This project is located at a Sinopec gas extraction site in Chongqing. The units have been in use since 2018.
According to site management and workers, the toilets are practical and durable. They have been relocated between different working areas multiple times and continued to operate normally after each move.
The project has involved nearly 300 units, with some units having been in service for almost eight years without repair. Based on the continued use of the existing units, another batch is planned for procurement by the end of 2026.
