Water treatment in
Hamilton County.

Hamilton County is where Aqua Otter started in 1999 and it is still the densest part of our install map. Water comes out of the ground hard, 19 to 20 GPG depending on the wellfield, and most homeowners notice scale on glass shower doors and spotting on stainless within a few weeks of moving in. Carmel, Fishers, Noblesville, and Westfield each have their own utility but draw from the same alluvial aquifer system, so the hardness story is consistent across the county. Chromium-6 and seasonal TTHM spikes show up on every CCR we pull here.
