Chehlbazeh local wastewater treatment plant of Mashhad is one of the most advanced membrane wastewater treatment plants in the country, which was built using advanced MBR technology on a land with an area of approximately 2500 square meters at the end of Mashhad Student Street and on the outskirts of Kal Chehlbazeh.

The average capacity of this treatment plant, which is also considered the largest local treatment plant in the country, is more than 50 liters per second (4320 cubic meters per day), which provides the wastewater necessary to irrigate large areas of Mashhad city with very high quality.

Mashhad’s Chel Baze local has been used.
