For a cleaner

Serbia is ranked 47th out of 180 countries by the amount of water resources it has. Serbia holds more than 20% of the world's fresh water reserves. Serbia is among a few European countries that has the richest sources of mineral water, despite the statistics, every third water supply in Serbia is under risk of delivering water that is below the level of quality microbiologically and chemically safe.

A particular problem is underground water pollution, and water pollution from unregulated landfills.

Sooner or later, all the waste, reaches the underground water, and pollutes it. Water can be protected from the waste by construction of landfills with controlled drainage. The biggest polluters of surface water and groundwater are petroleum and petroleum products, chemicals, waste water and industrial water, urban waste water from sewage and landfills of industrial and municipal waste.
