In the 16th century, Copernicus created the world's first shut-off city water supply system with a rise in water to a great height. For this, on the Baude River, flowing near Frombark (Poland), he built a dam, a dam, a sluice and a diversion drip to the city.
A canal about four kilometers long passed under a tower with a mechanical device for lifting water and turned the wheels of the mills built on it. The water rose from the channel as follows: between two prismatic shafts, fixed at the top and bottom of the tower, an endless chain with buckets was stretched, the lower shaft was set in motion by a water wheel, rotating, he moved the chain. The buckets, having scooped up water, were raised to the top of the tower to a height of 25 meters and there they were emptied into a receiving funnel connected to a large pressure tank installed on a hill. From the reservoir, water was distributed through a system of lead pipes to households. This water supply system existed for over two hundred years.
In addition to Frombark, several other cities are known in which a water supply system was arranged, if not by Copernicus himself, then with his participation or according to his system.
