Effective communication to citizens is of prime importance during public health crises involving water. This paper takes a sequential mixed method approach to the problem of communicating drinking water risks prevention of exposure to health risks in cities, related to SDG 6: clean water and sanitation.

The expansion and operation of water supply systems under growing demands, hydrologic variability, and water scarcity requires strategic decisions on supply sources for reducing and improving reliability and flexibility. This paper provides an integrated framework to optimize water supply system expansions using dynamic programming and combining short and long term water supply source optimization using quadratic programming. This relates to SDG 6.

An agent-based model is created using data for household characteristics and outdoor water use to calculate water demands. This model represents utility response to water shortages to enact residential restrictions. The agent-based model is coupled with reservoir simulation for a case study, and results are compared to historic data. Sustainability of water policies is evaluated for climate scenarios created using a stochastic reconstruction framework. This is related to SDG 6.

Urban source separation infrastructure systems have a promising potential for a more sustainable management of household food waste and wastewaters. A renewed trend of larger implementations of pilot areas with such systems is currently emerging in Northern Europe. This study investigates the drivers behind the decision of stakeholders to implement source separation systems as well as the importance of the previously existing pilot areas in the decision-making process.

This paper discusses the CO2 footprint of California’s drought during 2012–2014. The authors show that California drought significantly increased CO2 emissions of the energy sector by around 22 million metric tons, indicating 33% increase in the annual CO2 emissions compared to pre-drought conditions. They argue that CO2 emission of climate extremes deserve more attention, because their cumulative impacts on CO2 emissions are staggering. Most countries, including the United States, do not have a comprehensive a nationwide energy-water plan to minimize their CO2 emissions, therefore the authors argue that developing a national water-energy plan under a changing climate should be prioritized in the coming years.

An international review of stormwater regulation and practices, especially for low-exposure, landscape irrigation schemes in urban environments, was undertaken with a view to identifying what could be used in Alberta, Canada. A general lack of clear guidance and regulation to manage stormwater quality and potential public health risks was identified, which could be hindering the uptake of stormwater schemes generally.This related to SDG6 and SDG 11.

Cities are strongly dependent on infrastructures providing essential services, namely Lifeline Systems (LS) that support societal functions, safety, economic prosperity and quality of life. The operation of LS in ordinary conditions as well as after disasters is crucial. The main aim of the paper is to define a System Dynamic Model (SDM) to assess the evolution of resilience of a drinking water supply system in case of natural disasters, with particular attention to the role of both ‘structural’ and ‘non-structural’ parameters drawing on the L’Aquila (Italy) earthquake as a case study.

Water recycling schemes are a viable solution to limitations on water supply and yet public acceptance of these schemes is low. Advancing SDGs 6, 11 and 12, research was conducted in three metropolitan areas in the US to assess basic perceptions of treated wastewater occurrence and its acceptance in the public water supply. De facto reuse occurs at rates across the three cities higher than what is perceived. Roughly 25% of respondents perceive de facto reuse to occur in their home tap water. Respondents who perceived de facto reuse to occur at their tap were ten times more likely to have a high level of acceptance.

The study of resilience in the face of large physical and climatic change has emerged as an important area of research. But while the physical variables under study are easily identified, the notion of resilience itself remains nebulous. This poses a special challenge to water security in cities. The tensions are resolved when resilience is conceived of as a teleological concept that relates to the desired futures of the community.This study shows an empirical way to achieve this by using narrative analysis on the case of water security. Such a teleological concept can be used to resolve tensions pointed out earlier and give practical insights, related to SDG 6 and 11.

Shortages of freshwater have become a serious issue in many regions around the world, partly due to rapid urbanisation and climate change. Sustainable city development should consider minimising water use by those people living in cities and urban areas. The purpose of this paper is to improve our understanding of water-use behaviour and to reliably predict water use, highly relevant to SDG 6 and 11.
