Highlights from the Biodynamic Compost Workshop

 

On Sunday, August 17, 2008 we had a fantastic Biodynamic Compost workshop led by Jack McAndrew.  Biodynamic compost is the premeir compost, rich in the life forces that make soil come alive.  It was a simple process.  Traditionally, it would be a mix of 1 ton cow manure (1 pickup truck load), some alfalfa hay (alfalfa roots reach down almost 40ft into the ground, mining precious minerals vital to the compost pile and your garden), kitchen scraps, some fresh compost to act as a starter, as well as a biodynamic prep that you can buy from the Josephine Porter institute in Virginia (http://www.jpibiodynamics.org/).  When we made the compost we used horse manure and available organic matter that we can find.  It all works in the long run, but the premeir compost is made with the materials described.

 

I forget the exact dimensions but ideally you want it somewhere near 3 ft wide, 10ft long, 3-5 ft high.  The layering process started off with some rough material (coarser leaves, small twigs), some water, manure, sprinkle of biodynamic prep, alflafa, water, manure, water, straw, water, compost, biodynamic prep, alfalfa, water, etc.  Each layer is about 2" thick, spread evenly.  As you can tell there is a lot of water involved.  The pile needs to be like a wet sponge and in our climate, that is where most people go wrong.  So make sure that pile is watered.

 

I am sure I missed a lot, I have added some handouts that were available at the workshop for those of you who did not get any.  They are located in the File Library section below on the left hand side.  PLEASE ADD TO ANYTHING I MAY HAVE MISSED.  THANK YOU.

I'm in, I have this garden going off the hook right now and can't hardly give enough away.  Soon I'll have a lot of saved seeds as well.  Let me know when it gets going.  Thanks for starting this up.

I am creating a few links for you to go to if you would like to learn a little more about the principles of permaculture.  These resources can help clarify and expand upon what we covered on Monday, June23,2008.  There's more so please, add your own.

I am sure you are looking into moisture condensers for the purpose of drinking water, but I had an observation yesterday morning that fits along with this topic. 

 

I live close to the coast in Malibu.  We often get marine influenced weather where I live.  In this one spot we have planted a few coast redwoods that are over 10 years old now.  The morning saw a typical low level marine layer that held a lot of moisture.  The redwoods were acting as a condenser and caused droplets of water to fall from its leaves.  The air all around the redwoods felt more moist than other spots in the yard.  This led me to think, with the right plantings, maybe we can create more moist microclimates that harvest the mist naturally and minimize the need for irrigation.  It would be great to see more plantings established that take advantage of this scenario.

 

I hope this helps in another sense.

City of SM encourages Rainwater harvesting -- may not support you directly but they encourage you.

I went on the Green Gardens tour in April, and one of the properties, at 814-818 2nd Street has created a completely awesome and up to code rainwater harvesting and irrigation system for the building (20 units of apartments). The garden designers are: www.flowertothepeople.com and they created (I am quoting, not creating this language):

"an underground 840 cubic foot private aquifer (a cistern storing captured stormwater) that has an approximate holding capacity of 5,600 gallons. During the winter rains water on the roof is channeled into gutters and then into a drainage system that directs the stormwater into either the aquifer in the front yard, the pervious area of the center courtyard, or a small pervious area in the back walk to the alley.

"The underground cistern is comprised of water-holding EcoRain (tm) plastic cells encased in an impervious polypropylene line (pond liner). With the addition of a water level sensor, pump, and control valve, the cistern water can be reclaimed for use in landscape drip irrigation. The existing concrete driveway and concrete center of the courtyard were removed and replaced with a plastic structure grass paving, making the entire 860 sq. ft area a permeable surface capable of accpeting some stormwater runoff, but still tough enough to act as a temporary parking spot. The concrete was reccled as edging for the front yard planted mounds.

"Berms surrounding the front yard create a slight bowl in the middle of each side of the driveway over the new aquifer. This depressed middle area is planted with various riparian ground covers and shrubs, creating a bioswale through which irrigation water and storm water can run, be cleaned up and ultimately be returned to the aquifer, creating a closed system. Variegated, climate-appropriate plants are used to light up the front gardn despite the shade create by the median ficus trees."

They were aiming for zero runoff. They also got a City of SM Landscaping grant. Before the renovation they were using about 57,000 gallons of water per year. They doubled the planting area and cut the annual irrigation in half.

I have a complete information sheet on the project, with plants used, and description of their cistern and recapture structure if anyone is interested -- I have one hard copy, not an Internet version, so trees may have to be sacrificed if I make copies....

if the focus is on demonstrating a system, code-compliant or not, it seems that if this is NOT an illegal activity, it would be great to see what the folks from the Bay Area can show us all in July.

if there is a parallel goal to update the codes allowing for lower-cost and/or alternatively-designed systems, perhaps folks would be more supportive AFTER they've been involved with a demo.

however, i  personally am not in favor of breaking the law or generating furor and controversy as the first step in building community support for greywater code revisions. I'm all for citizen activism, but this issue doesn't seem to warrant civil disobedience.  if geofrey is correct, now may be the time to work within the system rather than attempting to by-pass it.

perhaps in addition to consulting with a group like rewater.com,  we might look to the city of Santa Monica for support on the issue.  the city has conducted research into the costs, safety and conservational aspects of greywater usage and i'm sure someone from the Sustainable City program (at Dean Kubani's office) would be available to help in some way.

I was looking to do a lo-cost do-it-yourself greywater demo in Topanga a few years ago.  I was ultimately dissuaded  from pursuing this, despite some local enthusiasm, for I am an employee of the Resource Conservation District of the Santa Monica Mountains; for us to sponsor an "illegal" installation was problematic despite its potential value in stream water quality improvements, water conservation and re-use etc.  The irony is that we (RCD) would love people to install these greywater systems, especially when it involves conversion of daylit "pipe to creek" greywater drains, amazingly still quite common (and illegal) up there.  We are a non-regulatory agency, and favor solutions over punishment.  I (unofficially) say "Go for it!"   ----S

It’s important to establish new rules for laws that are decades old now.  Darren’s suggestion here is a good one:

I would consider it a legitimate option, for example, to intentionally publicize the workshop, expect hassle and possibly legal action from whatever health department or dept of building and safety has jurisdiction, and use any such attention and controversy to attract media attention and publicize the stupidity of California greywater laws as part of an effort to effect change.

However, as an architect that spends too much time getting permits for building, I believe now is a great opportunity to rewrite the code.  With schwarzenegger’s announcement of the drought, and Villaraigosa’s ‘green’ tendencies, we could work to show a way for Angelenos to more simply install grey water use.  In fact we’ll have to as an unsustainable city.

For example, Mike Reynolds whom I worked with, has perfected systems that have lasted decades.  (www.earthship.org)  Wouldn’t it be awesome if with the help of the guerrillas, we could raise the issue and prove a new system that is codeworthy and make it viable (read; sustainable) for these systems to go into affect citywide.

PS

Here’s a website that promises a to code grey water system for less than $5000.  www.Rewater.com
Perhaps they could consult with all this.

Hi All,
 
It should be noted that it's illegal in California to install greywater systems that aren't permitted, and that California law requires holding tank(s) and pump(s) that make installation expensive and systems unwieldy to operate and maintain. I know of only one permitted system in Southern California, and it took at least a couple of years and about $50,000 to install. There are estimated to be at least hundreds of illegal systems operating in Southern California.
 
For any host of such a workshop installation, the decision should be made in advance to either comply with the law or intentionally break it. I would consider it a legitimate option, for example, to intentionally publicize the workshop, expect hassle and possibly legal action from whatever health department or dept of building and safety has jurisdiction, and use any such attention and controversy to attract media attention and publicize the stupidity of California greywater laws as part of an effort to effect change. For at least two years I've been discreetly looking for a client who would be interested in working with me to create some furor over greywater or composting human waste. At minimum, anyone who hosts such greywater workshop installation should understand that unless such an installation complies with California law (and my understanding is that all gravity-fed, intelligently designed greywater systems are currently ill egal), that there could be legal action, fines, an order to remove the system, etc. Again at miniumum, until laws change, any homeowner should expect to remove an unpermitted greywater system to bring the house back up to code to pass inspection prior to being able to sell it, or to do so within 30 days at any time based upon a legal order.
 
There's nothing illegal about doing a demo, so a workable compromise might be to set up a washer with a piece of wall or plywood as a stand-in in a yard or at a community garden to demo a setup. This wouldn't be as fun as doing a permanent house install, and connecting to water and power to get the demo functioning might be difficult, but it would have the distinct added feature of being legal.
 
Projecto Jardin, a community garden in East LA, was interested last summer in my doing a greywater installation demo from a sink onsite to plants as a workshop and we never worked out the details. They might still be interested. I'm connected to many groups and hundreds of people throughout Southern CA who are interested in sustainability and related issues, and might be able to find a location if no one from the immediate mailing volunteers. I would consider it important to define in advance what the position will be on legality and whether or not the installation would be seen as a possible opportunity to challenge idiotic laws and possibly attract controversy and media attention.
