Which is a better bargain: plumbed in water coolers or bottled water coolers?
Bottled water coolers make less sense if you have limited office space because storage of new and used bottles takes up a lot of room. They also require lifting 10-20-litre bottles to place into the receptacle. Plumbed-in water fountains require no transportation of course, and they are more economical. But they may only be located where the water pipes are located. The major advantage of plumbed-in water is that it is a constant source that taps infrastructure already in place, eliminating the need for transporting, storing and lifting heavy water bottles.
