about us

Kayson Water and Environment Company was established in 2017. This formation followed structural and management changes within the Kayson Group, with the aim of creating a specialized holding company. This move was a natural progression, transforming Kayson Company’s Water and Wastewater Group into an independent entity.

However, the history of Kayson’s involvement in the water sector stretches back much further, to 1975, the year the company was founded. Kayson’s inaugural executive project, the Fumanat Irrigation and Drainage Network, marked the company’s entry into Iran’s water industry. Subsequently, through projects such as the Hamidieh-Quds Plain Irrigation and Drainage Network, the Poldasht Diversion Dam and its Associated Irrigation and Drainage Network, and the Sattar Khan (Ahar) Earthen Dam, Kayson solidified its position as a major player in this field.

In 2005, the company significantly expanded its operational scope by undertaking the Hamedan Pipejacking project and introducing polymer concrete pipe production technology from Polymer Concrete Pipe Company (a Kayson subsidiary). Kayson also successfully completed the Upper and Lower Dams of the Siyah Bishe Pumped Storage Power Plant, notable as the nation’s first concrete-faced rockfill dams. This achievement earned them a crystal statuette at the National Award for the Best Project in Iran.

To address the country’s pressing needs and conserve water resources, the company took a pivotal step by broadening its service portfolio in water and wastewater. This expansion included the design and construction projects for wastewater treatment plants in the cities of Ahwaz, Mashhad, and Bandar Anzali.

Over the last decade, driven by the growing demand for new water resources, Kayson Water and Environment Company has played a crucial role in executing water desalination projects. The monumental Bandar Abbas water desalination project, followed by the Chabahar project, established the company as the largest contractor in this sector nationwide.

Furthermore, projects like the Qarasu-Zarringol Irrigation and Drainage Network and the Hybrid Cooling Tower for the Isfahan North Refinery exemplify the company’s commitment to optimizing water consumption and reducing waste of the nation’s precious water resources.

Thanks to its accumulated experience, application of cutting-edge technical knowledge, and active participation in national infrastructure projects, Kayson Water and Environment Company has evolved into one of the most capable engineering and contracting firms in Iran’s water sector.

Kayson Water and Environment Company specializes in the design, procurement, execution, supervision, installation, commissioning, and management of construction projects.
