Analysis and Suggestion of Water Source Safety Guarantee of Danjiangkou Reservoir

Danjiangkou Reservoir is the water source for the Middle Route of South-to-North Water Transfer Project, as well as an important drinking water source of Hubei Province. In 2021, Danjiangkou Reservoir has a good safety guarantee situation on the whole. However, there exists some problems such as imperfect water source protection and management mechanism, hidden danger of water quality and inadequate funding investment mechanism. In specific, the hidden dangers of water quality include imperfect isolation facilities, water resource management information system, environmental pollution prevention and control measures and difficult management of water-level fluctuation zone. In this paper, suggestions for water source safety guarantee construction of Danjiangkou Reservoir future are proposed: (1) improve the supervision and management mechanism and the protection and management mechanism of drinking water source, strictly enforce the daily management, supervision and inspection of the water source; (2) strengthen the supervision of water quality risks, carry out the construction of ecological isolation zones of water sources, improve the management system of water-level-fall zones and strengthen the construction of information systems and traffic protection facilities; (3) establish a long-term and stable fund guarantee mechanism, a sound investment and financing system, a special transfer payment mechanism for water source of the middle route of the South-to-North Water Diversion Project and a green development fund for Danjiangkou Reservoir water source area; (4) promote the construction of emergency standby water sources.
