>All the while, fiercer heat waves will require more energy-hungry air conditioning to keep people healthy. (Though ideally, everyone would get a heat pump instead.)
I grew up in an agricultural area and the water was completely untreated. It was literally a canal from the river that was then sprayed onto fields. It wasn't uncommon to have to clean out small fish from the irrigation pump's filter. Sometimes you'd lose water pressure completely and have to drive down to the irrigation ditch and clean a racoon carcass or something out of the intake grate.
