Swimming pools have been with us since Greco-Roman times. The ancient Greeks and Romans built and used them for athletic training, nautical games, military exercises, and other such purposes we might call commercial today. The Roman lord Gaius Maecenas is believed to have built the first heated swimming pool in the first century B.C., and the first popular pools are thought to have appeared in Great Britain in the early-to-mid 19th century.
Modern swimming pool construction techniques and materials began to appear in the 1930s, when Paddock Pools introduced a pneumatically applied concrete and sand aggregate mix, known as gunite, for pool construction. This substance enabled pool builders to fashion free-form pool shapes and recycle, in effect, the dirt excavations for a pool’s framework. In the same decade, the company came forth with silicate, a white silica sand plaster, as the first known non-tile pool finish.Swimming took off in popularity following the birth of the modern Olympic games in 1896, which included swimming races. The actual appearance of the first swimming pool in the United States, commercial or otherwise, is difficult to determine, but by 1907, the Racquet Club of Philadelphia included one of the world’s first above-ground pools. Moreover, though they are familiar fixtures on cruise ships today; the first known swimming pool to feature on an ocean liner was on the Adriatic, a White Star Line ship, in 1907.
Commercial swimming pools are built for resorts and housing complexes, municipal recreation centers, schools, military facilities, and competition complexes. Community pools are designed in numerous shapes from standard rectangles to free-style mini-water-park appearances. Competition pools are typically rectangular, and often as not municipalities prefer these to double as community recreation and community athletic program pools. In addition, they require more acute, sophisticated, and fast filtration systems than private residential pools normally require, because far more people use these pools than a typical family uses a private residential pool.
Paddock Pools also developed a mechanical skimming device, when a company technician fashioned a system of recirculating overflow, allowing surface water to be cleaned through the pool’s own filtration system. It took another company team to solve the problem of expensive pipe maintenance by developing a manufactured pipeless perimeter, which now use steel channels to bring the water to the filtering system and removing any need for perimeter piping. Moreover, in the 21st century, Paddock has developed ultraviolet light purification for swimming pool use.
Today, advancements in swimming pool heaters are once again revolutionizing the industry. From solar to geothermal, alternative energy sources are being used to heat pools and save money on utilities.
