Tired of Emergency Filter Underdrain Repairs?
The Answer is ORTHOS

May 2, 2017 --  Yet another water plant superintendent called me this week singing a familiar tune:

"My block underdrain has blown up and the manufacturer is blaming me
for its failure!"

The second line of this sad song is:

"The manufacturer also claims the contractor didn't install it correctly!"

If one sells a product that isn't resilient to varying conditions and can't tolerate some installation error, is the product truly of high quality? Or is this a case of planned obsolescence? 

And don't forget the third important lyric:

"They have a new product that'll solve all our problems, if we buy today."


X In an industry that demands reliability and resiliency, why are block underdrains being installed over-and-over again? 

X Can one truly believe that the unproven, overly-narrow slotted cap will perform any better over the long-term? 

Wouldn't a monolithic underdrain that features reinforced concrete, is locked into the sidewalls and filter floor, and lasts for many, many decades, be better? 


ORTHOS can utilize the block channel (trough) for installation of an air header and create a short plenum (±12") to minimize hydraulic profile.  With a change of media design, maximum backwash rate, or trough elevation, ORTHOS can engineer a solution that provides excellent distribution, long filter runs, and effective media cleaning.

Remember, ORTHOS has never had an underdrain failure. Don't give into the block guys' demand!
