Dakle, "project developer" za projekat gradnje postrojenja za tretman otpadnih voda su grad i JKP Naissus. Oni imaju svoje izvođače (contractors).

Project developer (the city of Nis and the Public Utility Company "Naissus”) will cooperate with relevant local city authorities and departments during project design and throughout the implementation of the project. Regular meetings will be held to discuss any issues.
