This video with a virtual tour of a water resource recovery facility — commonly called a wastewater treatment plant — discusses how these facilities recycle the water and waste we flush down the drain. Water resource recovery facilities can also recover nutrients, generate energy, and create biosolids for use as fertilizer. This tour takes viewers through primary, secondary, and advanced treatment as well as the plant headworks and biosolids treatment process. It is developed by the Water Environment Federation and Gage 3D Studios (www.gage3d.com).
