More or less all offices these days have water cooler installed in the office premises and buildings. In many of these offices, coolers are installed in almost each floor. These coolers are mostly attached to the main source of water in the building. Mains fed water cooler makes drinking water available throughout the day ensuring people need not have to crave for it. Water coolers are of different types. They can be mounted on the wall, fitted under sinks or used as counter top machines. Some of these water coolers save clean water up to a certain quantity while others give running clean water for drinking and cooking purposes.
