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.

Vazamentos na rede de distribuição de água: impactos no faturamento e no consumo de energia elétrica do 3° setor de abastecimento de água da região metropolitana de Belém

Analysis of the estimate of losses billing of electric energy due the leak in the net of water distribution of the 3rd sector, managed by the Companhia de Saneamento do Pará (COSANPA) in the metropolitan region of Belém (RMB). The search was held done in 5 (five) stages. In the stage 1 was identified the month with major occurrence of leak in the period of May 2006 at Abril 2007, for detailing of the occurrences (local, diameter of the net and occurrence time of each leak) in the second phase. After it was estimated the flow (phase 3) and the volume lost (phase 4) in the net of water distribution of the 3rd sector. Finally in the phase 5 was estimated the losses of billing and electric energy. The results obtained show the necessities of deployment of a programme of reduction of losses in the net of water distribution of the 3rd sector. The greater volume of lost water occurred in the month of November 2006, causing loss of turnover of R$ 20.906,32 corresponding to the volume of 14.933,08 m3 and the electric energy on the value of R$477,80 correspond at 2.389,93kWh. With the work was possible see that the leaks in the net of water distribution of the 3rd sector damage the system performance and the revenue of the company.
