WATER RECYCLING:
Guest Column: Revisiting 'toilet to tap'; This time around,

Given this scary situation, the DWP earlier this month asked a handful of private contractors how to promote "recycled water planning" and, in the words of DWP representative Carol Tucker, "to explore all options with our stakeholders for recycling water." Tucker insisted that turning sewage into tap water was not part of the plan, and other DWP officials have echoed her message.
But the water agency's request for ideas about recycling was explicit. It spoke of "indirect potable reuse," which means restocking groundwater with purified wastewater.
Sound vaguely familiar?
It should.
The new study might cost $1.5 million, but most of the needed equipment already exists. It's called the East Valley Water Reclamation Project.
Built in the 1990s at a cost of $55 million, it was used for a few days then shut down seven years ago. As DWP engineer Bill Van Wagoner put it, "We spent slightly under $1 million per acre foot (of water produced) before we had to shut it off." That comes down to about $2.75 a gallon -- as opposed to the fraction of a cent per gallon usually paid by DWP customers.
The problem? "Indirect potable reuse" got a bad new name: "toilet to tap."
Public hearings on the reclamation project's safety were held in 1995. The Los Angeles City Council then greenlighted it unanimously after the Los Angeles Regional Water Quality Control Board, the state Department of Health Services and the state Environmental Protection Agency also approved the proposal.
It worked this way: Sewage was treated at the Donald C. Tillman Water Reclamation Plant in Van Nuys and then pumped to spreading fields near Hansen Dam, where, over five years, it would filter through sandy soil and gravel into an underground reservoir.
But what should have been an engineering triumph soon became a PR disaster.
For five years after its approval, the reclamation project was largely forgotten. Then came the official DWP announcement of its completion in 2000, just before an open mayoral contest in 2001 that included Valley secession on the ballot. The water agency could not have chosen a more inopportune moment.
The new pipeline, providing enough treated water for 120,000
Mayoral candidate and Valley council member Joel Wachs, who also had approved the plan in 1995, cried foul in 2000: "Go tell somebody in North Hollywood that they have to drink toilet water but the mayor [Richard Riordan] won't have to drink it in [his]
Wachs was utterly wrong.
At the time, the DWP insisted that the treated water from the Tillman plant was almost potable, and when it reached the water agency's Valley wells, it would have a purity indistinguishable from unpolluted rainwater.
Few listened, however. City Atty. James K. Hahn, planning his own mayoral run, discretely ordered the recycling project shuttered for no other visible reason than the public protest. As mayor, he later reaffirmed his order, and the DWP promptly ran and hid from water recycling.
Back then and now, however, water treated at the city's main Hyperion wastewater plant goes into other cities' water supplies. It flows into aquifers supplying
This is because modern water-purification technology is considered totally reliable. It uses micro-filtration and reverse osmosis, which pumps water through permeable membranes, and ultraviolet light to remove all contaminants. The "yuck factor" is now completely imaginary.
"We started telling people from the start that we're purifying sewage water," said Ron Wildermuth, district communications director, for the Orange County Water District.
The district also mounted a substantial public education campaign that should become a model for the DWP's plan to relaunch its own ill-publicized recycling program. By November,
Every day, the outflow of
In these dry times, it makes perfect sense to stop throwing it away.

Gov. Arnold Schwarzenegger, environmentalists and water districts have waded hip-deep into arguments over new dams, pricey canals and other ways to manage future water wars in
But the looming water crisis that the governor warns of is already here.
Hundreds of small, rural communities throughout
According to the state Department of Public Health, public drinking water systems deliver water with unsafe levels of contaminants to approximately 1 million people. The vast majority of this tainted water flows to the Central Valley - to little-known towns such as Monterey Park Tract, Mendota, Parlier,
In 2004 alone, tens of thousands of
More than 90 percent of
Unfortunately, years of intensive farming with uncontrolled chemical use has heavily poisoned that source. Recent groundwater sampling in
When contaminant levels spike or wells fail, no large water agency stands ready to come fix broken treatment systems. Most of these small communities must shoulder the costs alone, paying for expensive maintenance and operations out of the lean budgets of a couple of hundred farmworker families.
These contamination and infrastructure problems have grown unchecked since development in the
Virtually every water agency ignores
Meanwhile, the state has developed an elaborate and expensive system to pipe crystal-clear Northern California river water to
Without the ability to hire highly paid staffers and lobbyists, farm families find their voices drowned out by the raging debates about
Instead of talking about future water needs, we need to talk about the chronic lack of access to clean drinking water
The state could play a lead role in developing innovative solutions and projects to address the problem. Right now, regulatory and water resource agencies acknowledge the level of contamination but have refused to take action.
Many organizations have developed projects and proposals that would take important steps to relieving the drinking water crisis, such as requiring groundwater management plans of industries and agencies, setting aside state funds to address the contamination and requiring water districts to work with communities that do not have clean drinking water in their area to develop alternative water sources. Unfortunately, most of these programs fall apart as soon as industry objects and then the state shirks its duty, saying the problem is too big, unwieldy or out of its jurisdiction. Time and again, we have seen agencies, legislators, and policymakers fail to take meaningful action on groundwater protection and management, because it is a tough issue.
The governor is right. We do need to invest in
