The utility model relates to the technical field of pipeline water leakage monitoring devices, in particular to pipeline water leakage monitoring test paper. The pipeline water leakage monitoring testpaper comprises a test paper body, and the test paper body is used for wrapping a pipe joint; Wherein the test strip body comprises a permeable membrane, an anhydrous cupric sulfate coating and a transparent waterproof membrane which are sequentially attached together, the anhydrous cupric sulfate coating is located between the permeable membrane and the transparent waterproof membrane, and the permeable membrane is attached to the outer surface of the pipe joint. According to the pipeline water leakage monitoring test paper provided by the utility model, the principle that the anhydrous cupric sulfate turns blue when meeting water is utilized, so that the water leakage position in the pipeline can be quickly observed, timely maintenance is facilitated, and the working efficiency is improved.
