WATER
global issue of water and has for several
and a water scorecard that combines
what water use means to our business,
Water conservation has been a critical issue
at Cummins for some time. Since 2008,
the Company has collected water-use data
to support water conservation efforts at
sites throughout Cummins. In 2012, the
Company will further strengthen its water
management efforts by assessing risks at
priority locations in water-stressed areas in
addition to setting a company-wide water
conservation goal.
Since more than 60 percent of the
Company’s business is in international
markets, Cummins recognizes the
challenges associated with the rising
years focused on conserving water and
reducing wastewater discharges.
The Company continues to accelerate
our efforts in effective water management,
recognizing the growing significance of this
resource throughout our global footprint.
Last year, Cummins identified three
focus areas for water conservation at our
locations: grounds, facilities, and processes.
Cummins sites focused on these areas
for conservation opportunities and again
achieved positive results by calculating
their water balances (a formal exercise that
defines water intakes, uses, and discharges)
leading and lagging metrics.
In 2011, Cummins reduced water use
normalized for labor hours by 18 percent
from 2010 levels. That brought our total
labor-normalized water-use reduction to
45 percent since 2008.
Of perhaps even greater significance,
Cummins reduced absolute water use
in 2011 by approximately 5 percent or
60 million gallons.
However, the Company’s accelerated effort
in effective water management is about
more than just successful conservation
results. It is also about understanding
our communities and our environment.
In 2011, Cummins made significant strides
in developing this understanding by
conducting water management surveys
of sites across the Cummins’ enterprise.
By pairing local site knowledge with
global water availability data, Cummins
is able to prioritize efforts that will have
the greatest impact.
The Company is now conducting a
series of water source assessments at
our highest priority sites located in both
India and Mexico, two regions that face
water scarcity challenges.
