“…Se estima que en la región apenas el 33% de la población se conecta a los 48 meses de la puesta en marcha del sistema (Sturzenegger, Vidal, & Martinez, 2020). En el caso de Paraguay, si bien no existe una medición nacional sistemática que permita dimensionar la problemática, un ejemplo es el sistema de alcantarillado sanitario y tratamiento de aguas residuales de Coronel Oviedo, en donde la cantidad de aguas residuales tratada es muy inferior a la de su capacidad de diseño (Cuppens, Smets, & Wyseure, 2013). Contar con un alto nivel de conexiones efectivas no solo es necesario en el futuro inmediato, posterior a la construcción, sino también a lo largo de la vida útil de la infraestructura a la par del crecimiento de la población del área de influencia del proyecto.…”

El presente documento tiene como objetivo realizar un análisis exhaustivo de la situación de la prestación de los servicios de agua potable y saneamiento en Paraguay, mediante la verificación de los principales retos con relación a los siguientes pilares: i) oferta y eficiencia de infraestructura sanitaria; ii) gestión de servicios; iii) gestión institucional; y iv) gestión integrada de los recursos hídricos, y proponer medidas o acciones prácticas que sirvan de guía a las instituciones sectoriales y a los operadores de agua y saneamiento para establecer una hoja de ruta hacia una prestación de servicios más eficiente, sostenible y resiliente.

“…In developing countries, sewered treatment infrastructure failure may not necessarily be attributed to age, but is most likely due to inadequate implementation strategies (Cuppens et al, 2013;IWA, 2006). Implementation of sewered infrastructure in developing countries puts more emphasis on technology than on the process of solution identification, technology transfer and capacity-building mechanisms, which are crucial factors for the long-term success of sanitation infrastructure (Murphy et al, 2009).…”

“…Even when new infrastructure are constructed, too little attention is given to why existing ones failed and/or are not performing well. The stories behind these poorly functioning facilities hardly reach decision-makers, researchers and consultants involved in sanitation (Cuppens et al, 2013).…”

“…The retrospective approach aims to look back to the history of related infrastructure, including the initial planning and design processes, to understand the current failing status. The interdisciplinary approach reflects on the necessity of understanding the influence of PSEP on sanitation technological solutions and management (see Chapter 4) (Cuppens et al, 2013;Tiberghien et al, 2011).…”

Technological system 'We are stuck with technology when what we really want is just stuff that works' Douglas Adams 5.1 INTRODUCTION ReGenSan technology system (TeS) refers to a functional and standardized infrastructure across the sanitation service chain (SSC) that is seamlessly networked (i.e. conventional/non-conventional sewerage) and loosely networked (i.e. non-sewered systems), designed to deliver reliable safely-managed sanitation infrastructure aimed at access expansion and service improvement (Kaminsky &

“…According to research, drainage systems respond differently to expected climatic changes depending on the location [10][11][12][13][14]. To improve the current infrastructure and create new stormwater systems, local decision makers must consider the consequences of these circumstances for managing stormwater and floodplains on a site-specific basis [15][16][17]. Urban stormwater management and flood mitigation are receiving more attention in sensitive areas, especially in emerging nations like India.…”

Over the past several decades, urbanisation has spread rapidly over the globe. Research on the viability of urban stormwater drainage systems and the search for solutions to the related problems constitute an important prerequisite for their sustainability evaluation. The Government of India’s sub-committee for the development of “National sustainable habitat parameters on urban stormwater management” has proposed twenty key indices to promote and monitor the sustainable urban stormwater management paradigm. Their evaluation may be taken up at various stages of development, including planning/design, execution, post-operation audits, impact assessment, etc. Eleven of these sustainability indices, including the “Natural drainage system index (NDSI), the Drainage coverage (constructed) index (DCI), the Permeability Index (PI), Water bodies rejuvenation index (WBRI), Water body vulnerability index (WBVI), Water logging index (WLI), Area vulnerability index (AWI), Stormwater discharge quality index (SWDQI), and Rainfall intensity index (RII)” were evaluated for three Tier I cities (Delhi, Mumbai, and Chennai) and three Tier II cities (Varanasi, Chandigarh, and Roorkee) in India based on the available data for 2010 as the datum year and 2020 as the test year. All the considered cities serve as economically and institutionally important urban centres, fall in different climatic zones, and are distributed in two major categories based on the scale of development and population density. All the indices enumerated individually fell within the range of 0 to 1, the two extremities of the sustainability range. Further, ranking of various indices was done employing the Analytical Hierarchy Process, and after deriving the weights for each, aggregation of all these indices was performed to yield an “Overall sustainability index” for each city. Different values were demonstrated along the sustainability scale for all the cities based on performance with regard to various constituent indices in a standalone mode and their interplay in an aggregated mode. The findings are expected to provide important insights to meet the goal of the developing sustainable urban drainage systems (SuDSs).
