The steady increase in the cost of electricity has caused these tend to become the most significant costs of the operation and maintenance of the plant wastewater treatment plant (WWTP).

The purpose of this research is to determine the relationship of energy consumption of a WWTP with the main characteristic parameters of its operation, for this reason it statistically analyzed 538 plants in Eastern Spain (Region of Murcia and Valencia).

The results gave an average consumption weighted by flow of 0.42 kWh / m3 and 2.78 kWh / equivalent population, and that the ratio of energy consumption vary through a negative exponential relationship, showing that the ratio of power consumption of the WWTP increases with decreasing the size of the population served.

The final conclusion is that, whenever possible, is warranted the tendency to design wastewater treatment plants as large as possible, grouping the discharge flow rate of several scattered populations.
