An impending pipe repair crisis

Across most developed regions of the world, massive networks of underground water and waste infrastructure installed between 1930 and 1980 are now reaching 'end of life'. Reports of leaks, breaks and blockages in these pipe systems have been rising sharply in recent years, and with so much of the infrastructure buried beneath now heavily-populated cities and roads, many feared there was an impending crisis in terms of destruction, disruption and cost if our only way of repairing these pipes was to tear things down, excavate the pipes and lay new ones.

But as has occurred so often in the past human creativity and ingenuity have conceived and brought forth concepts and technologies right when they were needed, in response  to an imminent threat.

Thanks to breakthroughs in the fields of science and engineering over the past decades, innovative and environmentally-friendly technologies have now emerged, which make it possible for broken pipes to be repaired from the inside, without the need to dig at all. Known as trenchless repairs, old pipes (or their remnants) are usually left in place while a new pipe (often made with tough, durable composite resin materials) is simply formed or situated inside or around them.

These devlopments are significantly mitigating the threat our aging pipe systems once posed and have reconfigured contemporary approaches to urban infrastructure renewal programs. 

As with all new technologies, however, we need to keep pushing the bar in terms of what can be achieved, which means asking the right questions and coming up with the right answers. 

 

Question: Do relined pipes flow better?

One such question is whether certain trenchless repairs of damaged or broken pipes impact the pipe's flow rate capacity. This article will look at one of the most popular forms of trenchless repair, Cured-In-Place piping (CIPP), and assess the impact it has on a pipes functionality.
