CA homeowners looking to use greywater to save their lawns

Californians looking to keep watering their lawns and plants may be turning to recycled greywater:

At the California Water Resources Board’s recycled water unit, chief Randy Barnard is fielding many calls from homeowners desperate to save their beloved lawns and gardens. “If they’ve got a prize fruit tree they’ve been babying for years, they don’t want to lose that tree,” he said.

But for many, he has some bad news to share. Recycling water at home is not as easy as just hooking your shower up to the lawn sprinklers, and recycled water probably won’t save the lawn…

In California, homeowners are now allowed to irrigate with untreated water straight from bathroom sinks, washing machines and bathtubs, as long as — among other requirements — the water lines run beneath soil or mulch, so as not to come in contact with people. That rules out using untreated gray water on lawns, which typically need above-ground spray heads or sprinklers.

Gray water can even go to vegetable gardens like Negrin’s and Friedman’s, as long as it doesn’t touch root vegetables or any other plant part that’s eaten. Tomatoes are fine, but forget about carrots.

The latest plumbing-code changes have enabled families to install these straightforward laundry-to-landscape systems without a permit, sending wash water into the yard with a valve to divert it back into the sewage system when needed. A handy homeowner can do it with no more than a couple hundred of dollars of piping and parts.

Necessity – a drought though perhaps the state’s required water consumption cuts provide the motivation now – leading to innovation. Three additional thoughts:

1. This hints at the lengths people will go to continue watering their lawn and plants. Not everyone want to paint their lawn or replace it with other surfaces besides grass.

2. Doesn’t this pose something interesting safety issues? What if the homeowners do this wrong and contaminate certain things they grow. Who regulates all of this? I can imagine someone complaining about the children who could be affected by this.

3. If this is relatively easy to do, why isn’t this a common feature of homes already? Even if your location isn’t experiencing a major drought, this seems like basic conservation.

Will outlining the monetary and environmental costs of lawns change behavior?

Americans may like their green lawns around their single-family homes but they come at a cost:

These days, front lawns cost Americans $40 billion a year to maintain, and are spread over about 50,000 square miles—the land area equivalent of the entire state of Alabama.

This vast swath of ornamentally maintained land is generally bad for the environment. A lawnmower generates more greenhouse gas emissions per hour than 11 cars, according to the Environmental Protection Agency; nitrous oxide emitted by fertilizer has 300 times the warming potential of carbon dioxide, and lingers in the atmosphere for as long as 120 years. Swept into waterways, those fertilizers strip the water of oxygen, causing algal blooms and “dead zones” that kill freshwater and marine life.

Then, of course, there’s water use. Americans consume around 9 billion gallons of water a day on average on outdoor use—most of it watering their lawns. That’s more water than families use for showering and laundry combined. As populations rise, water needs will only get more taxing in many states.

The writer concludes by suggesting that California’s drought and trend-setting may just help limit lawns in the future. However, there are at least two major hurdles to overcome:

1. The cultural importance of a lawn should not be undervalued. The minor connection to nature (or “nature” modified appropriately by humans) is important.

2. Simply citing large numbers or figures like above may not go very far. In the abstract, $40 billion sounds like a lot until you consider what kind of money is spent on other things. Or, what might people do instead with that $40 billion? Even the environmental concerns – and the effects sound quite harmful – are more abstract since the consequences are pushed down the road either in time or place.

Perhaps the best way to combat the American lawn would be to change the American view of nature and what is appropriate around single-family homes. We have seen some of the shaming efforts in California, from overhead photos of celebrity compounds to neighbors reporting each other over water violations. This could be done more positively with incentives (such as being paid to remove turf in Western state) or new trends. What suburban resident would want to be the only one on the block with the green costly lawn if all the neighbors had moved on?

More painted lawns in California

Why tear out your drought-stricken lawn in California when you can just have it painted green?

Wasting no time, a Lawnlift employee gets to work in Pearson’s yard by mixing up a potion of water and natural pigments which bring to mind cosmetics used by women every day.

Within minutes, the dessicated lawn is rejuvenated before its owner’s astonished eyes.

“I love it! This is the color of my grass when I water it every day. I absolutely love it. I am thrilled,” she said.

The product is non-toxic, lasts for 12 weeks and is water-resistant — even if the lack of rain is the main threat to California’s gardens.

Power acknowledges that his company is cashing in on the drought, in particular over the last 12 months.

“Sales from last March to this March have easily doubled and in fact we are 150 percent higher than last year and we attribute most of that to the drought,” he said.

California is not the only market for his products: he also sells in Canada, and a few weeks ago made a $15,000 sale to Algeria.

No need to give up that symbol of the American Dream – the manicured lawn – when you can take advantage of ingenuity – non-toxic paint that lasts 12 weeks! I’ve seen numerous articles on this in recent years and I would love to see some pictures of what lawns look like after 12 weeks rather than view more images of the initial verdant pictures from the initial spraying. Perhaps now is a good time to get into the lawn painting industry…

What you can make from giving up your lawn in the West

There are some growing incentives in California and other Western states to replace your lawn with something else:

Even before Brown’s order, some of California’s 411 water districts offered rebates — now as much as $3.75 per square foot — to persuade homeowners to give up on grass.

The Southern Nevada Water Authority pays $1.50 per square foot of lawn replaced with desert landscaping, up to 5,000 square feet. After that, it’s $1 per square foot. Arizona and Utah also have lawn rebate programs…

In addition to paying rebates, the Southern Nevada Water Authority sponsors landscaping contests and offers homeowners free, downloadable designs, divvied into categories, such as “pool-friendly” and “child-friendly.”…

Las Vegas officials say they have removed nearly 4,000 acres of grass, with plans to rip up 3,000 more. In Los Angeles, officials want to take out 25 million square feet of grass by year’s end.

But there’s push-back from the $25-billion-a-year grass industry, which says lawns are good for the environment, producing oxygen, preventing soil erosion and dissipating heat.

Lawns are part of the American Dream and go along with owning a home and having private space. That grass industry is big and many Americans seem to like the status of having a well-kept lawn. Yet, when this dream comes up against ecological realities – as the article goes on to note, LA gets 15 inches of rain on average a year versus 50 inches in New York City – the lawn may just have to go. This isn’t something new; see this earlier post about painting the lawn.

I like the idea of landscaping contests because that would allow homeowners to still fight for status but in more sustainable ways. Perhaps some businesses would even want to sponsor these or offer discounts to those competing. At the same time, I do wonder how neighbors might view some of these new yards, particularly if they are front yard vegetable gardens (one illustration in the article).
