The paper addresses the issue of sustainable development in the field of water resources. A description of two Goals of the Moldova 2030 Strategy is provided: SDG6 and SDG14, both of which prioritize the reduction of water pollution. It shows how these goals complement one another. In order to successfully achieve these Goals, certain international practices for the elaboration and development of software tools must be implemented. The practices mentioned above allow the creation of models for predicting the water quality of aquatic ecosystems. The study of the most frequently used methods and software tools for controlling water pollution currently used is presented. Hence, it is proposed to use software tools to improve the situation of water pollution in the context of sustainable development.
