This page covers eight events worth knowing about, ranging from regional trade association summits to large-scale water infrastructure gatherings. AWWA ACE in Washington, DC runs June 21 through 24 and draws water utility professionals at a national level. The CIPH Annual Business Conference in St. Andrews by-the-Sea is a tighter, relationship-focused event for Canadian industry leaders earlier in the month. If you're planning booth presence, partnership meetings, or just keeping tabs on where buyers and specifiers are gathering, this list gives you the actual dates, locations, and context to prioritize. KBIS 2026 drives a lot of search traffic in this space, but June has its own calendar worth tracking separately for anyone focused on plumbing supply, mechanical contracting, or water systems work.
