Water scarcity is often viewed as an issue for the arid American West, but the U.S. Northeast’s experience in 2024 shows how severe droughts can occur in just about any part of the country.
Cities in the Northeast experienced record-breaking drought conditions in the second half of 2024 after a hot, dry summer in many areas. Wildfires broke out in several states that rarely see them.
By December, much of the region was experiencing moderate to severe drought. Residents in New York City and Boston were asked to reduce their water use, while Philadelphia faced risk to its water supply due to saltwater coming up the Delaware River.
Before the drought, many people in the region weren’t prepared for water shortages or even paying much attention to their water use.
As global temperatures rise, cities throughout the U.S. are more likely to experience hotter, drier conditions like this. Those conditions increase evaporation, drying out vegetation and soil and lowering groundwater tables.
The Northeast drought was easing in much of the region in early 2025, but communities across the U.S. should take note of what happened. They can learn from the experiences of cities that have had to confront major water supply crises – such as Cape Town, South Africa; São Paulo, Brazil; Melbourne, Australia; Las Vegas; and New Orleans – and start planning now to avoid the worst impacts of future droughts.
Lessons from cities that have seen the worst
Our new analysis of these five cities’ experiences provides lessons on how to avoid a water supply crisis or minimize the effects through proactive policies and planning.
Many cities have had to confront major water supply crises in recent years. Perhaps the most well-known example is Cape Town’s “Day Zero.”
After three years of persistent drought in the region, Cape Town officials in fall 2017 began a countdown to Day Zero – the point at which water supplies would likely run so low that water would be turned off in neighborhoods and residents would need to fetch a daily allocation of water at public distribution points. Initially it was forecast to occur in April 2018.
Water rates were raised, and some households installed flow restrictors, which would automatically limit the amount of water that could be used. Public awareness and conservation efforts cut water consumption in half, allowing the city to push back its estimate for when Day Zero would arrive. And when the rains finally came in summer 2018, Day Zero was canceled.
A second example is São Paulo, which similarly experienced a severe drought between 2013 and 2015. The city’s reservoirs were reduced to just 5% of their capacity, and the water utility reduced the pressure in the water system to limit water use by residents.
Water pricing adjustments were used to penalize high water users and reward water conservation, and a citywide campaign sought to increase awareness and encourage conservation. As in Cape Town, the crisis ended with heavy rains in 2016. Significant investments have since been made in upgrading the city’s water distribution infrastructure, preventing leaks and bringing water to the city from other river basins.
Planning ahead can reduce the harm
The experiences of Cape Town and São Paulo – and the other cities in our study – show how water supply crises can affect communities.
When major changes are made to reduce water consumption, they can affect people’s daily lives and pocketbooks. Rapidly designed conservation efforts can have harmful effects on poor and vulnerable communities that may have fewer alternatives in the event of restrictions or shutoffs or lack the ability to pay higher prices for water, forcing tough choices for households between water and other necessities.
Planning ahead allows for more thoughtful policy design.
For example, Las Vegas has been grappling with drought conditions for the past two decades. During that time, the region implemented water-conservation policies that focus on incentivizing and even requiring reduced water consumption.
Since 2023, the Las Vegas Valley Water District has implemented water rates that encourage conservation and can vary with the availability of water supplies during droughts. In its first year alone, the policy saved 3 billion gallons of water and generated US$31 million in fees that can be used by programs to detect and repair leaks, among other conservation efforts. A state law now requires businesses and homeowner associations in the Las Vegas Valley to remove their decorative grass by the end of 2026.
Since 2002, per capita water use in Las Vegas has dropped by an impressive 58%.
Solutions and strategies for the future
Most of the cities we studied incorporated a variety of approaches to building water security and drought-proofing their community – from publishing real-time dashboards showing water use and availability in Cape Town to investing in desalination in Melbourne.
But we found the most important changes came from community members committing to and supporting efforts to conserve water and invest in water security, such as reducing lawn watering.

There are also longer-term actions that can help drought-proof a community, such as fixing or replacing water- and energy-intensive fixtures and structures. This includes upgrading home appliances, such as showers, dishwashers and toilets, to be more water efficient and investing in native and drought-tolerant landscaping.
Prioritizing green infrastructure, such as retention ponds and bioswales, that help absorb rain when it does fall and investing in water recycling can also diversify water supplies.
Taking these steps now, ahead of the next drought, can prepare cities and lessen the pain.

Graffiti Cleanup Transforms Oceanwide Plaza
LOS ANGELES — The unfinished skyscrapers known as downtown Los Angeles’ “Graffiti Towers” have reached a visible milestone: most of the exterior tagging has been removed, although completing the long-stalled Oceanwide Plaza development remains a separate challenge.
City officials celebrated the cleanup November 12. According to the mayor’s office, crews cleared graffiti from roughly 250 balconies across the three-tower complex opposite Crypto.com Arena and near the Los Angeles Convention Center. Remaining work has included touch-ups on windows and other exterior areas.
Oceanwide Plaza was envisioned as a mixed-use destination with residences, a luxury hotel, shops and restaurants. Construction stopped in 2019 after Beijing-based developer Oceanwide Holdings could no longer finance the project.
In early 2024, trespassers covered the unfinished towers with graffiti, turning them into an internationally recognized sight. The property also attracted dangerous stunts and heightened concerns about security.
The development entered bankruptcy in February 2024. This July, a bankruptcy court approved a purchase arrangement involving KPC Square, a joint venture between KPC Group and Lendlease. Graffiti removal began while the acquisition was still pending.
What Comes Next for LA’s Graffiti Towers?
The partnership is targeting a January 2027 closing, according to the Los Angeles Business Journal. Financing, a construction contract and required approvals remain important steps before the development can be completed.
For downtown residents and businesses, the cleanup marks tangible progress at a prominent property. However, it does not mean the towers are ready to open, and no firm opening date has been announced.

David Crosthwait: The Engineer Behind Indoor Comfort
David Crosthwait helped solve the challenges of heating large buildings, including Radio City Music Hall. Explore his inventions and lasting engineering legacy.
Forgotten Genius | STM Daily News
When audiences enter New York’s Radio City Music Hall, they notice the stage, the lights, and the sweeping auditorium. The engineering that keeps the building comfortable rarely receives applause.
One of the people behind that comfort was David Nelson Crosthwait Jr., a Black engineer and inventor whose work helped advance heating, ventilation, and temperature control in large buildings.
His career offers a reminder that some of the most useful inventions work quietly around us.
Solving the Problem of Heating Large Buildings
Heating a large building takes more than producing enough heat. Different areas can have different needs: one side may face bitter wind while another receives warming sunlight. Delivering the right amount of heat throughout the building requires careful control.
Crosthwait devoted much of his career to those challenges. A Purdue University engineering graduate, he worked for the C.A. Dunham Company, developing equipment and systems for heating and ventilation.
His inventions included improvements to boilers, thermostat controls, and vacuum pumps. These components helped engineers manage the movement and regulation of heat in larger buildings.
One example appears in U.S. Patent No. 1,727,965, granted in 1929. The patent describes a vacuum steam-heating system designed to serve different sections of a building at different steam pressures. That allowed the system to address varying heating needs while using a shared steam source.
Behind the technical drawing was a practical question: How could one building provide comfortable conditions in spaces that needed different amounts of heat?
His Connection to Radio City Music Hall
Crosthwait’s best-known projects included designing the steam-heating system for Radio City Music Hall at Rockefeller Center.
It was a fitting assignment for an engineer whose expertise centered on the demands of large buildings. While performers entertained audiences, the systems behind the scenes helped make the experience comfortable.
His contributions extended across a substantial body of work. The National Inventors Hall of Fame credits him with 39 U.S. patents and 80 international patents, spanning heating, refrigeration, controls, and other technologies.
Sharing Knowledge and Breaking Barriers
Crosthwait also helped other engineers learn. He wrote technical material, contributed to engineering guides, and later taught steam-heating theory and control systems at Purdue.
In 1971, he became the first Black Fellow of the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Purdue awarded him an honorary doctorate in 1975, and the National Inventors Hall of Fame inducted him in 2014.
His legacy rests in the practical details of engineering: controlling pressure, improving equipment, and making complicated systems work together.
The next time you settle into a comfortable auditorium on a cold evening, consider the ingenuity behind that warmth. David Crosthwait helped make indoor comfort an engineering achievement worth remembering.

The House That Hosts: When Your Home Becomes Your Holiday Entertaining Partner
The House That Hosts: There’s a special pleasure in opening your home for the holidays to share the menu you’ve imagined, welcome guests to the glow of a room ready for company and enjoy the anticipation of familiar faces at the door. This year, make sure the house itself can lend a hand.
The House That Hosts: When Your Home Becomes Your Holiday Entertaining Partner
(Feature Impact) There’s a special pleasure in opening your home for the holidays to share the menu you’ve imagined, welcome guests to the glow of a room ready for company and enjoy the anticipation of familiar faces at the door. Every detail is an opportunity to make the loved ones you’ve invited feel especially welcome.
This year, make sure the house itself can lend a hand.
From the kitchen to the living room to the guest bathroom, residential technology offers new ways to turn a host’s imagination into a memorable experience. The best innovations don’t take over the occasion. They help the person bringing everyone together make it extraordinary.
Nor does a home need an elaborate network of connected gadgets. A few well-chosen technologies can make a difference. Explore these ideas from the bathroom design and technology experts at TOTO to level up the different hosting areas of your home as you prepare to gather with family and friends this holiday season.
The Kitchen: Bringing Something Extraordinary to the Table
The holidays invite a little culinary ambition, and today’s kitchens are borrowing a few tricks from professional chefs.
Imagine presenting a beef tenderloin cooked to a perfect rosy pink from edge to edge, thanks to the precision of sous vide cooking. Or bringing a platter of roasted root vegetables to the table, their edges beautifully caramelized and their centers tender, prepared in a steam-convection oven. On an induction cooktop, precise, responsive heat helps turn fresh mushrooms into a golden, savory accompaniment.
These technologies put sophisticated techniques within reach of adventurous home cooks, opening the door to new preparations and dishes worthy of special occasions. Experiment with new flavors and rich cuisines that fill your home with enticing aromas and your guests with awe at the first bite.
Nothing says “happy holidays” quite like watching guests discover what you’ve created for them.
The Living Area: Setting the Stage for Connection
Holiday gatherings have a rhythm all their own. The first arrivals are greeted with excitement, conversations pick up where they left off months (or years) prior, and before long, the room is filled with laughter and the pleasure of being together.
Today’s smart lighting systems allow hosts to create and schedule scenes that shift from the sparkle of a festive welcome to the softer, golden glow of an intimate evening. Multiroom wireless audio systems can bring lively music into the kitchen while keeping it a gentle accompaniment to conversation in the living area. Digital art displays can turn a television screen into a gallery of artwork chosen to complement the celebration, bringing holidays past to life as loved ones mingle in the present.
Successful holiday entertainment engages people not merely as observers, but participants. A short film could start an inspiring conversation, the right music might get people dancing and atmospheric visual-audio experiences, like a crackling fireplace or soft snowstorm, can create a relaxing seasonal backdrop for shared activities.
With the atmosphere changing quietly in the background, no one needs to interrupt a favorite story to adjust the lights or lower the music. The host can simply enjoy the company they’ve brought together.
The Bathroom: The Art of Personal Comfort
The most gracious hosts think beyond the rooms where guests gather. Fresh towels, fragrant soaps and a few unexpected comforts can make the guest bathroom feel every bit as welcoming as the rest of the home.
Technology adds a new dimension to that hospitality. Consider a TOTO WASHLET bidet seat, which offers the welcome warmth of a heated seat, the refreshing pleasure of warm-water cleansing and the soothing comfort of warm-air drying. It’s an unexpected luxury that makes an everyday experience feel special.
Hosts can choose an option that complements their home’s character. The S2 offers inviting simplicity with convenient side-panel controls. The sleek S5 pairs contemporary elegance with a wireless remote. Meanwhile, the S7A adds a touch of theater with a lid that opens automatically, a softly glowing nightlight and personalized cleansing settings.
Even the housekeeping benefits from a little ingenuity through automatic PREMIST and EWATER+: One mists the toilet bowl before use to help keep it cleaner, while the other cleans the cleansing wand and, on select models, the bowl itself with electrolyzed water.
It’s another way a thoughtful host can anticipate guests’ needs and make them feel wonderfully welcome.
Long after the last guest has departed, what lingers isn’t the sophistication of the house. It’s the meal that inspired compliments, the conversations no one wanted to end and the little surprises that made everyone feel at home.
Those are the moments that make holiday entertaining special. Behind each one is a host whose warmth, creativity and attention to detail made it possible, with a little help from the house. Explore more sophisticated bathroom upgrade ideas for the holidays and beyond at TOTOUSA.com.
