Water conservation has been
a fact of life on California’s Monterey Peninsula for decades. You may not
guess it looking at the beautiful greens of the Pebble Beach golf courses, but
go into the residential communities of Monterey, Carmel, Pacific Grove and
Seaside, and you’ll find drought-tolerant sage, lavender, fescue and succulents
where many communities have verdant lawns.
Water use on the Monterey Peninsula averages 70 gallons per person per day.
Compare that to a national average of 100 gallons. Water is limited in this
community not only due to its semi-arid climate but also because of legal
limits on its main source of supply, the Carmel River.
Restrictions on pumping from the Carmel River were put in place by the state in
part to protect a threatened subspecies of trout, the Central California Coast
Steelhead. Water use on the Monterey Peninsula decreased by more than 30
percent since the limitations were issued in the mid-1990s. In response to the
order, golf courses began using recycled water, residents and businesses
switched to low-flow toilets, and water rates went up for big users causing
them to cut back their use.
While the
rest of California scrambles to comply with Gov. Schwarzenegger’s call for a
20% statewide reduction in per capita water use by 2020, residents on
the Monterey Peninsula can breathe a sigh of relief – they’ve already achieved
it and then some.
But further cutbacks on the Carmel River are threatened, and the community’s
water provider, California American Water, must ask its customers to save even
more water.
Knowing that approximately 30% of residential water use goes to outdoor
watering, the company launched an aggressive outreach campaign, Spring Into
Action, in March of 2008, urging residents to delay turning on their
sprinklers.
Looking at past consumption records, the company determined that water use
varied most during the early months of spring, relative to the amount of
rainfall. When the weather starts to warm up and it isn’t raining, people
naturally want to water their landscape. But they often underestimate the level
of water saturation still remaining in the soil from winter rains.
Through award-wining television, newspaper and radio ads and direct mail
to its customers, California American Water spread the message to wait a few
more weeks before irrigating. It worked. The amount of water used per inch of
rainfall decreased dramatically from previous years with an approximate savings
of more than 400 acre-feet of water.
In addition to its public outreach efforts, California American Water provides
incentives in the form of $100 to $700 rebates for items such as
high-efficiency toilets, cistern systems and smart irrigation controllers, which
delay watering until the soil is actually dry. The company also visits homes
and businesses to check for leaks, develop individualized outdoor watering
schedules and make indoor water-saving recommendations.
Unique circumstances have given the Monterey Peninsula a head start on what is
fast becoming the norm for water utilities across the western states and even
in parts of the country where rain is not scarce. National interest in water
conservation and concerns over climate change are leading water providers
throughout the country to create an even stronger message to their customers
about the importance of preserving this precious resource.
