In An Arid U.S. West, Water Agencies Look to Deliver Purified Wastewater Directly to Customers’ Faucets, Despite “Yuck Factor”
ENSIA, August 8, 2021: For decades, water officials in San Diego, realizing the city was facing an ever-drier future, have worked to make the idea of what’s known as “direct potable reuse,” or DPR, more palatable to residents. In the 1990s, that turned into an uphill battle. The technology delivers purified wastewater to customers’ faucets without an environmental buffer — such as a groundwater aquifer, river or other go-between — prior to distribution, so opponents labeled it “toilet-to-tap.” The epithet stuck and torpedoed the Southern California city’s water recycling plans.
