Tap water (running water, city water, municipal water, etc.) is potable water supplied to a tap (valve) inside the household or workplace. It is a principal component of "indoor plumbing", which became available in urban areas of the developed world during the last quarter of the 19th century, and common during the mid-20th century. The application of technologies involved in providing clean (potable) water to homes, businesses and public buildings is a major subfield of sanitary engineering. Calling potable water "tap water" distinguishes it from the other main types of potable water, such as water from rainwater-collecting cisterns, from village pumps (town pumps), or from streams, rivers, or lakes (whose potability varies).

Famous quotes containing the words tap and/or water:
“Anna who was mad,
I have a knife in my armpit.
When I stand on tiptoe I tap out messages.”
—Anne Sexton (1928–1974)
“Thales claimed that everything was water. He also put wine into water to sterilize it. Did he really believe he was putting water into water to sterilize it? Parmenides, like most Greeks, knew that wine was not water. But while lifting a glass of wine to his lips, he denied that motion was possible. Did he really believe that the glass was not moving when he lifted it?”
—Avrum Stroll (b. 1921)
