This paper assesses urban water as an alternative freshwater resource for irrigation in the Bengal delta, Bangladesh, where coastal plains face irrigation water shortages. Using the FAO AquaCrop model, it was found that 7.4 million m3 of irrigation water is needed for Boro rice during the dry season, while over 8.2 million m3 of urban water is generated. Mismatches between demand and supply occurred in February and March, suggesting a need for water storage capacities and policy changes to facilitate urban water reuse infrastructure.
