I don’t think about water
very much. I turn faucets on and off every day many times, and use water for a
variety of tasks that seem necessary to a good life – showers, cleaning hands,
washing dishes, making coffee. When water is in the news, it’s about too much
water, the floods of the century that seem to be happening every few years in
the Midwest.
Lately, though, I have been
doing experiments with water. What if I turn off the water in the shower
several times when I don’t need the spray? Can I save water that I would
normally dump down the drain by pouring some into a container? Can I use less
water when I wash dishes?
In all the houses of friends
and family I visit, in all the restaurants and workplaces I visit, an unending
supply of clean, drinkable water is an unspoken assumption. But that is one of
the great privileges of living in one of the world’s wealthiest countries.
It also is our great danger.
America uses too much water. The Colorado River, which provides drinking water
for 36 million Americans and irrigation for 15% of the nation’s crops, is so
overused that the water level in Lake Mead behind the Hoover Dam, the
country’s largest reservoir, is dropping to emergency levels. Seven states that
depend on Colorado River water have just agreed to voluntarily cut
their water usage. The days of virtually free unlimited water in the
Southwest are over.
Meanwhile, we have way too
much water in the Midwest. Both changes are connected to climate change, and so
might get worse for the next few decades. In neither region, in no region, are
Americans prepared for the basic changes in our water systems that global
warming has brought and will keep bringing.
Flushing the toilet
represents the largest use of water in an average American household, about 30%
of total daily usage. Older toilets use 3.6 gallons per flush, while the newer
so-called ultra-low-flow toilets use 1.6 gallons and even newer “high
efficiency toilets” use 1.3 gallons, multiplied by an average of more than 5
flushes per day per person. Showers last an average of 8 minutes at 2 gallons
per minute.
It is possible to
significantly reduce water usage by installing relatively cheap bits of
equipment which create no inconvenience: aerators for faucets and low-flow
shower heads. More expensive are modern toilets and high efficiency washers and
dishwashers.
The Alliance for Water
Efficiency makes further
suggestions for reducing water usage. They recommend what they call the “navy
shower”, in which you turn off the water while shampooing and washing, then
turn it on again. I’ve never been in the Navy, but this is how I shower,
probably saving about the half the water I would otherwise use. That’s easy.
Another suggestion they make is to collect the cold water that comes out of the
shower before it is hot enough to step into. Think about that: get a bucket,
turn the shower on so that some of the spray goes into the bucket, take the
bucket out when the shower is warm, use that water later for – what? Watering
plants? Washing dishes?
That’s an example of how
inconvenient it is to have limited water supply.
Two-thirds of people in
sub-Saharan Africa have no
water at all at home. In most of these countries, over 90% of the rural
population has no water at home. For many people, the nearest water supply is
more than 30 minutes away. One gallon of water weighs over 8 pounds. Imagine
needing to carry all the water for your household for half an hour.
Great improvements
have been made recently in providing access to water in poorer nations. The
proportion of the world’s people with access to “improved drinking water” has
risen from 76% in 1990 to 91% in 2015. One of the biggest improvements was in
China, where the number jumped from 67% to 95% among over 1 billion people.
Nearly 2
million Americans do not have access to clean running water. Naturally it
is poor minority communities who suffer most: Native Americans, rural blacks in
the South, Latino communities along the border with Mexico. But every
state has areas where people do not have indoor plumbing.
I have a small metal milk can
on my kitchen counter that holds about a gallon. I often pour water I have
already used into it. When it’s full, I use the water in my garden. That water
would have gone down the drain. If pouring it into my garden replaces other
water I would have used for that purpose, I might have saved money. Some months
we don’t use more than 2000 gallons, so our charge is flat, whether I save a gallon
here or there or not. When we use more than 2000, I’m reducing our payment
about 7 cents for every 100 gallons I don’t use. Water is extraordinarily cheap
for us.
My water saving experiment
was not useless. It is no solution to our coming water problems, but it began
to show me what water privilege means. Maybe it will help prepare me for a
future when our water privilege runs out.
