    Aguas grises: Aportes de cedeus sobre tecnologías de tratamiento, percepción social y desarrollo de normativas en chile – Parte 1
    (Centro de Desarrollo Urbano Sustentable, 2024) Gallardo, Carlos; Vargas, Ignacio; Gironás, Jorge; Molinos, María; Bertoli, Rodolfo; CEDEUS (Chile)
    Actualmente en Chile el ciclo urbano del agua se basa principalmente en sistemas convencionales centralizados de suministro y tratamiento de agua. Uno de los principales desafíos para las ciudades chilenas es implementar el uso de fuentes alternativas de agua. Un ejemplo de lo anterior es el reúso de aguas grises recuperadas a través de sistemas de tratamientos descentralizados energéticamente sustentables. Dado que las aguas grises corresponden aproximadamente a un 60% de las aguas usadas en un hogar, su tratamiento y reúso seguro emergen como una oportunidad relevante para el desarrollo sustentable de las ciudades chilenas.

    Flexible Instruments to Address Water Security in the Context of Climate Uncertainty: A Case Study of Option Contracts in a Chilean River Basin
    (ASCE-AMER SOC CIVIL ENGINEERS, 2025) Ávila, Antonia; Vicuña, Sebastián; Gironás, Jorge; Melo, Oscar; Rivera, Daniela; Molinos, María
    Climate change is causing widespread extreme weather events around the world, affecting food and water security. One example is Chile, which is facing the longest drought in its history. To cope with this situation, adaptation measures such as option contracts have been explored. This type of contract allows the temporary transfer of water from one user to another, depending on weather conditions, with monetary compensation for the users who give up the water. Using the Aconcagua River basin as a case study, it was possible to evaluate the effectiveness of these contracts to mitigate the impact of drought on human consumption in a context of climatic uncertainty. The results indicate that the contract is activated between 0 and 49 times depending on the scenario and that the water supply of the water utility is increased. In conclusion, it is found that option contracts allow mitigating future water scarcity, reducing unsatisfied demand, and improving the water security of the affected populations.

    Reúso de agua urbana domiciliaria
    (Centro de Desarrollo Urbano Sustentable, 2023) Gallardo, Carlos; Rivera, Javier; Amaris, Gloria; Vargas, Ignacio; Gironás, Jorge; Molinos, María; Bertoli, Rodolfo; CEDEUS (Chile)
    El crecimiento de la población urbana, junto con el cambio climático, está estresando las fuentes convencionales de agua dulce. Gran parte del agua que se consume domiciliariamente, tras su tratamiento en plantas de aguas residuales, se desecha sin darle otros usos. Nuevas estrategias de gestión de las aguas residuales, como su reúso, pueden generar fuentes alternativas de recursos hídricos. Las alternativas de reúso deben considerar el tipo de agua de origen y su uso proyectado acorde a la normativa y aceptabilidad pública. La reutilización de aguas domiciliarias urbanas puede significar reducciones en la huella de carbono por el menor consumo energético en transporte y operación asociado al tratamiento convencional de aguas residuales.

    Towards a Drought Monitoring, Tracking, and Management Platform Based on Quantitative Indices
    (2025) Gironás, Jorge; Núñez, Marialina; Vicuña, Sebastián; Aedo, Sebastián; Morales, David; Vargas, Javier; Guzmán, Juan de Dios; Suárez, Francisco
    Drought is a complex phenomenon that affects the development and use of the country’s water resources. Characterization through indices is critical in planning, management, and decision-making to mitigate the effects of drought, mainly when these are implemented in online platforms for monitoring, warning, and tracking the phenomenon. These tools serve as a basis for implementing a set of measures focused on the short, medium, and long term, oriented to different audiences, and with differentiation of procedures and entities involved depending on the case. This work proposes the technical basis for elaborating preventive drought monitoring in Chile through a visualization platform. Based on a comparative analysis of international tools and the results of a consultation with experts, the relevant characteristics of a system for drought monitoring, follow-up, and management based on standardized drought indexes are analyzed. It is concluded that such a platform should consider multiple drought indices with different levels of severity for their classification. These indices should be automatically calculated using as much information as possible, both from national and international sources, from in-situ gauges as well as from satellite and remote sensing products, and even obtained from modeling. On the other hand, the visualization should be simple, straightforward, and flexible, and the information delivered should provide information on the manifestation of drought in the territory and its short-term forecast.
