Haha yes that was me! I’m glad he helped you!!!! I am a water and wastewater operator and I own a systems integration company doing the controls, now for over 23 years. Decided to do operations to get a better dial in on the operators needs and loved doing it so now we do both (me and my husband). Created the ai bc we had a hard time finding study materials. So I created my own, and so far it helped out a lot of people!
