Methods and systems are provided for injecting water stored in a water reservoir at a plurality of locations in an engine system, including directly into engine cylinders, upstream of a turbocharger turbine, and at an exhaust manifold, and controlling a water level of the water reservoir. In one example, a method may include supplying the water stored in the water reservoir to one or more of a water injection system, a windshield wiper system, an engine coolant system, and a drinking water system based on water supply conditions and responsive to engine operating conditions. When the water level is low (e.g., below a threshold), supply to the water injection system may be prioritized.
