How Inzwa's Vibration and Tilt Monitor Improved DRW Associates' Bottom Line

Updated: Jan 28

For Joel Kurtz, Inzwa's vibration and tilt monitoring system was significantly easier and faster to install, activate and use than traditional geophone-based systems, improving the project's ROI.


Joel Kurtz of DRW Associates installed the Inzwa Veva III to monitor vibration and tilt at the Southerly Wastewater Treatment Plant expansion project in Columbus, OH. “We had plenty of seismographs on hand for monitoring vibration,” Kurtz said. “To monitor tilt, however, we needed to purchase additional equipment. I thought Inzwa’s ability to measure both vibration AND tilt natively without any extra accessories made it ideal for this job.”

Inzwa's solution proved to be significantly easier and faster to install, activate and use than DRW's existing inventory of geophone-based devices. It also improved their bottom line in five key ways:

  • They're saving on installation and activation. With Inzwa’s complete Cloud platform, battery and cellular integrations, it's taking Kurtz minutes to do what had previously taken hours. “Our existing 'graphs, I can get about four in the bed of my truck,” he explained. “And because each box weighs at least 60 pounds or so, to get them to the site I need to use a hand truck to carry and maneuver them,” he continued. Four Inzwa units? I could carry them in a backpack.

  • They're saving on maintenance. His existing geophone-based units require periodic servicing to change batteries. Conversely, Inzwa's robust, fully integrated lithium battery will power the device for up to a year without needing service. According to Kurtz,"Every time I don’t have to make a service trip, I know I’m saving money."

  • They're saving on managing the devices. The simplicity of the Inzwa system saves on manpower, too. “With our current system, we’ve had to have a whole other person dedicated to getting the programming done and monitoring them to ensure the system is working,” Kurtz explained. “With the Inzwa system, though, I can have the programming done before I leave the house just by logging into the Cloud, and I can easily manage the devices myself from my tablet… it basically can remove a full-time role, and that’s a huge difference.”

  • They're saving on the devices themselves. Since the Inzwa Veva III comes fully integrated and ready to go out of the box, there is no need for adding on the accessories that traditional systems require. “With our existing ‘graphs I have to still buy the same anchor and bolt [as with Inzwa], plus the solar panel, plus the modem, plus the battery, the antenna and the enclosure… there’s $1,000 right there,” Kurtz estimates.

  • They're able to get twice the use from Inzwa's dual monitoring capability. Finally, Kurtz is getting a two-for-one benefit from the Inzwa Veva III that his existing devices can’t deliver. “With Inzwa, I buy one unit, I am able to use it for tilt, or vibration, or both - all from one device,” he explained. And it is available for more than just one type of monitoring job in the future. The more the unit’s in the field and on the shelf less, the more profitable it is and the better our ROI.”
