Rainwater Harvest
Captured rainwater can be used to dramatically reduce a building’s potable water use. Most commonly it is utilized for irrigation but in these examples, the harvested rainwater is used for toilet flushing too, eliminating the use of potable water for sewage conveyance. Cisterns for storage can either be visible green design features such as the rooftop cistern at the Southface Eco Office or the exposed, agricultural-style above ground cistern at the Grand Bay NERR Visitors Center, or hidden below ground like the supplemental in-ground cistern at the Eco Office.
