The first documented use of sand filtration to purify the water supply dates back to Scotland in 1804. Since then, the technique has been continuously refined by water professionals and those gradual tweaks have allowed it to stand the test of time. The development of continuous backwashing filtration, made in the 1970s, was one such tweak.
