Buffalo, New York Water Outage Today

Buffalo tap water system, by the numbers

Buffalo Water Authority is the water system EPA lists for Buffalo, serving about 276,000 people. Customers know it as Buffalo Water; the name on your bill is the one to call.

What feeds the taps in Buffalo

Buffalo drinks surface water. Buffalo Water Authority draws it from Lake Erie and treats it before it goes into the distribution system. Treatment points named in EPA's facility list include Colonel Ward Water Treatment Plant. After treatment the water is held in 4 storage tanks and reservoirs and pushed uphill by 1 pump facility; that storage is the buffer that keeps taps running for a few hours after a pump or main fails.

What this means in an outage. Surface water needs a treatment plant running around the clock, so a plant shutdown, a raw-water pump failure or a long power cut at the plant can lower pressure across the whole service area, not just on one street. Boil water notices are more likely to be citywide after that kind of failure than after a single main break.

Why the water goes out in Buffalo

Water outages are local, so the likely cause depends on weather, pipe age and the grid. For Buffalo, these stand out.

• Freezing weather. Buffalo sees about 123 days a year with a low at or below 32°F, and 39 days at or below 20°F. The coldest morning in the 2015 through 2025 record came on February 16, 2015. The longest stretch with highs that never rose above freezing ran 26 days, ending March 2, 2015. Frost pushes into shallow service lines first. Mains follow when the ground heaves and thaws, which is why break counts climb a day or two after the temperature swings.
• Older neighborhoods and pipe. 85.4% of occupied homes in Buffalo were built before 1970, against 35.5% nationally. Streets of that age tend to sit on cast iron and early steel mains that are near or past their design life, which is where most breaks start.
• Flooding and heavy rain. NOAA logged 76 flood, flash flood and heavy rain reports in Erie County from 2015 through 2026. Floodwater can undercut pipe crossings, swamp pump stations and overload treatment plants, and a notice to boil water often follows when it enters the system.
• Storm-driven power loss. Thunderstorm wind, hail and tornado reports in Erie County number 223 since 2015. Pump stations and treatment plants that depend on National Grid run on the electric grid, so a storm that downs power lines can lower water pressure even when no pipe is damaged.
• Damage from other crews. Water mains share the ground with gas, power and telecom lines, and a strike by any contractor can dry up a block in seconds.
• Planned shutoffs and a problem at one address. Valve replacements and new connections are announced ahead, often with door hangers. If neighbors have water, check your own shutoff valve, meter and pressure regulator before calling.

Freeze, heat and rain: the Buffalo weather record

Main break season in Buffalo runs from late fall into early spring, with the coldest stretch around December through February.

These counts come from a gridded reanalysis, which smooths out single-day extremes and can differ by a few degrees from an airport thermometer. Use them to compare seasons and years, not as official station records.

Buffalo boil water notices and EPA compliance record

EPA lists no health-based violations for Buffalo Water Authority since 2015. It also lists 4 monitoring or reporting entries that are about paperwork rather than water quality, such as a missed sample or a late report.

Most recent entries, all monitoring or reporting:

• October 2024: A lead and copper violation It is marked resolved.
• July 2024: A missed or late monitoring or reporting requirement (lead and copper) It is marked resolved.

A boil water notice in Buffalo is a separate thing from a violation. Buffalo Water issues one when pressure falls low enough for contamination to enter the pipes, after a main break is repaired, or when a routine test comes back positive. The New York State Department of Health and county health departments oversees the process, and the notice stays until clean samples come back, usually a day or two after pressure returns.

Lead, older pipes and water quality in Buffalo

The most recent 90th-percentile lead result filed for Buffalo Water Authority is 4 ppb (2025). The federal action level is 15 ppb, so that result is comfortably below it.

The age of the housing matters more than the utility's test average: 85.4% of occupied homes in Buffalo predate 1970 and 1986 was the year lead pipe and solder were banned. Flush the cold tap after an outage and ask Buffalo Water whether your service line is on its lead inventory.

Restoration times for water outages in Buffalo

A crew that arrives at an ordinary main break in Buffalo usually needs 4 to 8 hours to isolate the pipe, dig, repair, flush and restore pressure. Large transmission mains, deep pipes and breaks under busy streets can take a day or more. With 276,000 people on the system, a break on a main that feeds a whole district can leave thousands of homes dry at once, and crews may close valves several blocks away to isolate it.

Buffalo Water will post an estimated restoration time for a break that affects many customers; ask for the repair crew's estimate when you call.

How much water to keep on hand in Buffalo

The average household in Buffalo has about 2.3 people, so FEMA's minimum of one gallon per person per day comes to roughly 7 gallons for three days and 32 gallons for two weeks.

• 16.3% of residents report a disability (US 13.3%), so check on neighbors who rely on running water for medical equipment.
• 57% of households rent. Tell your landlord or property manager about a leak or outage right away, since the shutoff valve may be theirs.
• Your water heater tank holds 30 to 50 gallons of clean water. Turn off the power or gas to it first, then drain from the valve at the bottom.
• If a planned shutoff or storm is coming, fill the tub and some buckets for flushing toilets and washing; keep drinking water in clean sealed containers.
