Evaluación y comparación de un diseño de un sistema de alcantarillado pluvial convencional y un sistema de drenaje mediante tecnología SUDS, para el sector de Mochuelo Bajo en la localidad de ciudad Bolívar en Bogotá D.C.

Due to the exponential growth of cities and the increase of non-permeable hard areas and runoff volumes, accompanied by climate change, it is important to implement systems that mitigate the problems associated with the poor performance of conventional storm sewers when extreme events occur. This leads to the implementation of non-conventional alternative systems that, through nature-based solutions, mitigate and delay storm peaks, thus avoiding the collapse of sewerage networks. Similarly, it has been proven in other implementation cases that the application of Sustainable Urban Drainage Systems not only leads to a technical benefit, but also, since most of them are accompanied by the implementation of green areas and urban renewal, there is an improvement in the conductivity of fauna species, an increase in vegetation cover and an improvement in the quality of life of the benefited population. The sector of Mochuelo Bajo in the locality of Ciudad Bolivar, in the city of Bogota, is taken as a case study, based on the Consulting Contract No. Uaesp-752-2020, whose purpose is "Preparation of detailed studies and designs to complete 100% of the sanitary and storm sewerage networks of Mochuelo Alto and Mochuelo Bajo and the optimization of the wastewater plant of both sectors, in the locality of Ciudad Bolivar". This study seeks to solve the problem of rainwater management in the sector of Mochuelo Bajo, which currently generates flooding and damming of both rainwater and wastewater in different sectors of the area, designing a conventional storm sewer system and a system where SUDS are implemented. Based on the designs, a technical, economic, environmental and operational comparison of the systems was made in order to identify which one is more adequate for the study area, taking into account that both designs provide a solution to the problem. The results showed that the implementation of SUDS typologies are technically, environmentally and socially more effective than the implementation of a purely conventional sewerage system; however, their implementation is limited to the availability of areas, urban planning and economic resources, so that, for the specific case of study, where urban development has been carried out informally and there is no adequate urban planning, this is not the most efficient option. The implementation of SUDS implies an evaluation of specific initial conditions for their use, so that, under ideal urban development conditions, it is advisable to evaluate the applicability of this type of system, since it offers important benefits in environmental and social factors
