The drinking fountains on the downtown plaza require cleaning and flushing on a regular basis. They dispense a spring water called "Lithia Water" which is purported to have healing properties. The high level of lithium and other minerals are said to provide that curative effect - but they also cause the fountain's pipes to get blocked up - hence the need for the plunger. The workman was quick to point out that the tool is solely for the drinking fountains and not used for any other purpose.
