According to the construction practice of water and wastewater engineering,the paper deeply analysis the construction characters on high building water and wastewater engineering, introduce the construction methods and key points and propose the construction management methods such as "keep importance on pre-set of pipe construction","the standardized room of pipe construction".

With the teaching practice of water and wastewater specialty,the paper points out the difficulties of the university graduation project work faced and analyzes the causes of the poor quality of graduation project.

This paper makes a summary about the teaching expences of the course of water supply and sewerage engineering CAD.

The structure of the courseware and the techniques for interface design and making are also discussed in this paper which provides technique support for the teaching innovation for water and wastewater CAD.
