consider the role that wastewater recycling plays in the optimal extraction of groundwater, a renewable resource. We develop a … two-sector dynamic optimization model to solve for the optimal trajectories of groundwater extraction and water recycling … for agricultural users, while desalination supplements household groundwater in the steady state. In both cases, recycling …
