California Gets Past the Yuck Factor With "Toilet To Tap" Water Recycling

HughPickens.com writes: From a marketing point of view, using treated sewage to create drinking water is a proposition that has proved difficult to sell to customers. Now John Schwartz writes in the NYT that as California scrambles for ways to cope with its crippling drought and the mandatory water restrictions imposed last month by Gov. Jerry Brown, enticing people to drink recycled water is requiring California residents to get past what experts call the "yuck" factor. Efforts in the 1990s to develop water reuse in San Diego and Los Angeles were beaten back by activists who denounced what they called, devastatingly, "toilet to tap." Orange County swung people to the idea of drinking recycled water with a special purification plant which has been operating since 2008 avoiding a backlash with a massive public relations campaign that involved more than 2,000 community presentations. The county does not run its purified water directly into drinking water treatment plants; instead, it sends the water underground to replenish the area's aquifers and to be diluted by the natural water supply. This environmental buffer seems to provide an emotional buffer for consumers as well.

In 2000, Los Angeles actually completed a sewage reclamation plant capable of providing water to 120,000 homes — the Donald C. Tillman Water Reclamation Plant in Van Nuys.The plan was abandoned after public outrage. Angelenos, it seemed, were too good to drink perfectly safe recycled water — dismissed as "toilet to tap." But Los Angeles is ready to try again, with plans to provide a quarter of the city's needs by 2024 with recycled water and captured storm water routed through aquifers. "The difference between this and 2000 is everyone wants this to happen," says Marty Adams. The inevitable squeamishness over drinking water that was once waste ignores a fundamental fact, says George Tchobanoglous: "When it comes down to it, water is water. Everyone who lives downstream on a river is drinking recycled water."

    In the Midwest it's common for a city or town to draw from the nearby major rivers like the Mississippi, Missouri, Illinois, Des Moines, and Ohio then treat that water for the tap. Then they take the sewage, separate out the solids, treat the liquids, and release that downstream.

    I'm not sure I'd bitch so much about drinking what my own city or county was purifying on both ends. In the Midwest people are drinking what's been treated for drinking by their city, town, county, or water district but which was treated as wastewater by whoever was upstream. In the spring, sometimes the sewage treatment plants upstream flood. (A few cities and towns even continue to get fines from the EPA for their stormwater and sewage drains combined, so that flash flooding brings sewage up into their own streets.)

    It's worked for decades elsewhere to re-treat wastewater as drinking water. California's supposed to be the progressive leader on this sort of thing. It's time they caught up.

  3. Are they filtering out the pharmaceuticals? by hawguy · · Score: 5, Informative

    For years there have been reports of trace amounts of drugs in treated wastewater that could be harming wildlife and "no one seems to know which compounds need to be removed or how to remove them from the water safely", so are they filtering out these drugs before reusing the water for drinking water?

    Aga said even without knowing exact impacts, consistently seeing antibiotics show up in effluent is concerning.

    “Even at low levels you don’t want to have people ingest antibiotics regularly because it will promote resistance,” she said.

    It looked at samples from 50 large-size wastewater treatment plants nationwide and tested for 56 drugs including oxycodone, high-blood pressure medications, and over-the-counter drugs like Tylenol and ibuprofen. More than half the samples tested positive for at least 25 of the drugs monitored, the study said. High blood pressure medications appeared in the highest concentrations and most frequently.

    Good leaders get kick out of office.
    Why?
    They try to force change, people don't like change.
    They will bend the rules to get their way, this can cross the line into corruption.
    They will step on their opponents, this will toughen the resolve of their opponents so they will be stronger next time around.
    The realize the popular opinion, is based on assumptions made by a population with partial insight into the issue, and that 50% of the population has below average intelligence to really fully understand it.

    Bad leaders stay in.
    Why?
    They are the nice guy you want to have a beer with.
    They try to keep things as they are.
    They flow with public opinion.
    They try to make you feel good about yourself.

    The one nasty trick, even with residential effluent; but especially if commercial/industrial gets mixed in thanks to antiquated, defective, or illicit sewer piping; is that sewage is only mostly dangerous because of the bacteria.

    Drugs of various sorts show up in residential sewage all the time, and have widely varying resistance to breakdown by low cost measures(if you throw enough resources at a chemist just about anything can be separated out, right down to isotopes; but if you can't biodegrade it, destroy it with UV exposure of modest intensity and duration, settle it out with flocculants, or similar cheap bulk methods, the cost will be high enough to be dubiously relevant to water treatment even in the first world); heavy metals show up from time to time and don't do much degrading at all, nasty persistent organic compounds are always a possibility. People just dump all kinds of ghastly stuff down the drain.

    There is a certain...history... associated with people trying to dispose of the byproducts of sewage treatment, where most of these goodies end up, by means cheaper than landfilling. The current strategy involves re-branding them as 'biosolids', composting them long enough that the bacterial pathogens are (mostly) weeded out, and then trying to find suckers willing to use them as fertilizer.

    It's too bad, really. If it were just shit, moderately competent composting practices would turn it quite readily into a safe, useful, soil additive. Dealing with the modest; but very much nonzero, levels of heavy metals and persistent organic compounds has proven to be really hairy.

    I would only drink rainwater, but in norcal it's illegal to capture the rain that falls on your property due to water rights regulations that go back 150 years. essentially, the rainwater that falls on your property doesn't belong to you. in socal I can't capture rain cuz it doesn't rain.

    In some places in the US, this is the case with water rights, but not in any place I know of in the Bay Area. Berkeley and Oakland actively support the installation of rainwater recapture systems.

    ok, take it down a notch maybe. doing more research, it was illegal a couple years ago when I lived in SF, but they changed the law in 2012.

    http://www.jdsupra.com/legalne...

    "Prior to enactment of the Act, the [State Water Control Resources Board] required all would-be appropriators to apply for and obtain a permit to appropriate water from any source, including water falling in the form of precipitation. Under the Act, however, the use of rainwater - defined as "precipitation on any public or private parcel that has not entered an offsite storm drain system or channel, a flood channel, or any other stream channel, and has not been previously been put to beneficial use" - is not subject to the California Water Code's SWRCB permit requirement [California Water Code 1200 et seq.] Relief from the permit requirement enables residents, private businesses, and public agencies to create new on-site water supplies to meet landscaping needs, thus decreasing the use of potable water to meet those needs."
