announcing the pwqa
66th annual trade show & convention

The PWQA 66th Annual Trade Show & Convention was held from Wednesday, October 11 to Thursday, October 12, 2023, at the Hilton Irvine/Orange County Airport, Irvine, CA. Plan to attend our major annual event for all industry members where advancements are shared and ideas flow…

Last year with eleven educational seminars presented by seasoned industry experts and more than 30 exhibitors, representing major manufacturers and distributors, our in-person show was a great opportunity for industry members to learn, to reconnect, and to catch up. Plan now and mark your calendar for you and your staff to attend this very important trade show and convention for our water industry in the west coast!
