The minimum three-level environmental protection professional contracting qualification and safety production license are required. The above two items are handled at the construction committee. If you want to do a water treatment project, you must have it.
If you are doing a water treatment operation project, you need to apply for operation qualifications and apply for it at the State Environmental Protection Administration.
If you are doing a small water treatment project, the cost is less than 3 million. If the construction party does not have qualification requirements, you can also do it.
The above qualifications are not easy to obtain, especially in Beijing, which requires more professional certificates, such as construction engineers (level one, level two), engineers (intermediate, advanced), and operational qualifications. Only professional training and certificates can be obtained.
