Orthos Celebrates 25 Years of Excellence With Champagne Toast at WEFTEC23

October 26, 2023 – Orthos Liquid Systems, Inc. (ORTHOS) celebrated earlier this month at the WEFTEC23 exhibition the 25th anniversary of never having a Centurion™ monolithic filter underdrain failure. The champagne toast by Stuart F. Humphries, Director of Filtration Technologies, thanked water/wastewater treatment clients, engineers, contractors, and manufacturers’ representatives for the over 250 installations that continue to repeatedly deliver the resiliency, reliability, and longevity that utilities demand. 


Humphries stated that in Orthos’ “25 years of never having a monolithic underdrain failure, our competition has a completely different experience. And with us getting out into the marketplace and with folks like yourself helping us get the word out, things are happening. I’m excited—super excited.” Continuing, Humphries told the audience that Orthos is “very thankful for you to getting the word out and convincing people: Don’t go with folded sheet metal, don’t go with plastic block, go with the reinforced concrete monolithic Centurion underdrain from Orthos. So here’s to Orthos—25 years and 25 more years!”

Why does Orthos want the toughest post-installation testing of gravity filters in the W/WW treatment industry? Our competitors offer an overall less-effective underdrain system while falsely promising the same results that Orthos delivers time-after-time.

Orthos has demonstrated repeated success in BAFs and BACs with our monolithic design. Monolithic filter plenums allow backwash water and air to move in two directions, this advantage is extremely important in BAFs/BACs.
