Sustainability Assessment of Sanitation Indicators in the PCJ Watersheds 2020-2035 Plan

Abstract Understanding how variables that integrate sustainability indexes behave is essential due to the limitation of natural resources under a growing demand. Based on case study and exploratory research techniques, this paper aimed to analyze the levels of collected and treated wastewater in the PCJ Basins Water Resources Plan for the 2020-35 period. We sought to validate the indicators based on Gibson’s sustainability principles, relating them to the 6.2 and 6.3 targets of the Sustainable Development Goal (SDG) 6. It was concluded that the indicators are important to evaluate processes to achieve SDG 6. However, the indicators have flaws and can mask important information, preventing more assertive decision making. The target to achieve the 2035 reference scenario was found to be valid for four of Gibson’s sustainability principles.
