Northern Sewage Collection Network Is Lagging Behind

An estimated 130 million cubic meters of wastewater is produced by households in the northern Mazandaran Province, of which less than 20 mcm is recycled and the rest flows into the Caspian Sea or seeps in the ground, head of the provincial water and Wastewater Company said.
“On average 50% of sewage is treated in the provinces, but Mazandaran is far behind due to underdeveloped infrastructure,” Majid Abdollahi was quoted as saying by IRNA.
Annual water consumption in the household sector in the major northern tourist hub is about 150 mcm producing 130 mcm of effluent, he said. Not reclaiming the massive volume is a big economic and environmental loss for the region with adverse effects for the water tables.
“Close to 90% of water demand in the region is met with the help of underground resources and failing to efficiently treat wastewater will contaminate the underground water reserves and endanger a region of 3.2 million inhabitants.”
