All the time - lots of info here http://houseplants.about.com/od/bromeliad1/p/Aechmea.htm
Rainwater is best.
The compost should be free draining and when you water it the water should run straight through leaving the compost just slightly damp. Never let it stand in water. The 'roots' aren't roots as we think of them, they just anchor the plant.
Don't add any fertiliser to the water. Mix up a quarter strength Baby Bio with some fresh rainwater and spray the foliage occasionally during the growing season only.
Mature plants will take up some feed/water through the roots, but 'in captivity' they've no need to.
