A Cost-Benefit Analysis of Rainwater Harvesting
Analyses of local rainfall data and predicted potential water usage at commercial facilities in Arlington County, Virginia reveal that rainwater harvesting systems conserve potable water, protect surface water quality and minimize flood risk. However, economic analyses from the perspective of a private developer using two case studies of commercial developments in Arlington suggest that the benefits of incorporating rainwater harvesting into building designs do not justify the cost of implementing this technique. Notwithstanding, results from a sensitivity analysis indicate that charging tenants a modest price premium of one percent or less for the privilege of occupying a “green” building yields a positive return to investing in rainwater harvesting.
