L.A. will make water a terrible thing to waste

The city learned from its earlier "aborted attempt" at water recycling, Nahai said.

"This is a new day," he said. "We have new technology. We're going to reach out very aggressively to the public and engage them as to the facts."

One critic said voters should decide whether the water supply will be blended with treated wastewater. "It's grossly unfair for the mayor, the City Council or the DWP to decide consumers are going to be using this recycled water," said Gerald A. Silver, president of Homeowners of Encino.

But Millie Hamilton, an Encino Neighborhood Council member and docent at the city's Tillman Water Reclamation Plant, said recycling is safe, needed and nothing new. "There is no new water on this planet," said Hamilton, who was referred to The Times by the mayor's office. "We are drinking the same water the dinosaurs drank. All our water has been and is being recycled."

The ambitious water plan carries political risks for the mayor but also could burnish his record as an environmental leader in a bid for higher office. A number of key details remain to be worked out and vetted by the City Council, including the cost of various elements and how they would be financed.

On the heels of a recent DWP water rate hike, Nahai said no additional increases are anticipated. Most parts of the program can be funded from state water grants, the DWP's existing budget and going after polluters who have fouled city groundwater in the past. But future fee increases may be needed, he acknowledged.

David Coffin, a Westchester Neighborhood Council member who tracks water issues, said the plan misses a larger point: controlling growth.

"I don't think they're going to make any headway. They're adding 14,000 to 16,000 housing units a year in the face of water shortages. How are they going to supply all those people?"

Administration officials say the point is to act now so the city can meet increased demand through a combination of conservation and recycling. They note that Los Angeles is an arid metropolis that has grown, in effect, by dipping long straws in far-flung water supplies.

But recent court rulings, environmental agreements and competition from other urban centers are cutting flows or sharply increasing costs of water from the Owens Valley, the Sacramento-San Joaquin River Delta and the Colorado River.

"It's a very sober, prudent and farsighted view," Nahai said of the plan. The administration plan looks beyond "the next couple of years or the next electoral horizon," he said. "We need to start now if we're going to provide for water [use] over the next two to three decades."
