What that means for your Geneva home
Because Geneva already treats its water before it reaches homes, many homes here do not need a whole-home softener.
We don't sell the drinking-water system on its own yet. It is a 5-stage reverse osmosis system under your kitchen sink, with its own faucet, and it comes with the City Water Package ($3,299 installed, whole-home softener included) or adds $699 to the Well & Hard Water Package. If a drinking-water system is all you want, we're not the right fit today.
