Thanks for taking the time to read our newsletter—although this month seems to offer more visual highlights, including two great videos and an article that showcases detailed and interactive before and after images. 

As always, if you have a question or need help, whether it's for a brand new project or even researching past studies we were part of (it does happen), give us a call or submit your inquiry online. 

Now, let's get to this month's round-up. Read on, stay safe, and make sure to follow us on our social channels.


One of the buildings on our Holden campus is nearly filled with scientifically useful and visually beautiful design tools (aka hydraulic models). Their purpose? To evaluate flow patterns for any negative impacts under an array of operating conditions so that clients can ensure expected performance, reduce maintenance and increase their project's lifespan. 

Take a look for yourself and venture a guess as to how many models are running in this video.
