GÖTEBORGS VATTENPRODUKTION 1987 / Gothenburg’s Water Supply
The City of Gothenburg got its first water supply system two hundred years ago, in 1787, when water from the spring at Kallebäck was conveyed to the town centre. Later on installations at the Delsjö Lakes and at Alelyckan were built, in 1870 and 1894 respectively. At the present time the City’s supply of drinking water is based on the river Göta älv and processed by the water treatment plants at Alelyckan and Lackarebäck.
In 1968, the Lackarebäck Project was completed – water is taken from the Göta älv through a series of tunnels, and pumped to the Delsjö Lakes, and from there to the plant at Lackarebäck. The lakes also function as a reservoir for the plant at Alelyckan. Both the treatment plants work on the chemical precipitation principle, using activated carbon filters. The plant at Alelyckan has equipment for reactivating carbon.
