1 espace piscine (5 m x 15 m) de forme irrégulière avec 1 bassin de nage, 1 bassin en terrasse avec bains à remous (non chauffés), geyser, chutes d'eau.

One item in a list describing pool features and characteristics.

I came across "geyser" in a pool context through searching on the Internet, but that's not a word I usually associate with pools. Is this perhaps a British term? The target audience for this project is actually British, so that would be fine if it is. Thanks in advance.
