Established in 1804, this plant used gravel filters and concentric sand to treat water, and the water is distributed with the use of a horse and cart. in 1827, robert thom invented slow sand filters, which were installed in greenock, scotland, and two years later, james simpson came up with a similar system that became widely used around the world.
