Undergraduate course: those who have been engaged in water supply and drainage work for half a year after graduation can evaluate their work permits, and they can take the basic examination of water supply and drainage registration (public foundation+professional foundation) after working for one year; It takes about 3-4 years for the intermediate title to apply for a work permit before it can be evaluated. You must publish 1-2 papers, and you must pass the English test for technical title B; After passing the basic registration examination, you can be qualified for the professional examination only after you have been engaged in water supply and drainage for about 6 years. Senior engineers must be 10 years later with intermediate titles, and must pass computer and CAD exams to publish papers, and so on.

If you are a graduate student, you can be a helper directly. Three years later, you will evaluate intermediate titles and publish 1-2 papers. If you pass CET-6, you can skip the English Test for Science and Technology B title. Graduate students are eligible to take the basic registration examination, and so are others.

I hope it helps you!
