Evaluation of the operation and the determination of the loss of water and energy of the 3rd sector of water supplying of Belém metropolitan region. This search was developed in the period of January to December of 2006, in three phases. In the first phase was theoretically determined the operational standard, to make possible the comparison between the results obtained in the second phase, in which one was developed monitoring activities in the water´s reservation and elevation unities. In the third phase was estimated the loss of water and electric energy in the 3rd sector. The results made possible observe that the lack of tools to monitor and control of the standard operational, and the insufficient capacity of the elevated reservoir, results in operations without planned routine, what produces loss of water and electric energy. The volume of lost water was estimated in 423.847 m³/month, what represent 42,58 % of the total volume distributed (989.580 m³/month). The value that the COSANPA does not gain per month with this loss are R$ 508.616,00. The loss of energy referring to the volume of lost water in the 3° sector was estimated in 105.962 kWh/month, what represent a medium cost of R$ 21.192,4 per month or R$ 254.308,8 per year.
