Through the "flake" system of dispersion, the water filters itself through the non-organic wall, made of gravel, sand and other silicate minerals, before reaching the reservoirs.

The central facilities (including the water factory) of the Belgrade waterworks are located in Makiš, so as many gravel digging and cement plant on the bank of the Sava river.

[4][14] 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.

[19] Eastern section, across the Sava motorway is called Makiš Field (Serbian: Макишко поље, romanized: Makiško polje).

[20] 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.

[21] 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.

[21] Three weeks later, city indeed announced that Karić's company "BK Group" won the competition for the project of "Tesla Grad" in Makiš Field with Mali personally giving advice what should be built in the complex.

On the very day when this was announced, Karić stated that he already finalized everything at the meeting with Mali and city architect Milutin Folić and that the project is just one step away from realization.

The starting point of the new settlement, from the city direction, will be a residential and commercial complex (apartments, shops, elementary schools, kindergartens, ambulances, cultural and sport venues, hotels) surrounding the 25-storeys high skyscraper.

In order to accommodate such a big project and make it possible, city government actually reduced the buffer zones by half around the water sources.

[25][26] In September 2017 it was announced that the National Stadium will probably not be built within the scopes of Tesla Grad as there are complicated issues concerning the ownership of the land in Makiš.

[28] City also claimed that the urbanization of Makiš was already planned in 1974 and that 2015 study by the Institute "Jaroslav Černi" which was used to reduce the buffer zones, was ordered in 2009.

[29] "Jaroslav Černi" refused to comment publicly claiming they are understaffed due to the pandemic,[6] but later issued a statement that there is no ecological concern.

[6][28][29][30][31] On 30 December 2020, amidst protests and minor physical confrontation with the security guards, city assembly adopted the plan for the urbanization of Makiš.

He claimed they planned to build cheap apartments which pose no threat to the water sources, but after talking with the local residents and various organizations, they backed off as they met with lack of understanding.
