Drought can be a hit almost anywhere: how the five cities using water to run almost drought

Water scarcity is often seen as an issue for the American West, but the Northeast experience in 2024 suggests how severe drought can be in any part of the country.

Cities in the Northeast experienced a warm, dry summer in the second half of 2024 in many areas. Wildfire extinguished In many states that rarely see them.

By December, most areas Was experiencing moderate for severe droughtIn residents New York City And Bostan The use of their water was asked to reduce, while Philadelphia Due to the salt water coming over the Delaware River, it faced risk for its water supply.

Before drought, many people in the region were not ready for water shortage or even paying more attention to their use of water.

As the global temperature rises, there is more likely to experience in cities across America Hotter, Dryer Status Like this. They increase conditions evaporation, dry vegetation and soil and reduce groundwater tables.

Northeast drought This area was getting very low In the beginning of 2025, but communities across America should pay attention to what happened. They can learn from the experiences of cities that have faced major water supply crises – such as Cape Town, South Africa; São Paulo, Brazil; Melbourne, Australia; Las Vegas; And start planning now to avoid the worst effects of the new Orleans- and the most of the future droughts.

Lessons from cities that have seen the worst

Our new Analysis of the experiences of these five cities The water supply provides lessons about avoiding crisis or reducing effects through active policies and planning.

Many cities have faced major water supply crises in recent years. Perhaps the most famous example is “Day Zero” of Cap Town.

Three years after continuous drought in the region, Cape Town officials started an upside count in 2017. Day zero– The point at which the possibility of water supply will be so low that water will be closed in the neighborhood and residents will need to allocate water daily at public distribution points. Initially it was estimated to be in April 2018.

The water rate was increased, and Some houses set up flow restantsWhich will automatically limit the amount of water that can be used. Public awareness and conservation efforts cut water consumption into half, allowing the city to push its estimate back when the day will come to zero. And when the rain finally came in summer in the summer, Dey Zero was canceled.

Another example is Sao Paulo, who experienced a serious drought between 2013 and 2015. The city’s reservoirs were reduced to just 5% of their capacity, and the utility of water reduced the pressure in the water system to limit the use of water by the residents.

Water pricing adjustment was used Punish high water users and reward water conservationAnd a citieswide campaign demanded to raise awareness and encourage protection. As Cape Town, the crisis ended with heavy rains in 2016. Since then important investment has been made in the city’s water distribution infrastructure upgrade, preventing leaks and bringing water to the city from other river valleys.

Further plans may reduce losses

Experiences of Cape Town and Sao Paulo and other cities in our study- how water supply crisis can affect communities.

When major changes are made to reduce water consumption, they can do Impress people’s daily life and pocketbookRapidly designed conservation efforts can have harmful effects on poor and weak communities, which may have less alternatives in restrictions or shutoffs or a lack of ability to pay high prices for water, causing water And difficult options for homes can be forced to be forced to homes among other requirements.

Further plan allows for more thoughtful policy design.

For example, Las is struggling with Vegas Drought condition for the last two decadesDuring that time, the area was implemented Water conservation policies It focuses on the need for encouragement and even water consumption.

Since 2023, Las Vegas Valley is Water District Applied water rates This encourages protection and may vary with availability of water supply during drought. In its first year, policy 3 billion gallons saved And amidst other conservation efforts, the US $ 31 million was produced in fees used by programs for leak detection and repair. A state law now requires businesses and homeowners associations in the Las Vegas Valley Remove their decorative grass By the end of 2026.

Since 2002, the use of per capita water in Las Vegas Is canceled By an impressive 58%.

Solutions and strategies for future

Most of the cities we studied incorporated a variety of approaches to build water safety and from their community from drought-propagation-conversion-publishing. Real-time dashboard Cape is showing water usage and availability to invest in Town Analogy,

But we found that the most important changes came from the members of the community and supported efforts to conserve water and to invest in water protection, such as reducing lawn water.

There are also long -term functions that can help proof the drought, such as fixing or changing Water- and energy-intensive fixtures and structuresThis involves upgrading home appliances, such as rain, dishwasher and toilets, more water efficient and investing Indigenous and drought-toilet landscap,

Preference to green infrastructure, such as retention ponds and biosals, which help absorb rain when it falls and investing in water recycling can also bring diversity to the water supply.

Now taking these steps, beyond the next drought, you can prepare cities and reduce pain.
