New Equipment Helps Team Understand Their Sewer Infrastructure

New Equipment Helps Team Understand Their Sewer Infrastructure

Being properly equipped makes sewer inspection more effective. Jim Legg, the wastewater operations supervisor for the Uxbridge (Massachusetts) Department of Public Works, knows this better than most.

“When we got our ROVVER X in 2011, it was our first crawler system,” he says. “Before that we were using an old push camera that could only go 70 or 80 feet down a line. There was a lot that we just couldn’t do.”

When Uxbridge decided to purchase its first crawler, Legg looked to longtime dealer Brian Kennedy of JF McDermott. “We bought from him before and trusted what he had to say,” Legg says. The crew purchased an Envirosight ROVVER X system installed into an Outpost transport enclosure. This gave them the portability to use the crawler how and where they needed, whether down narrow city streets or on easements. Since then, the crew has purchased a Jetscan video nozzle, a Verisight push camera and a Quickview airHD zoom camera.

Versatile equipment proves its worth when a wastewater team has to do double duty. “With the new equipment, we were the best tooled crew in the Public Works division, and in a small town everything has to serve four or five purposes,” Legg says. The wastewater crew is often called in to investigate stormwater and drainage lines. “Some lines are 100 to 200 years old, and you never knew what to expect. The pipe material could change eight times in a run, or you could pop up in someone’s basement. Some were lines that just had dirt thrown over them and now run under someone’s lawn.”

When sewer lines required jetting, the crew had previously been hesitant to run a nozzle blind, not willing to risk catching it on an obstruction or damaging it. With their newly purchased Jetscan video nozzle, they get a better idea of what they’re up against. “We run the Jetscan up the line and when we feel it hit something we can bring it back and see what it is,” Legg says. “Then we pick the best nozzle for the challenge.”

As with any wastewater division, Legg and his crew occasionally encounter frustrated customers complaining of blockages. Using the Verisight with a locator wand, the crew can troubleshoot quickly. “We can pinpoint the location of a blockage and even how deep it is,” he says. “Then when it’s the customer’s responsibility, they can give their contractor the exact coordinates and avoid having their entire lawn dug up. It's put a dead stop to the arguing.”

Many sewer utilities struggle with EPA regulations relating to the Clean Water Act. “We had a lot of work we needed to do to meet EPA requirements and now we’re able to do it,” Legg says. “Our wastewater treatment plant was always great. We even won an award from the EPA. The collection system is where we struggled.” With the ROVVER X crawler and other Envirosight equipment, the crew is able to inspect, clean and repair their collections and stormwater systems effectively. They have moved from being reactive to being proactive.

One of the biggest problems facing Uxbridge before purchasing their new equipment was the inability to effectively understand their sewer infrastructure. This left them unsure of the assets they had and the condition of those assets, frustrating the wastewater crew, contractors and customers. “We never knew what we had underground,” Legg says. “With the new equipment, what was inaccessible has become accessible.”
