Perpetual Fountain

This simple fountain produces an endless flow of clean, fresh water. Town and city water systems commonly use them. It will produce 7,200,000 gallons per day, enough for a thriving fantasy city.   A Perpetual Fountain provides a generous, and utterly reliable water supply regardless of location. At least as importantly, it provides clean drinking water, uncontaminated by microorganisms or evil spirits (depending on the world background).   The classic Decanter of Endless Water can produce 432,000 gallons of water a day, enough for roughly 5000 modern American households, 10,000 worldwide average ones, or 20,000 medieval ones. The Perpetual Fountain may simply use an immobile variant (x.5 cost) or a higher level spell. The most common design uses Create Liquid (Water) at level 3.
