Abfa Chief Reiterates Need to Promote Greywater Use

The deficit of groundwater reserves has surpassed 130 billion cubic meters, director of the National Water and Wastewater Engineering Company of Iran (Abfa) said.
“Annual precipitation is in the region of 400 billion cubic meters, of which 70% or 280 bcm evaporates,” Qasem Taqizadeh Khamesi was quoted as saying by IRNA Sunday.
Due to its geographical proximity, 1% of the country’s area receives 1,000 millimeters of rain and snowfall. This is while annual precipitation in 28% of the land is less than 100 millimeters per year, he said.
Given the limited (fresh) water resources in many countries, people are forced to use the precious resource prudently by adopting a variety of ways, one of which is tapping into unconventional sources like greywater.
