Abstract Infrastructure deterioration threatens urban water security and the pursuit of Sustainable Development Goal 6 (SDG 6, “water for all”). One billion urban residents worldwide already face intermittent piped water access, making their public water supply unreliable and unequal. Thus, effective investments in water infrastructure improvements are critical. In a recent WRR paper, Jeuland et al. (2023, https://doi.org/10.1029/2022WR033897) evaluate the impacts of a large infrastructure improvement project on various water security metrics and assess the challenges of such an investigation. They apply a rigorous difference-in-difference approach to data from a US$275 million investment in upgrades to water supply and sewage networks in the Zarqa governorate in arid Jordan, analyzing its effects on households, businesses, farms, and the water utility. The authors find a range of moderate improvements to water access and re-use metrics, including a significant reduction in reported shortages. Key water security indicators related to access intermittency, however, such as the supply duration per day and the expenditure on water deliveries by tanker trucks, saw little to no improvement. The findings reveal that the efforts required to overcome the insecurity and inequity of intermittent public water supply systems might be considerably larger than expected. This suggests an urgent need to further enhance both the accuracy of impact evaluation methods and the effectiveness of infrastructure investments to support the pursuit of SDG 6.
