Most nuclear power plants pump water from rivers or bays for cooling. But some populations lack the resource of water it takes to do this. In Palo Verde Nuclear Generating station water treated in a wastewater sewage plant is piped for 36 miles to a treatment plant then to resevoirs. From that point it goes to the plants tertiary cooling loop. Environmental concerns with this prject is the pipeline required to transfer the water, the property for storage, materials and any permitting considerations.
The chairman of the Atomic Energy Commission compared their system to others by saying -
"It is actually really similar. The water quality of the wastewater treatment is similar to ours--a little more concentrated, because the per capita water use is less. Some of the species that I looked at were a little more concentrated and total dissolved solids is a little higher, but all in all, they are pretty comparable in wastewater terms. They're going to be basically doing the same thing as us."
