units on the Denison Road Storm Water Retention Tank in Toronto required highly skilled installers and a Goldhofer transporter, called a “crawler”. In addition, a 160 tonne crane was required for offloading and placing the units on the crawler used to assemble a portion of the 144.5m structure located one metre below the finished grade of Denison Road. Without modern technology and the precast concrete CON/SPAN system, the precast units for the tank could not have been assembled within the 10-day period in the summer of 2014.
