Rainwater Harvesting for Urban Landscape Irrigation Using a Soil Water Depletion Algorithm Conditional on Daily Precipitation

The supply of various non-potable water usages based on the harvesting and management rainwater in urban areas allows to save high-quality resources for strictly potable use limit squandering precious freshwater resources. A system included a reconversion project former military area located town Genova (Italy) is examined. Rainwater collected used landscape irrigation public areas. Three collection scenarios are considered while varying size storage tank, using daily rainfall data from local long-term record as reference climatology. behavioural model adopted simulate operation improved with dedicated algorithm account actual soil availability vegetation its temporal decay, specific type vegetation. For each scenario/tank combination, reliability indices calculated compared, detention time annual usage volume per unit tank capacity indicators quality deterioration economic benefit associated exploitation resource. best solution terms scenario identified.
