With growing global focus on sustainable resource use and resilient systems, this work investigates the environmental life cycle impact of adopting agriculture water reuse systems at small communities. Case study data and spatial-temporal modeling quantified resource tradeoffs over time. Excavation reductions and offset fertilizer compensated emissions from electricity use and water reuse infrastructure. Increases in crop yields provided the largest environmental benefit for adoption of the water reuse system at previously rainfed sites. Water reuse system benefits are highly dependent on supply-storage-demand dynamics. Relative sizing of agricultural land to lagoons was the most significant factor influencing water application rates among sites. Seasonal precipitation variations was the key driver of water reuse application within sites due to coinciding effects on lagoon supply and cropland demand. Benefits are sensitive to changes air emissions occurring on the agriculture land and further emphasizes the importance of proper fertilizer management when adopting water reuse systems.
