This data compares municipal water charges for a number of reasonably wealthy global cities, with GDP per capita shown for context. Its purpose is to benchmark the price of municipal water for cities in Saudi Arabia. The data demonstrates that water charges in Saudi Arabia are significantly lower than for all other cases shown, despite its GDP per capita being comparable. This comparison is used to support the case that water charges in Saudi Arabia are too low and should be increased. The data is taken from work already published, with the addition of the figures for Saudi Arabia.
