Long Island Water Main Breaks After January 2026 Deep Freeze: What Homeowners Need to Know

If your water turned brown, pressure dropped, or you noticed crews digging up streets in January 2026, you're not alone. According to an official announcement from the Suffolk County Water Authority (SCWA), crews responded to 224 water main breaks since January 1st—more than double the 101 breaks repaired during the same period last year.

This represents the highest number of breaks in a single month since January 2018, when 268 failures were recorded. Towns from Massapequa to Lindenhurst experienced infrastructure failures as aging pipes couldn't withstand the extreme temperature swings during what SCWA officials called a "Deep Freeze."

Homeowners in Wantagh, Oceanside, and surrounding areas woke up to discolored water, icy sidewalks, and emergency repair crews blocking roads. Here's what happened, which areas were hit hardest, and what you can do if your water quality still hasn't recovered.

Why the Deep Freeze Caused 224 Water Main Breaks

According to SCWA's official statement, the authority maintains 6,000 miles of water mains across Suffolk County, with much of the infrastructure still made of brittle cast iron from the 1960s and 1970s. The combination of deep frost and aging materials created the perfect storm.

"Our crews have been nothing short of heroic. Working through the night in freezing temperatures, often in brutal conditions, they are tirelessly repairing breaks and restoring water service to our customers as quickly as possible."

— Charlie Lefkowitz, SCWA Chairman

When temperatures rapidly warmed in early February, the freeze-thaw cycle created hydraulic shocks that caused even more failures. Brendan Warner, SCWA Director of Construction and Maintenance, stated: "Our crews have faced a difficult winter, but they remain committed. We'll keep working until the cold subsides and the rate of breaks slows down."

SCWA crews worked around the clock to repair breaks, but the sheer volume—224 incidents in just one month—meant some neighborhoods waited days for normal service to resume.

Which Long Island Towns Were Hit Hardest?

According to South Shore Press reporting, water main breaks occurred throughout Suffolk County during January 2026, with active breaks monitored or repaired in communities including Lindenhurst, West Islip, Bay Shore, Islip Terrace, Coram, Ridge, and Sound Beach.

Based on SCWA service disruption reports and local news coverage, these areas saw the most significant impacts:

Massapequa

A major break on Merrick Road caused water service interruptions for homes along Park Boulevard and surrounding streets. Crews replaced a 50-year-old section of pipe that had previously leaked multiple times.

Residents near Massapequa High School reported rusty, orange-colored water for several days after the repair—a common issue when sediment gets stirred up during emergency work. This is the same iron contamination problem we've documented in Massapequa's aging infrastructure.

Wantagh

The intersection of Waterbury Drive and Wantagh Avenue experienced a significant break that flooded nearby properties. The frozen water created dangerous ice patches on sidewalks, forcing the town to close the intersection to traffic.

Homeowners in the Wantagh Woods neighborhood noticed low water pressure for nearly a week as SCWA isolated the damaged section and rerouted service.

Oceanside

A break on Waukena Avenue caused extensive flooding and icing near the Oceanside Recreation Center. Emergency crews had to excavate in freezing conditions, and residents reported discolored water lasting over 72 hours.

The pipe that failed had been flagged for replacement in SCWA's 2025 infrastructure plan but hadn't yet been upgraded.

Lindenhurst and Union Area

Multiple breaks in the Lindenhurst distribution network caused intermittent service disruptions. Homes near Wellwood Avenue and surrounding blocks experienced cloudy water and reduced pressure.

SCWA prioritized high-traffic areas like North Lindenhurst Middle School and the commercial district along Montauk Highway, but residential streets took longer to restore.

Why Your Water Might Still Look Brown or Rusty

Even after SCWA repairs a water main break, homeowners often see discolored water for days. Here's why:

Sediment disturbance: When crews shut off water, drain pipes, and restore service, the hydraulic shock stirs up rust, iron, and mineral deposits that have built up inside aging pipes over decades. This sediment gives water a brown, yellow, or orange tint.

Flushing delays: SCWA typically flushes hydrants after a repair, but if your home is far from the break site, sediment can linger in your household plumbing for a week or more.

Old pipes in your home: If your house was built before 1980 and still has original galvanized steel or copper pipes, interior corrosion can make the problem worse. Water main work elsewhere in the neighborhood can dislodge buildup inside your own pipes. We covered this exact issue in our guide on Shirley's sediment problems after Floyd Road pipe replacement.

Is Discolored Water Safe to Drink?

According to the Suffolk County Water Authority's FAQ page, brown or rusty water from sediment disturbance is not a health hazard. The discoloration comes from naturally occurring iron and manganese—minerals that don't pose a health risk at the levels typically seen after a main break.

However, the water may taste metallic or unpleasant, and it can stain laundry, dishes, and plumbing fixtures.

If you have discolored water:

• Run cold water taps for 5-10 minutes to flush sediment from your pipes
• Avoid doing laundry until water runs clear (iron stains are hard to remove from clothing)
• Check with neighbors—if they have clear water, the issue is likely inside your home's plumbing
• Contact SCWA at (631) 698-9500 if discoloration lasts more than 48 hours after flushing

The Hidden Danger: Road Salt Contamination

The Deep Freeze didn't just cause pipe breaks—it also led to heavy applications of road salt and brine to keep highways and local streets safe. While necessary for winter safety, this creates a secondary water quality problem.

Long Island sits on a sole-source aquifer, meaning all drinking water comes from underground. According to the EPA's Safe Drinking Water Act, sole-source aquifers receive special federal protection because contamination would create a significant public health hazard.

Road salt dissolves into runoff, percolates through soil, and eventually reaches the aquifer. High sodium and chloride levels can make water taste salty and may pose health risks for people on low-sodium diets.

SCWA monitors salt levels, but contamination can take weeks or months to show up in test results. Homeowners with private wells are especially vulnerable, as well water isn't regulated the same way public systems are.

Why Aging Pipes Keep Breaking

SCWA manages over 6,000 miles of water mains across Suffolk County, according to the authority's infrastructure data. Many sections were installed in the 1960s and 1970s, when transite (asbestos-cement) and cast iron pipes were standard.

Chairman Charlie Lefkowitz stated: "While these upgrades have made sections of the system more resilient, much of the infrastructure is still made of brittle cast iron, which is more prone to breaking under extreme conditions."

According to EPA infrastructure guidelines, these materials were considered cutting-edge at the time, but they have a lifespan of 50-75 years. We're now well past that point, and extreme weather events like the January 2026 Deep Freeze expose the weaknesses.

SCWA has an ongoing pipe replacement program, regularly replacing 20-30 miles of older cast iron pipe each year with newer, more durable ductile iron. However, with limited budgets and thousands of miles to upgrade, breaks will continue. The towns affected in January 2026 are just the latest examples—every winter freeze brings more failures.

What Homeowners Can Do Now

You can't control when SCWA replaces aging infrastructure in your neighborhood, but you can protect your home's water quality today:

1. Install Whole-Home Water Filtration

A whole-house water filtration system targets sediment, rust, chlorine, and other contaminants before they reach your faucets, showers, and appliances.

Unlike pitcher filters or faucet attachments, a whole-home system protects every water outlet in your house. That means cleaner drinking water, better-tasting coffee and tea, softer skin and hair in the shower, and longer-lasting water heaters and washing machines.

pHountain's Nell Whole-House Filtration System is designed specifically for Long Island water challenges. It targets:

• Sediment and rust from aging pipes (like what caused brown water after the Deep Freeze breaks)
• Chlorine added by SCWA for disinfection
• Iron and manganese that cause staining
• PFAS (forever chemicals) increasingly found in Long Island aquifers
• Hard water minerals that damage appliances and leave soap scum

The Nell system requires no salt, no electricity, and minimal maintenance—just an annual filter change. It's built by our in-house team right here in Islip, and we've installed over 2,000 systems for Long Island families since 2010.

2. Test Your Water (It's Free)

Most homeowners have no idea what's actually in their tap water. SCWA's annual reports show regional averages, but your specific block—especially if you're near a recent main break—could have different contaminant levels.

pHountain offers free in-home water testing for Long Island residents. We test for:

• Iron, manganese, and sediment (causes discoloration)
• Hardness (calcium and magnesium that damage appliances)
• Chlorine (taste and odor issues)
• pH levels (acidic water corrodes pipes)
• Total dissolved solids (overall water quality)

Testing takes about 20 minutes. Our technician brings lab-grade equipment to your home, runs the tests on-site, and explains the results in plain English—no pressure, no sales pitch. Schedule your free test today.

3. Flush Your Pipes After Any Service Disruption

Anytime SCWA shuts off water in your area—whether for a main break, planned maintenance, or flushing—sediment gets stirred up. Here's how to clear it quickly:

• Turn on cold water taps only (hot water can lock sediment into your water heater)
• Start with the tap farthest from your water meter (usually an upstairs bathroom)
• Let it run for 5-10 minutes or until water runs clear
• Move to the next farthest tap and repeat
• Finish with taps closest to the meter (kitchen sink, basement utility sink)

This process pushes sediment out through your household plumbing instead of letting it settle in pipes or appliances.

The Problem: Bottled Water Isn't the Answer

We see this all the time across Long Island. Families don't trust their tap water, so they buy cases of Poland Spring at Stop & Shop every week.

Here's the math on that:

As we broke down in our detailed analysis of bottled water costs on Long Island, you're literally throwing money away. The average Long Island family spends enough on bottled water over 10 years to buy a used car.

And here's the kicker: you're not even getting "pure" water. According to a 2024 Columbia University study published in the Proceedings of the National Academy of Sciences, bottled water contains an average of 240,000 detectable plastic fragments per liter—far more than previously thought.

You're not drinking "pure mountain spring water"—you're drinking tiny plastic particles that leached from the bottle. We covered this issue in depth in our guide on why Long Island families should stop paying for plastic water.

Will This Happen Again?

Yes. Cold snaps like the January 2026 Deep Freeze are becoming more common due to climate variability. Polar vortex events—where Arctic air plunges south—can happen multiple times per winter.

SCWA is working to replace the most vulnerable sections of pipe, but with thousands of miles of aging infrastructure, it will take decades to fully upgrade the system. In the meantime, homeowners need to take their water quality into their own hands.

How the January 2026 Deep Freeze Compares to Past Events

Long Island has experienced severe winter weather before, but the January 2026 Deep Freeze stands out. According to SCWA's official data:

The 224 breaks reported in January 2026 represent more than double the same period in 2025 (101 breaks), though still below the record 268 breaks seen during the January 2018 Bomb Cyclone. This reflects both the severity of the cold and the deteriorating state of Long Island's aging water infrastructure.

What SCWA Is Doing About It

The Suffolk County Water Authority has committed over $50 million annually to infrastructure improvements, including:

• Replacing transite and cast iron mains with modern ductile iron
• Upgrading pumping stations and reservoirs
• Installing leak detection technology to catch failures before they become emergencies
• Expanding the North Fork pipeline project (currently delayed due to legal disputes with the Town of Riverhead)

While these efforts will improve the system long-term, the backlog of aging pipes means breaks will continue for years to come.
