How much water do we use?

18 years ago

In the last few years many of us have had to deal with drought, often drastic or prolonged, and I think many of you share my suspicion that a shortage of water is a problem that's not going to go away soon. Here in my corner of Italy the last two winters have hardly been winter at all, not chilly, not wet: a far cry from the stories my neighbor (younger than I) tells me of the winter of 1985, when a driver didn't have to worry sliding off the icy, curving hill roads because snow was banked so high on the sides that escape was impossible. I remember myself in 2000 traveling from the Po Plain to Innsbruck in December and finding myself warmer in Innsbruck. Of course weather runs in cycles, and I don't doubt that we'll have sopping, muddy, freezing, miserable winters again; still, the trend appears to be towards warmer and drier weather, and I want to be able to live and to garden with it.

Our property's water needs for both house and garden are met by the local network of treated water. We don't have a well. The local water network is limited; in the summer of 2003, a great drought year in many parts of Europe, it ran dry entirely, and water had to be brought up by truck. I dislike using treated water for the garden anyway; it strikes me as wasteful; but we need some water if we're going to garden at all, for potted plants, rooting cuttings, and plants that have been planted within the last year. We water all these by hand and about as sparingly as we can while keeping them alive.

The garden is becoming more and more a dry garden: I mean, one that doesn't get any water except that for the plants in the first year. We work at water conservation by mulching our plants heavily, and by planting (at least trying to) in the fall, not the spring, to give the plants more time to get established before the summer heat and drought hit. We're aided by our clay, water retentive soil. I render up thanks for every summer thunderstorm, for every unseasonal rainfall. At the moment it's raining, finally and at last, after a dry winter and early spring (roughly four inches in four months); in the last two weeks we've gotten, what? two inches perhaps, and the forecast says more to come. The plants love it. Everything is green, green, green; and the plants, the ground, the aquifers will be marvelously fortified in preparation for the coming of summer.

When it gets dry we become stingy and inventive with water in the house, too. I've profited by hints from forum members: a bucket in the bathroom for bath and shower water to flush the toilet; a basin in the utility sink for laundry water to dump on the plants; another bucket in the kitchen sink and more water for the plants. When it get really hot, I take outdoor showers with a standup shower hooked up to a garden hose: it's a shocking experience, but vivid. Last year I gave up my vegetable garden and dahlias: too needy of water (some dahlia tubers that got left behind volunteered anyway, and made themselves beautiful without irrigation). It goes without saying (doesn't it?) that grass doesn't get any water. It's brown and dead in the summer, but then it comes back. I'm really surprised that this year we actually have something that looks like a lawn: we never worked at it. And of course, forget washing cars.

So how did the garden do last year, with one lifesaving rain in June, no rain in July and weeks of 100F temps, one rain in August, hardly any rain in September: it didn't rain strongly until the end of October, too late for a fall flowering of the Teas. My cuttings in pots got massacred: my husband watered, but it was too hot, too dry, too windy. The garden did reasonably well: most plants, new and established, survived, though they weren't particularly happy about the situation. I had some cane dieback and cankers, and am waiting to see how the disease situation will develop this year; the roses looked beaten up by the end of the season; the fall flowering was an outrage. It was an unsatisfactory year, except that most things lived. Now it's a new year. The garden looks SPLENDID; the roses are healthy and covered in buds. I'm looking forward, I hope we will have, marvelous spring roses. It remains to be seen, but the situation is very promising.

Anyway, how much water did we use? We got our quarterly water bill this month. Estrapolating from a nine month period that included last summer, our annual water consumption was 297 cubic meters, or 81,675 gallons. According to the water utility's statistics this is 8.4% over the average consumption for a family of three in the Province of Piacenza. Our garden last year had about three hundred roses, as well as box, yew, clematis, lilies, four o'clocks, bay laurel, privet, lavender, lilacs, palms, and so on.

This is my account of my experience with water, how we use it, what happens as a result, how much we consume. As always, I'd like to hear what you think.

    Here's web site that'll scare you! I thought 81,000 gallons sounded like alot, but evidentally, it's very conservative according to American usuage.according to them..each american used 159 gallons a day..so for 270 days, (your 9 month cycle)..it would be 42,930 per american..then times 3..for your 3 person household... 128,790....yikes!

    i still think that 159 gallons per day per person is way over what a person would use..even with watering a garden..i am shocked.donna

    Our water consumption is below average for our county and way below what is used in our still rural area where oranges and avocados are raised and people tend to have quite a bit of acreage. However, I think part of it is also that we've taken out all the lawn that was here and mulch our plants heavily. I hand water so that the water is directed at the plants that need it the most. Like you, Melissa, we don't wash our cars. I try very hard not to be wasteful with water in the house also. It's actually much more satisfying than squandering a resource that is so precious; unfortunately there are still too many people who don't think this is a concern.

    A lawn uses 4 to 5 times the water of garden plants. There's the math that settles the whole thing for me. Fortunately, grass is perfectly happy being watered with the worst water you can find. Which is what it gets here, untreated, out of the ground. Still, it has to be pumped. It's terribly wasteful in our part of the world. I do like a tiny snake of grass near a hot entrance. It cools the air by several degrees.

    To me this is one of the great mysteries of civilization. Here grass is one of the most drought tolerant things you can grow. It takes considerably less water than garden plants. It's only the people who don't understand plants, or grass, or much of anything else that water their lawns.

    Does that 159 gallons per person include the water to grow our food (in another part of the country), the water to irrigate landscaping at businesses we never go to...and so on. I think it would have to be for all uses, even the ones we don't use. We all share the irrigation of public parks, of golf courses. No bean counter is going to assign water based on individual patterns...at least not yet.

    We have hay fields and we own 100+ acres of forests. The uptake by trees is such that an intermittent stream shown on some decades old maps hasn't been there since the forest regrew.

    I've been reading the New Orleans website and the Mississippi is so high that water is being released through Bonne Carre spillway into Lake Pontchartrain. The two upriver spillways (Old River Control Struture and Morganza) haven't been opened. The volumns of water being released PER SECOND boggle my mine. And the wonderer in me wonders when public works projects on a national scale will be proposed to save the water, or at the very least use it a few times before it gets to the Gulf of Mexico.

    I'm guessing that the Mississippi is high because of all the water we've had in the Midwest. I know the Rock River and I think the Wisconsin River are at flood stage. We're supposed to get more rain tomorrow morning too. We're several inches above normal right now with no sign of it stopping. I wish there was a way for us to ship all this water to places that actually need it. Of course, if it is like last year then we'll have a drought all summer, and another flood in the fall.

    I've installed drip irrigation so I can water my roses more efficiently when the drought does come back.

    My opinion, for whatever it's worth -

    I work in the water industry. My division is called 'water production'. We treat the water, you guys use the water, it goes into the sanitary system and then gets treated then goes to the streams. We have 30 + waste water plants that are upstream from our water reservoir. So everybody flushing toilets upstream - you guys weren't wasting water, you were just sending it to us!

    Water is one of those things that isn't created or destroyed. What we put on the ground for plants is either used by them and released into the air, or evaporated, or trickles back down into the underground reservoirs.

    There are 3 main water issues. 1) We have too many people in some areas where there isn't much water.That limits the amount of water each person can use. 2) In some areas water is being pulled from wells at a higher rate than nature can replace it. The underground reservoirs are being depleted. There is at least one area that has sunk slightly as a result. 3) People drink water out of plastic bottles and fill the landfills with them. Our distribution system in the water industry is one of the most efficient - how much gasoline does it take to get water to your house? None. How much for that bottled water?

    But other than those 2 issues I don't really see a problem with using water for plants or for anything else.

    A willow tree, on a hot day, can transpire 5000 gallons of water. The beautiful old weeping willow in my pasture may use more water per year than our household of 4 people.

    One large tamarisk can transpire 300 gallons per day. There are 3.3 million acres of tamarisk that need to be eradicated in the US.

    I also don't see a problem with judicious use of water to maintain a garden in areas where reasonable water resources exist. Granted, I do let the lawn suffer & everything else is on drip. :-)

    Looking at my current bill, I personally use 33 gallons of water per day in the winter. My bill is for 1,000 gallons in each of the winter months. My highest bill looks like it was for 24,000 gallons. Last summer we had more water than we knew what to do with the first half of the summer, but it looks like things dried up about August/September :)

    mad gallica, in NY you get plenty of rainfall to keep a lawn alive without irrigation. I was born in Upstate NY and lived there until I was 44, and then moved to North Central Florida. You cannot keep a lawn alive in my area of Florida without supplemental irrigation, especially St. Augustine grass, (which we were told was the best stuff to put in). Ha!!! WHAT a lie, and what a racket! The stuff should be illegal here, and in some areas of Florida, it is. Talk about something that needs tons of chemicals and water to look good. Bahia grass can survive without irrigation, but can still die if mowed and allowed to go to seed. It also is a sparse grass, so many noxious weeds fill in.

    My conclusion is that lawns are not suitable in my area and are a HUGE waste of water. We are on an aquafer, but we have been going through some drought periods also, and the population has increased. I've noticed many of our lakes are down quite a bit. Despite water restrictions that are in place for once a week watering, during certain hours, many of my neighbors water their lawns every day. It's absolutely ridiculous!

    We stopped watering our lawn in December, and are going to let the grass continue to die off. I am going to try a native groundcover, and with any luck, it will work out, and I will gradually replace all of the grass with groundcover. Once established, it needs no supplemental irrigation.

    My roses and camellias are the only plants that I water, with drip irrigation. I am training them to get by with less water.

    I hope I set enough of an example that others may alter their thinking, and go native. It's insane to waste water on a lawn, as well as the money involved in buying fertilizer, organic or otherwise, and then having to mow and blow each week. I've got better things to do....like enjoy my roses. I also do not want to turn my faucet on some day, and have nothing come out of it.

    I don't use much water for my garden, but I don't really know exactly how much, as we are on a well and so not metered. I do mulch and never sprinkle, but water only the things that need it. Lawns here can be allowed to go brown in the summer and revive in the fall just fine. I have a small one that I like for sitting on and playing with the kids.

    My husband likes to read about living off the grid and suchlike, and at one point we talked about building an underground cistern and collecting the rainwater from our roof. It's a remarkable technology, essentially giving you an underground pond of your very own to use.

    http://www.rainwaterclub.org/how.htm

    And wiki says that as long as the water is used where it's collected, it won't deplete the reserves there, but instead allow the water to percolate more slowly as it's used over time, rather than running off.

    It doesn't make sense for us here, but for people in droughty rainless situations it may be useful info.

    159 gallons would cover 16' x 16' area one inch deep. That would cover 3' radius circle one inch deep around 8 or 9 roses, or a 2' radius circle around 20 roses. If, as anntn6b wonders, that 159 gallons includes all commercial/industrial use, it doesn't seem that large. On the other hand, if someone waters a 1/8 acre lawn one inch per week, they're using on average 3 x 159 gal. per day plus whatever they use inside the house. So maybe there are enough lawn-waterers to make up for the non-waters. I don't seem to have to water our lawn. I couldn't water our roses for two months of drought at the end of last summer, and we were out of town for six weeks preceding. I did water with saved kitchen water, which was 3-6 gal per day.

    One other thing, water is naturally recycled. It runs downstream (as cweatherby said) or evaporates, and it rains back down on the earth. Of course, you might run out and things might die while you wait for it to come back. Some places get it back sooner than others. And so on.
