Last month we discussed why consistent joint testing is a crucial and sometimes overlooked steps. This month, let’s get practical and outline some common ways you can joint test, break down the benefits and drawbacks of each, and summarize the steps involved. To start, there are essentially four ways to joint test.

Joint testing of pipe and structures is still seen by some as an unnecessary or unrealistic extra step, but without it we risk far more than just a leak. Plenty can go wrong during and after the homing or installation process, whether because of an open joint failing to create a seal with the gasket or a bad seal allowing infiltration or exfiltration. Testing takes the uncertainty out of the sealing capability and means a better product, installation and conveyance system for everyone involved.

Water and wastewater management infrastructure has evolved hand-in-hand with human civilization for thousands of years. What is astonishing is how incredibly important this technology still is in present day, and most people aren’t even aware of its presence or function! You would think that, by now, cities would have this thing pretty much covered, but the billions of dollars spent every year on repairing and improving this infrastructure is a sure sign that, as society continues to evolve, how we handle our water and waste will continue advance in lockstep. To illustrate this, we gathered together a quick look at water and wastewater infrastructure over the centuries.

Municipalities have traditionally used open cut techniques to install pipes underground. Because it requires digging along the length of the pipeline, the method can be tricky to set up in specific environments. What happens when you have traffic congestion near the installation area? What if you’re working in a heavily used space in the public right-of-way, or if you want to avoid extensive damage to street pavement?

Precast concrete box culverts are essentially the Legos of the construction world. You have a set number of pieces, and if they’re gasketed on arrival, there is no extra work except simply putting them together. They slide into place one-by-one and you’re good to go.

Large, high-profile upgrades to sanitary systems often focus on the pipe-to-pipe connections while sometimes neglecting the connections between a pipe and a manhole (maintenance hole). Pipe-to-manhole connections, while absolutely vital in a sanitary sewer system, are quite important in a stormwater system.
