Abstract:

Constructing a water quality safety guarantee system that aligns with national strategic water source zones constitutes an essential part of the operation and management of the South-to-North Water Diversion Middle Route Project in the new era. This paper proposes the establishment conception of four major systems—monitoring station network, water quality monitoring, risk prevention, and technological support—based on the new requirements and objectives for water quality monitoring in the Danjiangkou Reservoir and its upstream basin. We detail the fundamental concepts and elements of these systems. The four systems aim to ensure the sustainable northward flow of clean water by enhancing the water quality monitoring framework through comprehensive coverage, timely alerts, advanced intelligence, three-dimensional perception, focused monitoring, and scientific research.

Key words: Middle Route Project of South-to-North Water Diversion, Danjiangkou Reservoir, water quality monitoring system, water quality safety guarantee
