Macro level
Major task of a municipal water supply control at macro level is a search for an optimal load balance among water intakes.
For this purpose the system determinate relationship between specific costs for extraction and delivery of water to a city and the volumes of extraction for each water intake. After that, based on the admissible range of delivery change and forecasted consumption for every water intake the economically optimal load for each water source is calculated.
Calculation of specific water cost includes power consumption of all pumps engaged between the specific water source and its consumer as well as the cost of water treatment. Boosting pump stations associated with the water intake at each particular moment of time are recognized by degree of correlation of their inlet pressure and outlet pressure of the water intake.
