A metodologia de dimensionamento de sistemas coletores de esgotos sanitários utiliza a centenária fórmula de Manning para os cálculos hidráulicos em condutos livres, apesar de não ser uma unanimidade nem homogênea. Ademais, os critérios de rugosidade e de autolimpeza em condutos são baseados em valores fixos que não consideram a sinergia dos parâmetros físicos e hidráulicos em situações reais operacionais: biofilme, sedimentos e obstáculos. Portanto, esse livro aborda pormenorizadamente 168 fórmulas de dimensionamento hidráulico e 133 fórmulas de transporte de sedimentos para critérios de autolimpeza em condutos, além de avaliar as normas e os critérios praticados mundialmente para, na sequência, modelar tanto as fórmulas existentes quanto as novas fórmulas aqui propostas, contemplando 5.105 dados bem representativos da operação de coletores de esgotos de todos os tipos de sistemas: separador, unitário e tempo seco, com diversos diâmetros, materiais e condições de uso. Destes dados, 312 foram obtidos pelo autor em experimentos na UFRJ e em coletores no Rio de Janeiro. Após análise e validação dos modelos propostos, novas fórmulas compõem uma nova metodologia de dimensionamento hidráulico de coletores sanitários, mais representativa das situações reais operacionais, incluindo novos modelos para critérios de autolimpeza e novos critérios para valores de rugosidade em projeto. Com isso, espera-se uma maior sustentabilidade nos sistemas sanitários ao redor do mundo. 10
