All Things Water

In my Permaculture Design course, the mantra that has been drilled into my head is:

WATER
ACCESS
STRUCTURES

Water is the VERY first thing we should be designing around ALWAYS, without exception. Water is a broad topic within the PDC curriculum and for very good reason.  Without water, life is simply not possible.

As with most Permaculture topics, by no means do I feel remotely confident yet in my abilities to harvest and manage water in all situations, but I certainly have had my eyes opened to a lot of different techniques.   By far however, the most efficient, inexpensive way to harvest and store water for use by plants and trees is by way of the soil.


The soil?   What?????   What about rain barrels, storage tanks, swales, ponds, dams and trenches?   Well, yes, those have a place (and very specific applications), but so very often, the simplest, most efficient, cost effective method to harvest and store water it is to improve your soil so that it can absorb and retain water all by itself.  Ahhhh... the simplicity of that is revolutionary! 


Feeding and nurturing your soil by adding lots of varied organic matter can improve the soil structure quickly, creating a spongey texture that will absorb and hold water.  When combined with planting fast carbon pathways (plants to chop and drop or cover crops to work in), the soil will make dramatic improvements in its ability to store water (not to mention boosting fertility exponentially at the same time).  Quite literally, THOUSANDS of litres of water can be stored in your soil without any collection or storage equipment, and if you have taken care to properly mulch your soil (to prevent evaporation), that captured water will be held in situ and released gradually to the plants as water is needed with absolutely NO involvement on your part.  In some circumstances (and in some climates), soil building alone won't be enough to meet water requirements.   However, improving your soil can go a surprisingly long way in dramatically reducing the amount of water required to collect, store and irrigate with.

I am slowly learning that by looking to the natural world, we can learn volumes about designing efficient systems.  A truly brilliant permaculture design literally designs the labour (and the working parts) right out the system.   Sustainable, intelligent design is patterned after nature and will function without your input (or at least with very little input on your behalf).  I've got a LONG way to go in my learning, but this revelation is a certainly the firm foundation of good design...

  1. We've been mulching with wood chips, and when I dug some trenches for potato planting recently, I was amazed at how moist and loose the (formerly clay and dry) soil was underneath. I really think you're right about studying how natural systems work, and trying to mimic those in our own efforts!

    1. Wow - Jaime, planting potatoes in your third trimester? I've TRIED to do that, but it was NOT easy with a baby in the way, LOL...

  2. This is a good reminder that simple solutions are the best. I love a permaculture post, so I shared this on my facebook page.

    1. Hi Liz :) Thanks for sharing my post. Simple REALLY is best, isn't it?

  3. Interesting and very applicable here, so the access and structure part?

    1. Rose, "access" relates to accessing elements in your design and structures relates to hardscape (buildings, etc). We are taught to design around water first, then to consider access next, then finally, structures.

  4. Sounds like a great idea, increasing the water potential at the place where you use it most :)!
