The purest water on Earth Water from the Shotover River

Take the purest water on Earth, and keep it that way!

At Onsen Hot Pools we capture pure water on its endless journey between the sky and the Earth in order to fill and continually refresh our pools.

To maintain the pristine state of the water we bombard the passing water flow with high intensity ultraviolet rays eliminating the need for the more traditional chlorine, which is better for both you and the environment. Then if required, we add a touch of Bromine leaving our tubs with a clarity and purity to match our surroundings.

We constantly replace the pool water with fresh water, 24 hours per day, seven days per week. Heat exchangers are used to transfer the heat from outgoing pool water to fresh incoming spring water, so while our pools are continually refreshed we do so in an environmentally friendly manner.
