Water Rationing in Tehran a Last Resort Possibility

Water rationing is among the various scenarios on agenda to contain the water crisis in metropolises such as Tehran in the upcoming summer, though the authorities pledge that it will be a last resort.  
The continuous decline in precipitation levels over the years peaked this year and registered the lowest amount of rain in about 50 years. Although decent springtime rainfall offered a brief reprieve and partly revived several desiccated wetlands, it was not sufficient to tackle the water shortage completely, Zist Online reported.
