Studying and obtaining permits for the construction of an injection site in 2019 with the aim of non-surface wastewater disposal, it was initially launched and started operating by digging 2 injection wells in a land area of 300 hectares. Now, after 6 years, with the help of the knowledge and expertise of the workers, 11 wastewater injection wells have been launched at this site. With an average of 12 liters per second for each well, approximately 130 liters of wastewater from the Golestan Salt Factory outlet are injected every second to a depth of 800 to 1000 meters in accordance with environmental requirements and guidelines to prevent any environmental hazards. Today, only 3 countries use industrial wastewater injection technology, and after the United States and Japan, Iran is the third country to benefit from this technology thanks to the efforts of local experts in the province. Due to its complexity and high sensitivity, the wastewater injection process is carried out accurately and regularly 24 hours a day, without interruption, with equipment such as high-pressure pumps, pressure piping systems, high-pressure industrial valves, precision instrumentation systems, and control sensors. The infrastructure required for the construction of the injection site includes 17 kilometers of high-voltage power poles to supply electricity to the site, 7 kilometers of internal site infrastructure and roads, 10 kilometers of concrete channels and 16-inch pipelines to transport wastewater from the factory to the site, landscaping and concreting of the well platform, 6 kilometers of 8-inch lines to supply well feed, and diesel generators to provide emergency power in times of nationwide power outages, etc.
Injection site
The Golestan Shorabeh Yad Factory wastewater injection site began operating in 2019 with the aim of non-surface wastewater disposal and initially consisted of 2 wells on an area of 300 hectares. Now, with the efforts of experts, the number of wells has reached 11, each of which injects an average of 12 liters per second, and a total of about 130 liters of wastewater per second is injected to a depth of 800 to 1000 meters and according to environmental requirements. Iran is the third country to benefit from this technology after the United States and Japan. This 24-hour process is carried out with advanced equipment such as high-pressure pumps, piping systems, and precision instruments. The site's infrastructure includes 17 kilometers of high-voltage electricity, 7 kilometers of road construction, 10 kilometers of 16-inch sewage transfer canals and pipes, landscaping, 6 kilometers of 8-inch lines to supply wells with feed, and a diesel generator for emergency power.
