Wastewater is effectively disinfected while reducing both chlorine consumption and more particularly the levels of residual chlorine discharged from the wastewater treatment plant. The wastewater is first contacted with a sufficient amount of chlorine to satisfy the chlorine demand and to obtain as low a residual level of chlorine as possible. After the chlorine demand has been satisfied, the wastewater is disinfected with an effective amount of 2,2-dibromo-3 -nitrilopropionmaide. 37,413-F
