The platform of innovative practice will effectively promote practical training and improve the training quality of innovative talents. Taking the water supply and drainage science and engineering for example, this paper introduces the ideas to building innovative practice platform based on the operation mechanism and safeguards of platform, and analyzes the practice target, and the main results achieved with the experience. Multi-level and multi-disciplinary platform for innovative practices can further improve the innovation ability and practical ability of undergraduates, and can ensure the sustainable development of the undergraduate students’scientific research.
