Urban parks enhance livability but consume significant water for irrigation. This study proposes a linear programming model to optimize allocation from diverse sources (groundwater, rainwater, runoff, treated wastewater, greywater, potable water) and design storage/treatment capacities, factoring in precipitation, quality, vegetation needs, and park area. Applied to a 15,844 m² non-fruit tree park in Kermanshah, Iran, the model was tested across five scenarios with/without treatment/storage systems. Results show 85% groundwater reliance in unrestricted access (Scenario 1), risking depletion and subsidence, but alternatives reduce this by >80% in constrained cases (e.g., 56% greywater and 23% wastewater in Scenario 2; 60% wastewater in Scenario 3). Final storage of 29 m³ ensures reliability, with operating costs lowest for groundwater but viable for alternatives (e.g., 70% greywater in Scenario 2). This tool aids planners in sustainable urban greening amid scarcity, aligning with SDGs 6 and 11.
