Part 1 It’s not hard to install a greywater system in your home, but it’s also not hard to do it wrong! In this info session we’ll help you get it right by looking at how systems are designed, installed, and permitted, and how to choose a greywater system that’s right for you. We’ll have all the specialized parts and a sample system on hand. Bring your questions!

Part 2 We’ll build on the info from Part 1 by actually installing a simple washing machine greywater system. Students will learn to safely and competently install the interior hardware adn exterior mulch basins that make up a classic “Laundry2Landscape” system. Students are encouraged to bring questions and info about their own sites, work clothes, gloves, and lunch.

Instructor Malena Marvin is the only Certified Greywater Installer in southern Oregon and runs Elemental Design/Build, a small company using natural patterns and flows to inform design of beautiful and innovative human habitat, indoors and out.

Taking ecological design to new heights!

Alaska Airlines Magazine

We can rarely predict from whence our 15 minutes of fame will arise, and I certainly did not expect Alaska Airlines inflight magazine would be featuring my greywater work.  But I’m glad to get even a few small words out about greywater and ecological design to thousands of captive passengers at 30,000 feet. I am interviewed, albeit briefly, in an article about the design/build philosophy that features many great folks from the Yestermorrow community, including Matt Wolpe of Just Fine Design/Build, whose creativity, productivity, and social engagement totally inspires me.

My part of the article, authored by Joe Follansbee, goes something like this:

While conventional architects or builders may walk a site several times and figure out a way to shape the site to the context, some design-build advocates will study the site’s ecology, including the flow of water in and around the site, and the microclimates created by climate and vegetation.

That’s the attitude of Malena Marvin, an outdoor educator and consultant who also designs gray water systems in Ashland, Oregon. “Gray water” is used water from sinks, showers, and baths that is clean enough for other purposes, primarily irrigation.

Marvin advocates for a detailed analysis of the site, down to the soil type and climate patterns. Ideally, a good structural design has little impact on the environment, and may even enhance local natural processes.

Furthermore, Marvin argues that architects should spend as much time as possible outdoors. “We need people who are ecologically fluent, which has to be learned outside,” she says.


Greywater growing stronger!

Greywater-irrigated asian pear tree in southern Oregon.

MY 3 year old asian pear tree produced its first large crop of fruit the season it was irrigated with laundry greywater.

This morning’s September rains signaled an end to another hot, dry summer in southern Oregon, and the first season of greywater irrigation in my yard. As my household enjoys the abundant plums and pears we grew with laundry water this year, I’m reflecting on the growth of greywater in my life, in my community, and across the nation.

With news of greywater legalization in Colorado, greywater is now somewhere in between gay marriage and marijuana in terms of state-level legality. Of course, one day we’ll look back and wonder why we ever thought it was not only a good idea – but the law – to sully perfectly clean water with our waste, than treat it with chemicals and put it back into our rivers. But for now let’s celebrate the small victories: Colorado joins Oregon, California, Washington, Arizona, Texas, and New Mexico as places where people can reasonably re-use their own greywater without becoming outlaws!


I’m also pleased to report that this summer I graduated to the top ranks of the greywater installers among my certifying organization – Greywater Action. I’m now one of three Greywater Associates nationwide, and the only one doing business outside of California. Being a Greywater Associate means that in addition to my certification I’ve completed and received feedback on a minimum of five systems professionally, that I’m actively collaborating with Greywater Action, and that I’m working to ease permitting barriers and provide education about greywater systems in my local area.

As my experience with integrating greywater into ecological designs and job sites grows, I’m excited to be doing more collaborative education and consulting. In addition to reaching local networks, I’ve enjoyed connecting with folks around the state and the country who want to include greywater in their larger classes and workshops. On the ground here in southern Oregon, I’m seeing such a need for skill building, not just for folks who want to learn and implement DIY progressive water design, but also for all the plumbers and contractors whose clients are asking for greywater. Most tradespeople at this point have little experience with alternative water systems, and also don’t have a lot of extra time and energy to devote to learning a new craft. It’s fulfilling for me to be able to step in and offer the answers clients are looking for, and help interweave this simple, fun solution into peoples homes and lives.

Greywater, of course, is one element of ecological design – a method of creating human habitat in keeping with nature’s principles. I encourage folks to see their own homes and yards not just as habitat for people and wildlife, but also as fertile ground for growing a new relationship between humans and nature. Like the laws that make greywater illegal in most of our country, we’ve inherited a lot of ingrained patterns in our built and legal environments that make it very difficult to live sustainably, equitably, and regeneratively in our communities. The good news is, we’re changing this! Ecological design, permaculture, and the constellation of elements that they encompass are gaining ground everyday. Here’s to a great growing season for greywater – may we continue to water our species’ good seeds by working together to change the world.


Winter Dreams Summer Garden…

Ver2_2013_WDSG_Takeaways (2)

I’ll be bringing the demonstration Laundry to Landscape greywater system to the 2013 Winter Dreams symposium this fall. Put on by the Jackson County Master Gardener’s Association, the symposium is Saturday, November 2nd from 9 to 5 pm at the RCC/SOU Higher Ed Center in downtown Medford.

This is a great chance to learn cool new stuff, with four workshop slots and 10 great workshops to choose from in each slot. I know I’ll be staying after my presentation all day and learning about fermentation, mushroom cultivation, and landscape design from the experts in our valley – what fun!

Don’t dump that water – reuse it…

A great deal of household water can be recycled and piped outside for gardens and landscaping under a state law set up last year, and Ashland aquatic ecologist Malena Marvin, who installs graywater systems, will offer do-it-yourself classes in May.

“It’s easy to do, but it’s also easy to do wrong,” says Marvin, who has started the 100 Houses Graywater Challenge and is trying to get city planners interested in helping and promoting it.

“It’s important we do these right and that, if you do it yourself, that you have a consultant work with you,” she says, “so it will become talked about and accepted as a normal, good idea. We don’t want to have people winging it, then having problems, so then people think graywater is a problem.”

Graywater is household waste water diverted from one of four sources — washing machines, bathtubs or showers, bathroom sinks and kitchen sinks — and reused for irrigation. Water from toilets, dishwashers and garbage disposals can’t be used. Graywater can be used on trees, landscaping plants, compost, lawns and gardens, but not for edible root crops such as carrots and beets.

Until last year, graywater reuse was not legal in Oregon. In 2009, following the lead of several other states, the state Legislature passed a bill directing the Department of Environmental Quality to set standards and create a permit structure for graywater reuse and disposal systems. The agency completed the process in 2011 and began issuing permits last spring.

Costs for the permits vary depending on the type of system being installed. Costs and other details can be seen on DEQ’s website at www.deq.state.or.us/wq/reuse/docs/graywater/PermitsQA.pdf.

Showing the system in her backyard, Marvin, 35, shows how the flow is controlled by a three-way valve inside the house, so waste water can either be sent to plants or to the normal sewage or septic system.

Waste water travels to landscaping through 1-inch high-density polyethylene pipe. In Marvin’s system, the water goes into 4-foot-long “mulch basins” that are filled with bark dust. Roots of nearby plants suck up the precious liquid, she says.

Marvin was trained in graywater design and installation in California. She says she plans to get a contracting license soon.

Marvin does consulting on the systems and notes she can help with the DEQ paperwork and site plans. Permits require homeowners to calculate how much water the plants will use, she says, and that determines how much water you can divert to yards. They also require waste water to be 4feet above the summer water table. The systems are turned off in winter.

Marvin built an outdoor shower with mostly recycled materials and will hook that up with her graywater system.

“It’s about how to blend ecological design with esthetics,” she says. “It’s a great opportunity to interact more meaningfully with our own landscape.”

Marvin will offer a hands-on, DIY “Laundry to Landscape” workshop May 17-19. Participants will learn to modify a washing machine’s drain line, set up irrigation and design their landscape to make the best use of the water.

The workshop costs $135. Register at 541-821-7260 or www.elementaldesignbuild.com.

Help Elemental win a small business contest! Vote here!


In the spirit of leaving no stone unturned, I’ve entered Elemental Design/Build in a vote-online small business contest and could really use your help with the online voting. If I’m selected as one of the 15 winners, my “wish” for $5,000 toward a contractor’s license and new tools would be granted! How cool would that be!

Did you know women-owned businesses make up just 28% of Oregon’s businesses? I don’t think that’s because we’re 28% as smart, or 28% as capable. I think this has a lot to do with access to capital, and many womens’ relative discomfort with demanding their share of the financial pie. I’d really like to make Elemental a shining example of a woman-owned business for other women to be inspired by. And I’d also love to see a green, progressive business highlighted as one of the 15 winners in this contest.

So what are you waiting for! Go vote! And remember you can come back once a day and vote for Elemental to help me win.

50 Shades of Greywater, the article

A short article I just wrote at the request of the Klamath Falls Sustainable Communities group…

Yours truly testing out a system before filling in the basins with mulch.

Yours truly testing out a system before filling in the basins with mulch.

Many of us in the water-starved arid west are letting a valuable resource get away from us: the greywater from our washing machines, sinks, and showers.

How silly is this…
Suburban Americans spend money to fertilize and then irrigate our gardens and landscaping with treated, potable water. We then turn around and sully additional potable water with soaps in our homes (effectively making it into fertilizer) and send it down our drains to the sewer, and eventually our local waterways via the treatment plant. As it turns out, sewage treatment plants are great at killing bacteria, but terrible at reducing the nutrient pollution from household soaps and greywater. In Klamath Falls, the Klamath River is already polluted by agricultural nutrients, and our greywater only adds to this Clean Water Act-violating pollution! On top of all this, up until last year, correcting this maddening situation with a home-scale diversion was 100% illegal! It’s enough to drive a person nuts with lots of exclamation points.

Subsurface greywater irrigation can be pretty simple, using the washing machine's pump to send nutrient-rich water to the plants that need it.

Greywater outlaws no longer!
The good news is, it’s now legal to take matters into your own hands and create a decentralized, systemic solution to our current water problems with residential scale greywater systems. The Oregon Department of Environmental Quality legalized greywater diversions in 2012, and for $90 will issue you a permit to divert all the greywater in your home away from the sewer (and the river) and toward your thirsty fruit trees. The application for the permit itself is not super-technical, but there are some “grey” areas and so getting a little background in greywater is not a bad idea. The permit also requires you have fairly extensive documentation of your system on hand, so unless you’re a very adept DIYer with a background in sustainable water systems, I suggest you get some help.

50 Shades of Greywater
There are truly at least 50 shades of greywater systems out there, but some have proven more effective than others for the greywater pioneers who’ve been testing them for decades in California and Arizona. We owe a lot to Art Ludwig in this regard, the Father of Greywater and author of the classic text “Create an Oasis with Greywater.” My own training comes from Greywater Action, a group that took Art’s progress and ran with it, working to legalize greywater in California and pioneering hundreds of installations. After following up and studying the effectiveness of their “research and development” in homes around California, the folks at Greywater Action sure make great teachers, and I’m proud to be one of their Certified Greywater Installers.

Once installed, however, greywater doesn't have to look like greywater, it just looks like a thriving, beautiful landscape.

From Laundry to Landscape
Home-scale greywater diversions are usually done with the drain water from sinks, showers, and washers. Washing machines are the most popular “low hanging fruit” of greywater, because the diversion can be made without slicing into the house’s plumbing, and because washers have a built-in pump which gives you more options for irrigation. There are a variety of ways to get your washing-machine water out to your yard, the simplest being taking its drain hose out of the wall and sticking it out the window. To avoid ranging into outlaw territory though, you’ve got to pipe that water 6” underground for “subsurface” discharge, and it’s got to be directed at vegetation calculated to use the water as irrigation. In most cases, folks will want to use a Laundry2Landscape system that features an interior 3-way valve (legally required so you can choose whether to direct the flow to the sewer or your yard), and mulch-filled drainage basins sized to accommodate your flow and placed strategically around your perennial landscaping. Your shrubs and bushes, by the way, will thrive with this nutrient-rich, steady source of irrigation at the roots!

Gettin’ er done
The good news is that a Laundry2Landscape system can be installed in a weekend by a trained DIYer, with a cost of around $200 in parts. I do recommend either attending a workshop (informational or hands on) or getting a consultation, as there is a complicated materials list and some fine points that can make or break the system.

Elemental Design/Build and your greywater system
I’m available to help you at whatever level suits your skill level and budget, from a one hour consultation to make sure your ducks are in a row, to a weekend installation class, or a comprensive, water-driven ecological design of your whole property. I’m offering a 3 hour “info-session” (April 13th) and a hands on weekend installation workshop (May 17-19) in Ashland this year, and I’m happy to repeat these workshops in Klamath Falls later in the spring if there is demand for it.

100 Houses Greywater Challenge
I’m leveraging a one hundred house challenge for southern Oregon in 2013, banking on the fact that once a group of trendsetters paves the way, greywater diversions will be a common place feature in every home. If you take the 100 Houses Challenge, you’ll get a cool t-shirt, a sign for your yard if you want one, and recognition on my website if you choose it.

Please don’t hesitate to call or email me with your questions, and with the help of Leslie at KSC, we can organize some visits to Klamath Falls this spring so we can plan a greywater oasis for every yard that wants one!
