Cartilla para la implementación de sistemas de drenaje sostenible (SUDS)

Abstract

Urban growth has increased soil impermeabilization, leading to issues such as flooding, reduced infiltration, and deterioration of water quality. Sustainable Urban Drainage Systems (SUDS) have emerged as alternatives that help restore the hydrological cycle through processes of retention, storage, and infiltration. This handbook provides a practical guide for the implementation of four SUDS typologies selected for their relevance and applicability in urban contexts in Colombia: rainwater harvesting tanks, green roofs, floodable tree pits, and permeable pavements. The methodology was based on a review of technical and regulatory literature, along with an analysis of design criteria specific to each system. Predimensioning procedures were developed and complemented with practical exercises that facilitate the understanding of basic hydraulic functioning and its application in real scenarios. The results of this work are reflected in the consolidation of clear guidelines on design principles, environmental benefits, and construction considerations, providing useful tools for planning and decision-making in the early stages of urban design. Overall, this handbook promotes the integration of SUDS as strategies that strengthen urban resilience, help mitigate flooding risks, and improve rainwater management in the face of climate change challenges.
