n just under 500 days, we will reach the 2015 deadline
for the Millennium Development Goals. Some of those
goals will be met, and I hope that those involved will take
a moment to celebrate. But that isn’t the case for those of
us working in the area of sanitation.
We are among the furthest from achieving our MDG
target, which is to reduce by half the number of people
who don’t have access to improved sanitation. Falling
short of this target is a major disappointment, but we also
need to recognize that the indicator itself does not capture
the breadth of the sanitation challenge. Put simply: in
order to accelerate change that truly improves and saves
lives, we will need to change what we measure.
No doubt, providing people with access to toilets is a
critical step. However, what we have found over the years
since the MDGs were set is that mere access to toilets
does not result in safe sanitation. Toilets are necessary, but
not sufficient. Two more steps are required: people have to
use the toilets, and the waste contained by toilets must not
be released untreated into the environment, where it will
make people sick.
Many countries have made tremendous progress in
getting entire communities to commit to using toilets,
and there is now consensus within the sanitation sector
that ending open defecation is critical to saving lives
and thus must be a priority. We’ve learned that in some
communities there remain cultural and social barriers that
will require significant investments in behavior and social
norm change to overcome, but also that once households
commit to stopping open defecation, they can and will
invest in moving up the sanitation ladder when they are
offered products they want and can afford.
However, the public health problem can be severe even
when almost everyone is using a toilet. Although for
example Bangladesh, has reduced their rate of open

defecation by an amazing 97 percent, a 2011 study by the
World Bank’s Water and Sanitation Program estimated
that poor sanitation and hygiene still costs the Bangladeshi
economy up to $4.2 billion per year, equivalent to 6.3
percent of the country’s GDP in 2007. As populations
urbanize and informal settlements grow, so do the
challenges of urban sanitation.
Take Dhaka for example. The WSP collected data showing
that while 99 percent of the population in the capital use
toilets, only 2 percent of their waste is being treated. That
means that an astounding 98 percent of all the diseasecarrying pathogens in the human waste from that city are
being released into the environment. Those pathogens
are being piped into ditches, dumped into fields, leaked
out of sewer lines, and released into bodies of water from
overloaded treatment plants. It’s even happening right next
to the toilets that are supposed to protect people from this
dangerous waste. And so, people in Dhaka and in cities all
across the developing world are getting sick.
We need to start thinking about — and measuring —
our progress in a way that captures the full sanitation
challenge, one that captures that cities like Dhaka aren’t
today achieving sanitation levels nearing perfect, but rather
recognizes they have a long way to go. Fortunately, one
single indicator can capture this: the amount of untreated
fecal waste that gets released into the environment. A
commitment to reduce untreated waste would drive
the necessary investments in fecal sludge management
in urban and peri-urban areas, while complementing
investments to end open defecation in rural areas.
As the world turns its attention to creating new post2015 Sustainable Development Goals, I think it’s critical
that we set a target to measure and reduce the amount of
untreated waste. This one indicator could capture much
of the progress sought in the sanitation goals recently
proposed by the U.N. Open Working Group on the SDGs.
Some may think that it’s too difficult to measure untreated
waste within urban communities, especially informal
settlements. But I am encouraged by the great work
coming from partners like WSP, Center for Global Safe
Water, and GIZ, which are developing the tools and
processes needed to accurately measure untreated waste at
the city level. We are committed to working with these and
other partners to provide access to a full suite of tools and
processes that will deliver accurate and actionable results.
We are also working with partners to come up with new
tools and processes to reduce untreated waste, ranging
from how entrepreneurs can more efficiently empty pits
and septic tanks to how governments can provide enabling
environments that incent such entrepreneurs while
ensuring that the waste actually gets treated. Some of
