Los Angeles Announces Plans To Recycle Wastewater For Drinking

"Faced with a persistent drought and the threat of tighter water supplies, Los Angeles plans to begin using heavily cleansed sewage to increase drinking water supplies, joining a growing number of cities considering similar measures.

Mayor Antonio R. Villaraigosa, who opposed such a plan a decade ago over safety concerns, announced the proposal on Thursday as part of a package of initiatives to put the city, the nation’s second largest, on a stricter water budget. The other plans include increasing fines for watering lawns during restricted times, tapping into and cleaning more groundwater, and encouraging businesses and residents to use more efficient sprinklers and plumbing fixtures.

The move comes as California braces for the possibility of the most severe water shortages in decades.

Snowfall in the Sierra Nevada, which supplies about a third of Los Angeles’s water, is short of expectations. At the same time, the Western drought has lowered supplies in reservoirs, while legal rulings to protect endangered species will curtail water deliveries from Northern California."

"Many cities and towns across the country, including Los Angeles, already recycle wastewater for industrial uses and landscaping.

But the idea of using recycled wastewater, after intense filtering and chemical treatment, to replenish aquifers and reservoirs has gotten more notice lately because of technological advances that, industry leaders say, can make the water purer than tap water. San Diego and South Florida are also considering or planning to test the idea, and Orange County, Calif., opened a $481 million plant in January, without much community resistance, that is believed to be the world’s largest such facility."
