When you have access to unlimited water, you just don't appreciate water the same way as when you are on tank water, the supply is limited, and you have to bucket greywater to each and every one of your plants that you want to live.
I wheelbarrow a large container of water back and forth, bucketing water from a greywater container onto my plants - much cheaper and also more helpful to my plants than a gym membership. But it is hard work for the value you will much later harvest, and all the lifting can injure my back. Since Auckland is experiencing drought conditions of the like of which I have never seen in my 9 years living here (but apparently in 70 years), the only water my garden has gotten in the past month or wo has been hand carried.
(Basically, instead of hosing directly from our water supply onto the garden, we use water in which we have washed our clothes first - since we have to do laundry anyways.)
I have stopped buying new seedlings, as we have the space in my veggie patch - but not enough water (or time and energy to deliver it).
In a documentary I saw, societies can only thrive if they have water - which is obvious - but in this situation of complete water delivery using my own energy along, I can feel exactly how related water is to life.
If a plant has water - it lives. How much water I can afford, is how much life I can support in my garden.
Water = life
