IWEA & IWWSG 2026 Joint Pretreatment Discussions & Dinner

Join us for our annual joint association dinner meeting!  We have something for everyone in pretreatment - including the industrial users.
This year's panel features an engineering consultant and an attorney who work directly with industrial users on responding to NOVs and finding practical, technical compliance solutions -- plus a Control Authority pretreatment coordinator offering clear insight into what regulators expect from industry and advice for Control Authorities.


A rare chance to gain guidance from both sides of the table -- all in one conversation.
Dont't miss it!
