The following issues have been accentuated: the specific features of developing programs for improving the environmental efficiency for water and wastewater utilities operating public wastewater disposal systems in settlements and urban districts that discharge effluents into the Baltic Sea catchment basin; the required dates for developing and approving the programs. Attention is drawn to the need for strict compliance with the requirements to the program components. Particularly noted are the nuances of comparing the actual quality of discharged effluents in relation to the technologically regulated substances with selected process parameters of the best available technology. Examples of the analytical evaluation of the choice of indicator values and technological solutions for the stages of the program activities are given. The focus is drawn toward the need to analyze all the best available technologies regulated by the adopted information and technical reference books. The aspects of highlighting the results of the inventory of pollution discharges in the programs are indicated.
