Resilient Critical Infrastructure

Once the shift from the notion of sustainable to resilient infrastructure is realized and understood,
it is easier for the concrete pipe industry to advance the case for building sewers and drains with
concrete pipe and boxes. The sustainability of constructing infrastructure with flexible pipe products
can be debated under the three pillars of Social, Economic and Environmental factors (SEE).
It is more difficult, however, to debate the merits of constructing buried infrastructure with materials
other than concrete, if the material is not resilient; and we know by scientific and an abundance of
anecdotal evidence that flexible pipe products and materials are not resilient and arguably not sustainable.

Concrete pipe has a proven track record of withstanding natural and man-made events. There is no
question that it performs as designed for 100 years and more, as both a sustainable and resilient
engineered product.

Canada has its claim of “old concrete pipe”. In 1982, a 30-inch diameter concrete pipe sewer installed
in 1923 was uncovered in Oshawa, Ontario. It contained an expanded metal grid for reinforcement and
D-load tested to Class III pipe. After testing, the sample pipe was repaired and the pipeline restored to
use as a sewer under Oshawa Boulevard (formerly St. Julien Street). In 2011, it was still functioning.
