Resumen

El marco regulatorio del saneamiento en Brasil fue instituido en 2007, y las agencias reguladoras tienen la responsabilidad de verificar el cumplimiento de los planes de saneamiento por parte de los proveedores de servicios. Los Servicios de Abastecimiento de Agua y Saneamiento (SAA&S) para aglomerados subnormales tienen características peculiares que exigen de las agencias reguladoras instrumentos apropiados para monitoreo. El propósito de este artículo fue construir un sistema de indicadores para este propósito. Para la selección de los indicadores se utilizó una combinación de enfoques tradicionales y participativos. Se propusieron once indicadores en el enfoque participativo y doce en el enfoque tradicional. Estos indicadores fueron evaluados por expertos y aplicados en el municipio de Cubatão. Como resultado, se presenta un sistema con veintitrés indicadores para monitorear los objetivos de los SAA&S para aglomerados subnormales. El modelo es innovador y puede ser utilizado por la regulación de Incentivo o Sunshine.
