PROBLEM TO BE SOLVED: To purify water, by preventing stagnation of the water of a recessed part secluded from the shore of a river. SOLUTION: This stagnation preventive method includes a step of arranging a conduit 3 so that one end part is positioned in a water flow of the river 1 and the other end part is positioned in the secluded part of the recessed part 2 recessed from the shore of the river 1, and a step of sending this water into the innermost part of the recessed part 2 via the conduit 3 by introducing the water of the river 1 from one end part of the conduit 3 by using dynamic pressure of the water flow of the river 1.
