Abstract:Supervision and management of water project construction quality and safety is an important responsibility of the water authority, which is of great significance for ensuring the quality and safety of project construction and reducing accidents and injuries. Under the background of deepening the market-oriented reform process in the field of engineering sector, the water management concept of "joint eforts" from President Xi, provides a fundamental basis for strengthening the supervision and management of water engineering quality and safety. Promote the water authority to introduce multiple market entities to participate in the supervision of water project quality and safety, and build a new supervision mechanism of "government-led, market operation, social participation, and multiple co-improvement" based on the theoretical framework of collaborative governance.
