Abstract

Sustainable Urban Drainage Sytems (SUDS) are low-cost adaptation alternatives to assist traditional drainage systems, aiming at mitigating the risks of hydrological extremes. In this project, a new nomenclature is used for SUDS, facing the extremes due to change in future scenarios and their adaptations. For example, when they are adapted for changes in land use and occupation, e.g. urbanization, they are called First Generation SUDS (SUDS-1G). When incorporating adaptations of land use and climate change, they are called 2nd generation (SUDS-2G). Also, when the adaptation incorporates the recycling of resources for water-energy-food security, they are called 3rd generation (SUDS-3G). However, scientific gaps still remain because: few studies evaluate the combined qualitative and quantitative efficiency of SUDS-1G and SUDS-2G; for SUDS-3G, there is limited knowledge about incorporating climate change scenarios and resource recycling to reduce water-energy-food security risks; these gaps are still larger in areas of subtropical climate and when applied in a decentralized way. Therefore, this doctoral research enhances a new theoretical-experimental framework on a new SUDS-3G of bioretention, for decentralized use. The methodology addresses three stages: (1) a new design and experimental implementation of a SUDS-3G in a Brazilian city that faces water-food security challenges; (2) new criteria for operation, maintenance and quali-quantitative monitoring of SUDS-3G, in field scale and laboratory scale, (3) proposition and study of new recycling coefficients for water treated by SUDS-3G. The results will be discussed under conditions of: (a) subtropical climate, (b) Brazilian urbanization standards, and (c) social demands for water-energy-food security. This research explores previous advances with SUDS-2G (Macedo, FAPESP 2015/20979-7 and Rosa, FAPESP 13/06611-1), now within the component of "Water Security", co-managed by EESC/USP, together with INCT-Climatic Changes II (FAPESP 2014/50848-9 and CNPq 465501/2014-1), led by CEMADEN/MCTIC and co-led by IAG/USP. The research will be conducted within The WADI lab, working with innovation in water technologies, from an interdisciplinary approach.
