Does the sewage treatment plant belong to a public institution?

First of all, I can tell you for sure that the sewage treatment plant recruits people independently. The person recruited must not be a career establishment, but a supernumerary contract worker. The treatment is managed according to the staffing of the enterprise, and there is no staffing. There are temporary workers, so it is better not to go. The treatment is only the local minimum wage.

Secondly, the sewage treatment plant itself may be a public institution, but it is largely a self-supporting enterprise. It is actually an enterprise. This kind of unit recruits people or contracts, and there is no preparation at all. Of course, it is better than ordinary local enterprises.
