Most populated city in North America and there’s very little coverage.

I never imagined the disconnect between news and reality could get this
wide.
And I made Don’t Look Up.

Mexico City could run out of water within weeks.
"Day Zero" is counting down to June 26th. The whole country is in #drought
conditions, and huge parts are in Extreme drought. A society can't run
without water, and that could become a reality very soon in some regions.

World / Climate
One of the world’s biggest cities may be just months away from running out
of water

Alejandro Gomez has been without proper running water for more than three
months. Sometimes it comes on for an hour or two, but only a small trickle,
barely enough to fill a couple of buckets. Then nothing for many days.

Gomez, who lives in Mexico City’s Tlalpan district, doesn’t have a big storage
tank so can’t get water truck deliveries — there’s simply nowhere to store it.
Instead, he and his family eke out what they can buy and store.

When they wash themselves, they capture the runoff to flush the toilet. It’s
hard, he told CNN. “We need water, it’s essential for everything.”


Water shortages are not uncommon in this neighborhood, but this time feels
different, Gomez said. “Right now, we are getting this hot weather. It’s even
worse, things are more complicated.”

Mexico City, a sprawling metropolis of nearly 22 million people and one of the
world’s biggest cities, is facing a severe water crisis as a tangle of problems
— including geography, chaotic urban development and leaky infrastructure
— are compounded by the impacts of climate change.

Years of abnormally low rainfall, longer dry periods and high temperatures
have added stress to a water system already straining to cope with increased
demand. Authorities have been forced to introduce significant restrictions on
the water pumped from reservoirs.

“Several neighborhoods have suffered from a lack of water for weeks, and
there are still four months left for the rains to start,” said Christian Domínguez
Sarmiento, an atmospheric scientist at the National Autonomous University
of Mexico (UNAM).

Politicians are downplaying any sense of crisis, but some experts say the
situation has now reached such critical levels that Mexico City could be
barreling towards “day zero” in a matter of months — where the taps run dry
for huge swaths of the city.

Historic lows
Densely populated Mexico City stretches out across a high-altitude lake bed,
around 7,300 feet above sea level. It was built on clay-rich soil — into which it
is now sinking — and is prone to earthquakes and highly vulnerable to
climate change. It’s perhaps one of the last places anyone would choose to
build a megacity today.

The Aztecs chose this spot to build their city of Tenochtitlan in 1325, when it
was a series of lakes. They built on an island, expanding the city outwards,
constructing networks of canals and bridges to work with the water.



But when the Spanish arrived in the early 16th century, they tore down much
of the city, drained the lakebed, filled in canals and ripped out forests. They
saw “water as an enemy to overcome for the city to thrive,” said Jose Alfredo
Ramirez, an architect and co-director of Groundlab, a design and policy
research organization.

Their decision paved the way for many of Mexico City’s modern problems.
Wetlands and rivers have been replaced with concrete and asphalt. In the
rainy season, it floods. In the dry season, it’s parched.

Around 60% of Mexico City’s water comes from its underground aquifer, but
this has been so over-extracted that the city is sinking at a frightening rate —
around 20 inches a year, according to recent research. And the aquifer is not
being replenished anywhere near fast enough. The rainwater rolls off the
city’s hard, impermeable surfaces, rather than sinking into the ground.

The rest of the city’s water is pumped vast distances uphill from sources
outside the city, in an incredibly inefficient process, during which around
40% of the water is lost through leaks.

The Cutzamala water system, a network of reservoirs, pumping stations,
canals and tunnels, supplies about 25% of the water used by the Valley of
Mexico, which includes Mexico City. But severe drought has taken its toll.
Currently, at around 39% of capacity, it’s been languishing at a historic low.

“It’s almost half of the amount of water that we should have,” said Fabiola
Sosa-Rodríguez, head of economic growth and environment at the
Metropolitan Autonomous University in Mexico City.

In October, Conagua, the country’s national water commission, announced it
would restrict water from Cutzamala by 8% “to ensure the supply of drinking
water to the population given the severe drought.”

Just a few weeks later, officials significantly tightened restrictions, reducing
the water supplied by the system by nearly 25%, blaming extreme weather
conditions.

“Measures will have to be taken to be able to distribute the water that
Cutzamala has over time, to ensure that it does not run out,” Germán Arturo
Martínez Santoyo, the director general of Conagua, said in a statement at the
time.

Around 60% of Mexico is experiencing moderate to exceptional drought,
according to a February report. Nearly 90% of Mexico City is in severe
drought — and it’s set to get worse with the start of the rainy season still
months away.

“We are around the middle of the dry season with sustained temperature
increases expected until April or May,” said June Garcia-Becerra, an assistant
professor in engineering at the University of Northern British Columbia.

Natural climate variability heavily affects this part of Mexico. Three years of
La Niña brought drought to the region, and then the arrival of El Niño last
year helped deliver a painfully short rainy season that failed to replenish the
reservoirs.

The world’s largest lakes are shrinking dramatically, and scientists say they
have figured out why
But the long-term trend of human-caused global warming hums in the
background, fueling longer droughts and fiercer heat waves, as well as
heavier rains when they do arrive.

“Climate change has made droughts increasingly severe due to the lack of
water,” said UNAM’s Sarmiento. Added to this, high temperatures “have
caused the water that is available in the Cutzamala system to evaporate,” she
said.

Last summer saw brutal heat waves roil large parts of the country, which
claimed at least 200 lives. These heat waves would have been “virtually
impossible” without climate change, according to an analysis by scientists.

The climate impacts have collided with the growing pains of a fast-expanding
city. As the population booms, experts say the centralized water system has
not kept pace.

‘Day zero?’
The crisis has set up a fierce debate about whether the city will reach a “day
zero,” where the Cutzamala system falls to such low levels that it will be
unable to provide any water to the city’s residents.

Local media widely reported in early February that an official from a branch
of Conagua said that without significant rain, “day zero” could arrive as early
as June 26.

But authorities have since sought to assure residents there will be no day
zero. In a press conference on February 14, Mexican President Andrés
Manuel López Obrador said that work was underway to address the water
problems. Mexico City’s mayor, Martí Batres Guadarrama, said in a recent
press conference that reports of day zero were “fake news” spread by
political opponents.

Conagua declined CNN’s interview requests and did not answer specific
questions on the prospect of a day zero.

But many experts warn of a spiraling crisis. Mexico City could run out of
water before the rainy season arrives if it carries on using it in the same way,
Sosa-Rodríguez said. “It’s probable that we will face a day zero,” she added.

This doesn’t mean a complete collapse of the water system, she said,
because the city isn’t dependent on just one source. It won’t be the same as
when Cape Town in South Africa came perilously close to running totally dry
in 2018 following a severe multi-year drought. “Some groups will still have
water,” she said, “but most of the people won’t.”

Raúl Rodríguez Márquez, president of the non-profit Water Advisory Council,
said he doesn’t believe the city will reach a day zero this year — but, he
warned, it will if changes are not made.

“We are in a critical situation, and we could reach an extreme situation in the
next few months,” he told CNN.

‘I don’t think anyone is prepared’
For nearly a decade, Sosa-Rodríguez said she has been warning officials of
the danger of a day zero for Mexico City.

She said the solutions are clear: Better wastewater treatment would both
increase water availability and decrease pollution, while rainwater harvesting
systems could capture and treat the rain, and allow residents to reduce their
reliance on the water network or water trucks by 30%.

Fixing leaks would make the system much more efficient and reduce the
volume of water that has to be extracted from the aquifer. And nature-based
solutions, such as restoring rivers and wetlands, would help provide and
purify water, she said, with the added advantage of greening and cooling the
city.

In a statement on its website, Conagua said it is undertaking a 3-year project
to install, develop and improve water infrastructure to help the city cope with
decreases in the Cutzamala system, including adding new wells and
commissioning water treatment plants.

But in the meantime, tensions are rising as some residents are forced to cope
with shortages, while others — often in the wealthier enclaves — remain
mostly unaffected.

“There is a clear unequal access to water in the city and this is related to
people’s income,” Sosa-Rodríguez said. While day zero might not be here yet
for the whole of Mexico City, some neighborhoods have been grappling with
it for years, she added.

Amanda Martínez, another resident of the city’s Tlalpan district, said for
people here, water shortages are nothing new. She and her family often have
to pay more than $100 for a tank of water from one of the city’s water trucks.
But it’s getting worse. Sometimes more than two weeks can go by without
water and she fears what may be coming, she told CNN.

“I don’t think anyone is prepared.”

CNN’s Laura Paddison and Jack Guy reported from London, and Fidel
Gutiérrez reported from Mexico City.

Houston TX getting rain again today.
heaven forbid the hurricane season starts again.
Houston had three 1000 year floods in one year,
home insurance has topped $4590 a year since then.
any more any it will effect prices nation wide....
