Description
The project was aimed at supplying healthy and safe drinking water (1500 Liter/s) to Mazandaran Province, especially the cities of Babol, Babolsar, Amirkola, Fereydunkenar, and Kalleh Bast, and the villages located along the pipeline route.
The project consists of a water treatment facility, water transmission pipelines, reservoir water transmission pipelines, and pumping stations.
Alborz Dam- Tolout water transmission pipeline was aimed at supplying water to Mazandaran Group A cities (phase 1). The pipeline has a length of 50 km and is comprised of 1000- and 1200- mm pipes. This project was implemented by Iran Ertebat Engineering Company.
All the operations were carried out in close proximity to forests, mountains, and rural roads.
