This paper summarizes the situation facing water supply and drainage science and engineering specialty, points out that the characteristic specialty construction must consider the professional certification and assessment, the new challenge of ability training, the requirement of emerging engineering education, innovative education, "six excellence and a top-notch" program 2.0. The main contents include cultivation system, teaching staff, knowledge system, curriculum construction, teaching procedure, practice and training. The training and practice education of water supply and drainage engineering ability was the most important bridge between the special theoretical knowledge and innovation ability, and proposed the high quality personal training system, which was theory, virtual simulation, training, innovation, and explained the practical cases of characteristic construction for water supply and drainage science and engineering specialty.
