In 2015, the American Water Works Association
named Big Sky’s drinking water the best-tasting in the country. Pulled from
deep underground, our water contains sweet-tasting minerals like calcium and
magnesium. These minerals are perfectly healthy for human consumption, but they
can wreak havoc on our home appliances. They can shorten the lifespan of
everything from showerheads to hot-water heaters, and they give our teapots and
faucets that unattractive white, crusty coating. Because of these minerals, our
water is known as “hard water.”
To soften it, we often install filtration
systems that utilize salt, but the time has come for a change. Why, you might
wonder, should you care at all about your water-filtration system? As long as
the water is safe to drink, what is the difference?
Great question.
For one, salt-based filtration systems waste
tons of water—literally. The Wilson Hotel recently installed a new, salt-less
system and their water savings are estimated at 250,000 gallons annually.
That’s a lot of water, and a huge cost savings to boot.
In a salt-based system, healthy calcium and
magnesium are replaced by equal parts of sodium, and the significant volume of
water used in this process is flushed down the drain. This produces gallons of
waste before any water ever reaches our showers, washers or toilets, and turns
our high-quality drinking water into unpalatable salt water. Users of
salt-water systems must then install another filtration system under their
sinks which removes the just-added salt, as well as all of the beneficial
minerals in the water, creating water that lacks any mineral content and isn’t
healthy for long-term consumption. The result is a series of filtration systems
that waste a significant amount of water, are costly to maintain and provide
poor-quality drinking water.
So, what is the solution? There is now an
innovative water-conditioning media that doesn’t require salt or the
consumption of water. With this system, hard water undergoes nucleation in the
pressure vessel, transforming calcium bicarbonate into an aragonite form of
calcium carbonate crystals. In layman’s terms, this salt-free system softens
water without removing beneficial minerals or wasting water. You’ll get all the
“best-tasting drinking water in the country” without any waste. They call that
a win-win situation.
“Residential users can expect to save about
$500 a year,” says Peter Manka, principal water resource engineer at Alpine
Water in Big Sky. “Salt-free systems cost a fraction of what salt-based
softeners cost. There’s less maintenance, no moving parts, no salt to buy and
less time and energy wasted. Plus they’ll be using—and paying for—less water.”
According to Manka, these systems save about
10,000 gallons of water and 800 pounds of salt per average household annually.
With the savings in the cost of water, salt, filter replacements and
maintenance, replacing your salt based system can pay for itself in three to
four years.
Additionally, that’s a lot less salt. While
the Wilson is estimated to save 250,000 gallons of water annually, they’ll also
save up to 50,000 pounds of salt. When salt is used to treat water, a portion
of that salt ends up back in the environment, contaminating surface water,
decreasing the effectiveness of our wastewater treatment system and potentially
polluting the watershed. Salt in these quantities is not naturally occurring,
and is therefore another unwanted result of salt-intensive softening.
While salt-water softening is still the norm,
numerous commercial and residential properties in Big Sky have installed this
relatively new salt-free technology. And why not? It saves money, it saves
water and it improves overall watershed health and resilience. They call that a
win-win-win.
