Water reuse can reduce the amount of freshwater diverted from sensitive ecosystems, as well as the amount of wastewater â and the pollution it carries â discharged to waterways.

Because of nutrients retained in water when it is not treated to drinking water standards, irrigating with recycled water can reduce chemical fertilizer use.
