Google is your best friend here. Type in: “water supplier for [your address].” You might get an instant result from a government site. Or try the Environmental Protection Agency (EPA)’s local tools. They have a “Find Your Local Drinking Water Source” feature.
Another pro tip: search for “municipal water [your city].” That often spits out the official name. And if you’re rural? You might be on a well. That means you’re the supplier. Congrats, you’re the CEO of your own water!
