While the City *does* have an issue keeping fountains working, the issue here isn't that it isn't working or isn't designed well. The City is always slow to turn on its fountains in the spring because, IIRC, they have one guy (or one team of guys), who go around and test and then turn on each fountain. Apparently, it takes them awhile to do this, and to get through the list. This was reported either in a thread here, or in the Fixer column in the Toronto Star ... I can't remember. It's a cockamamie system, with the least amount of flexibility possible, but it is what it is.
Anyway, that's my recollection. If I have it wrong, someone here will know the more accurate facts.
The reflecting pool at NPS has just been filled, and the spray fountains by City Hall are now on. The city must be going through the list as we write, one at a time.
