La PTAR de Piedras Negras s\u2019ubica a l\u2019estat de Coahuila (M\u00e8xic).<\/strong><\/h1>\n

Les obres es van iniciar l\u2019any 2000 a trav\u00e9s del Marco de Cooperaci\u00f3n Transfronterizo entre EEUU i M\u00e8xic, degut a que les aig\u00fces residuals de la ciutat de Piedras Negras s\u2019abocaven al riu Bravo que en aquesta zona conforma la frontera natural entre els dos pa\u00efsos i posteriorment el riu tornava a entrar en terreny dels Estats Units, portant les aig\u00fces contaminades al seu pas per Piedras Negras.<\/h3>\n
