摘要：O objetivo do presente trabalho é medir os custos da Estação de Tratamento de Água (ETA 06) devido aos processos de assoreamento do Ribeirão Taquaruçu Grande no município de Palmas –TO. Para valorar esses danos, utilizou-se a metodologia de valoração ambiental denominada custo-reposição. Como resultado, pode-se observar que os principais fatores condicionantes do processo de assoreamento são: a implantação, o constante tráfego de veículos nas rodovias TO – 030 e TO – 020, a ocupação antrópica na bacia, bem como o desrespeito às áreas de proteção ambiental - APA’s - dispostas em suas margens. Identificou-se um valor anual correspondente a R$ 73.472,20, sendo este o valor necessário para o bom funcionamento da ETA; no entanto, os gastos para reparar a degradação do Ribeirão ainda podem ir além.

The purpose of this study is to measure the costs of the Water Treatment Plant (WTP 06) due to the Great Stream of Taquaruçu sedimentation in the city of Palmas, Tocantins. In order to evaluate the damage it was used the methodology of environmental valuation known as replacement cost. As a result it can be observed that the main factors responsible for sedimentation process are: the implantation and constant vehicle traffic on highways TO-030 and TO-020, anthropic occupation in the watershed, as well as the disrespect for the environmental protection areas –which are placed in its margins. It was identified an annual value corresponding to R$ 73,472.20, which is the amount necessary for the proper functioning of the WTP, however the cost to repair the degradation of stream can still go further. Key words: aggradation, valuation, supply, replacement costs
