If there is no drinking water – there is no settlement. If there is settlement, there is waste water. Waste water is a constant companion of settlements. In our country, cities and most of larger settlements have already built sewage systems, but many of them have no water purification plant. Waste water is the cause of serious environment pollution, especially the pollution of surface water as well as underground water. The situation is bad with tendency of worsening.

Technical waste water purifiers must be built in all cities and larger settlements. There is no funds at the moment for such a challenging work. Technical water purifiers are needed in cities as well as in small settlements. There are going to be build one day, maybe 2 or 3 decades from now. But, what until then?

Doctrine APU is conceived as the solution for small settlements. It reduces the time of problem solving and avoids planty of problems with the presently common way of problem solving. It frees the communities of small settlements from the need to build technical water purifiers. It gives opportunity to make profit with waste water as a reasurce, without endangering environment. There are 290 small settlements with population up to 3000 in Vojvodina. That is 61.2% of total 474 cities and settlements. In those settlements lives 414.443 inhabitants, what is 21.6% of all inhabitants in Vojvodina. There are 3 to 4 times more of these settlements in Serbia, south from Sava and Danube.
