What's wrong with shit water? It's what the largest nuclear plant in the US uses for cooling. Sewer water is pumped in from Phoenix and used to cool the plant.
>Palo Verde generates the most electricity of any power plant in the United States per year, and is the largest power plant by net generation as of 2021. The Palo Verde Generating Station, lying in the Northeastern Sonoran Desert, is the only large nuclear power plant in the world that is not near a large body of water. The power plant cools and condenses the steam that it produces by using treated sewage water from several nearby cities and towns.
