The implementation of Sustainable Urban Drainage Systems (SUDS) can counteract these causes since they retain runoff usually in a maximum time of twelve hours and evacuate it to water bodies or to the sewerage system. The objective of this research is to facilitate the sizing of bio-retention zone type SUDS by updating the pre-sizing sheet prepared by the Bogota Water and Sewage Company, the District Secretariat of the Environment and the University of the Andes. The two methodologies included in the sheet have been updated and a new sizing methodology focused on improving water quality has been added.
