A portable water treatment unit is provided for purifying contaminated water, especially in the aftermath of a natural disaster that compromises a region's water supply. The treatment unit is configured to treat water drawn into the unit. The treatment unit comprises an inlet connected to a pump. The pump outlet is connected to a solid separator for removing larger particles such as sand and silt. A series of filters is connected to the pump outlet, the filters being arranged from coarsest to finest. The filters remove smaller particles from the water. The water from the filters eventually flows into an ultraviolet light disinfection unit configured to purify water by emitting ultraviolet light thereon. An outlet of the UV light disinfection unit is configured to expel purified water for drinking and other uses. Pressure gages are provided for monitoring the pressure drops across the filters. A flow meter is provided for monitoring the flow into the UV light disinfection unit, to ensure adequate UV disinfection. The entire treatment unit is preferably provided within a cart with wheels.
