APLICA O DO GEOPROCESSAMENTO NA AVALIA O E ESPACIALIZA O DAS PERDAS FíSICAS DE áGUA DO SISTEMA DE ABASTECIMENTO PúBLICO DE RONDONóPOLIS - MT / Application of the Geographic Information Systmems in the evalution and spatial distribuition of the physical losses of the System of Water Public Supplying of Rondonópolis - MT

The study had as objective to investigate the levels of physical losses of water of the supplyingsystem of Rondonópolis-MT operated by the concessionaire Service of Ambient Sanitation ofRondonópolis – SANEAR. The data used for this study are of production and consumption ofwater in Rondonópolis, in the period of years of 1998 the 2003, supplied by SANEAR for thelevel of the zones of water production of the city. Through statistical analyses and resources ofGeographic Information Systems, this data has been used for to evaluate and to distribute inthe Rondonópolis space the rate of physical losses of water of this system and to identifyseasonal variations of the levels of water consumption. As main results, they had been verified:a) verification of the seasonal variations in the levels of water consumption of the city being it 5% below of the annual average in the period between the April and January months and 5%above of this average in the period of August the December; b) verification of high rate ofphysical losses of water in the supplying system of Rondonópolis which exceed 50% in themajority of the 16 zones of water production of the city and in two of them had arrived about90%. In average the losses of water had been of 55% in Rondonópolis for the two analyzedyears, exceeding the average rate of Brazil (40%) and of the Center-West Region (44%) oflosses of invoicing (PMSS, 2004:19).
