Volschan E.P., Jord\303\243o Alternative engineering solutions for water pollution minimization from urban drainage systems - The case of Rio de Janeiro, Brazil DTU Library, Technical University of Denmark (DTU) 2005 Urban drainage system sewer system sewerage water pollution Federal University of Rio de Janeiro, Water Resources and Environmental Engineering Department en Conference full text 10.4122/1.1000001207 application/pdf 1 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 in the scenario of developing countries.
