Alternative engineering solutions for water pollution minimization from urban drainage systems - The case of Rio de Janeiro, Brazil

& Jord\303\243o E.P.
Tropical climate countries use separate, instead of combined sewer systems. However, legal and illegal sewage connections to the urban drainage system result into local water resources pollution. This paper discusses the problem causes, and shows local, alternative and original solutions that have been adopted in recent years for its minimization in Rio de Janeiro State. It presents practical examples of engineering solutions, emphasizes their applicability, advantages and disadvantages, as a contribution for the theme discussion...
