Chlorine or bromine residuals are the common disinfectant in municipal basins. Some venues use ozone or UV as a supplement, not a replacement for a residual. In a shared lane, swimmers keep right (or follow the posted direction), pass in the middle, and leave space at the wall. It is etiquette, not a race rule.
Walls, lines and a known depth remove current, swell and sighting. Open-water chapters cover the skills the pool cannot teach. Artificial basins are older than sport swimming. Roman thermae and later Ottoman hammams were social and hygienic spaces. Competitive swimming in measured pools is a nineteenth-century export from Britain and continental Europe.

The 50-metre standard and the 1908 founding of FINA (now World Aquatics) locked the pool into Olympic sport. Municipal learn-to-swim campaigns after urban drowning spikes made the same basin a public-health tool. The pool is a nineteenth-century public-health machine that sport later colonised. Its history is as much about cholera acts and school timetables as about Olympic gold.
Pool culture splits three ways: the school lesson, the dawn masters lane, and the Olympic broadcast. They share water and almost no vocabulary. Bathhouse traditions — Budapest, Tokyo sento-adjacent pools, British lidos — sit beside US high-school swimming, a sport-media complex of its own.
