water was used by the water supply system, instead of water springs. Original capacity was per day, for 80.000 citizens. By 1914, the production grew to daily. As Belgrade grew in the decades to come, the first water treatment facility ("water factory" Makiš 1) became operational in April 1987. It treats water from the Sava river. Another treatment facility, Makiš 2, was built from 2004 to September 2014, which should cover Belgrade's need for water until 2035. During the Interbellum, the waterworks company built the residential complex for its workers in Makiš, which originally consisted of two buildings within the industrial facility. Makiš Stadium is located in the northern section of Makiš. Makiš Field Eastern section, across the Sava motorway is called Makiš Field (). In the south and south-western section the Makiš marshalling yard and the neighborhood of Železnik are located. After several plans for the Belgrade Metro since the 1960s, a new plan was announced on 3 July 2017, which envisions first two lines as the long Makiš-Mirijevo (via Sava Amphitheatre and Karaburma) and the long Zemun-Ustanička. The construction should start in the end of 2019 or the beginning of 2020 and should be finished in 3 to 4 years. The project differs from all the previous ones as it sets the crossing of the major lines under the Belgrade Waterfront on the Sava bank, a highly controversial pet project of President of Serbia Aleksandar Vučić and mayor Mali, instead under the central city squares of Terazije or Republic Square as planned in the previous decades. Mayor of Belgrade Siniša Mali also announced that the first line is actually going to be Makiš Field-Mirijevo (that is, Višnjičko Polje) instead of Zemun-Ustanička which was planned as the first for decades. Architects and engineers reacted negatively, especially since both terminuses are at the moment nothing more than still un-urbanized heaths, though mayor Mali said that this line will connect the future projects which will "with the development of metro, bring billions of euros in investments and millions of square meters of the new business areas". Dr Ratomir Vračarević, traffic engineer and professor at the University of Belgrade's Faculty of Technical Sciences said how the surveys showed that this direction has a very low number of potential commuters, well below the profitability level. Architect Branislav Jovin, who authored the 1970s subway project, said that he believes Makiš was chosen because of
