Often enough to keep the water cold
Generally I will change my bong water as often as I remember to, which is about every 1 or 2 uses if I cant empty it after I use it. When I empty it I splash some rubbing alcohol in it and swirl it around to sterilize it at bit. It keeps the smoke and stuff fresh and easy to inhale and is generally good practice.
The residual THC and combustion products in bong water should be a fairly effective antimicrobial. That said it's still not anything you need to be consuming.
Using fresh water is best, change it daily or every few bowls.
