“…These papers cover a large number of countries (Spain, France, Jordan, Australia, Bangladesh, Brazil, Lithuania, Peru, Poland, Russia, Serbia, Tanzania, Zambia, Zimbabwe, Colombia, India and Unites States of America). Some papers deal with the impact of water metering on residential water use (i.e., [46][47][48]), while others consider pricing policies (i.e., [49,50]), non-price policies (i.e., [51,52]) or the performance of water services (i.e., [53,54]). All selected papers contribute to a better understanding of residential water use, and they provide relevant results for policy-makers in charge of water management.…”

The aim of this Special Issue is to gather evidence on the impact of price policies (PP) and non-price policies (NPP) in shaping residential water use in a context of increased water scarcity. Indeed, a large body of the empirical economic literature on residential water demand has been devoted to measuring the impact of PP (water price increases, use of block rate pricing or peak pricing, etc.). The consensus is that the residential water demand is inelastic with respect to water price, but not perfectly. Given the low water price elasticity, pricing schemes may not always be effective tools for modifying household water behaviors. This is puzzling since increasing the water price is still viewed by public authorities as the most direct economic tool for inducing water conservation behaviors. Additional evidence regarding the use of PP in shaping residential water use is then required. More recently, it has been argued that residential consumers may react to NPP, such as water conservation programs, education campaigns, or smart metering. NPP are based on the idea that residential water users can implement strategies that will result in water savings via changing their individual behaviors. Feedback information based on smart water metering is an example of approach used by some water utilities. There are still large gaps in the knowledge on the residential water demand, and in particular on the impact of PP and NPP on residential water use, household water affordability and water service performance. These topics are addressed in this Special Issue “Advances in the Economic Analysis of Residential Water Use”.

“…The regression results were assessed through residue distribution analysis, as well as the variance, the presence of outliers and serial correlation ( Hyndman and Athanasopoulos, 2018 ). The Kruskal-Wallis H test was used to analyze the variation of residential water consumption considering the different types of buildings (houses, apartment buildings and condominiums), since the assumptions required by the ANOVA test were not achieved ( Vargas et al., 2018 ). For the analysis of household location data, spatial statistics techniques were used, presented in the form of indexes that measure the spatial association.…”

This article aims to assess the impact of coronavirus (COVID-19) spread-prevention actions on water consumption, based on a case study in Joinville, Southern Brazil. Residential water consumption data, obtained through telemetry in two periods (before and after a governmental action imposing quarantine and social isolation), were analyzed. Complementarily, the analyses were also applied to the commercial, industrial and public consumption categories. For the analysis, Wilcoxon and Kruskal-Wallis non-parametric tests were applied and Prais-Winsten regression models were adjusted. The results of the Wilcoxon test show that there are significant differences between the analyzed periods, indicating a water consumption drop in the commercial, industrial and public categories, and an increase in the residential category. The regression model results confirm the effect of the restrictive actions in reducing consumption in non-residential categories. The results also indicate an increase in water consumption, which was steeper in apartment buildings than in houses, whether isolated or grouped in condominiums. A weak association was found between the variation in water consumption and the spatial distribution of buildings. Understanding water consumption related aspects is important to gather essential information to ensure the urban water supply system is resilient in a pandemic situation.

“…For example, Grafton et al (2011) found that price-based approaches encouraged economic efficiency and the volumetric water pricing was one of the most effective drivers to control household water consumption. Vargas et al (2018) addressed affordability as a determinant of residential water consumption in the city of Bogota, Colombia. In 2012, the local government executed a program called 'lifeline' to provide easy water access to lower income households for free.…”

Analyzing the Residential Water Consumption Patterns of the City of Toronto and the Relationship With Demographic Variables

The aim of the thesis was to understand residential water usage in Toronto from 2001 to 2016 and to explore demographic and economic variables that might have affected use. Data were aggregated at the ward level and analyzed by multiple regression. The model explains that wards with high average household income use more water per capita. Water exhibited price elasticity, per capita water use decreased as price increased, but more so in low income wards than high income wards. Average household size had a positive effect on per capita water use; larger households use more water, not only in total, but per capita. Annual rainfall had a negative effect on per capita water use, perhaps due to decreased water demand for lawns and gardens. Interestingly, the percent immigrant had a negative effect on water use which suggests a stronger ethos of water conservation among newer Canadians.
