Obetz is supplied by Columbus Water & Power as a contract community. Columbus treats Scioto River and Big Walnut Creek surface water, and Scioto Valley groundwater at the Parsons Avenue plant. The 2025 report lists finished-water hardness of 5.7–7.3 grains per gallon by plant (98–125 mg/L) and a system summary of 115 mg/L. The city does not publish which plant feeds a single Obetz address, so that range is the number we use, and we still test at the house. Columbus Water & Power says a home filter is not required to make the water safe to drink. On this supply, a softener or filter is a choice about taste, odor, scale, and how appliances wear, not a safety fix.
