With the additional conditions influencing the climate change and the population growth, it has added more pressure to the problems of sewage management systems and innovative cleaning technologies. Some different approaches for more effective management of water resources are analysed in this paper. The solutions can be tested whether they have led to the sustainable development of the countries such as Turkey, by taking more attention for best practices of EU countries (for example as Netherlands). By evaluating requirements of sustainable development we are trying to extract different criteria which help to evaluate the situation in water management sector. A case study of water treatment facilities in one enterprise (the Fertiliser Complex in Turkey) is analysed. Results show how some methods such as the highest consumption of wastewater evaluation and TOPSIS can help in situation evaluation process. The most wastewater consuming production zones are determined in the Fertiliser Complex and some pollution factors are determined according to the TOPSIS method.
