How Boston’s snow farms and high-capacity melters are clearing streets after February blizzards

A winter workload measured in truckloads

Boston’s recent run of heavy snow has put unusual pressure on the city’s snow-removal system, prompting an intense, days-long effort to move accumulated snow off neighborhood streets and into designated “snow farms” across the city. By the afternoon of Friday, February 27, municipal crews had transported 3,587 truckloads—about 59,344 cubic yards—into the snow-farm network for storage and melting.

The city has relied on snow farms for more than a decade as a way to manage limited curbside space and keep streets passable during large storms. The approach expanded significantly during the severe winter of 2015, when Boston recorded 110 inches of snowfall and some stored piles persisted into mid-summer.

What a snow farm is—and how it works

Snow farms are designated sites—spread around Boston to reduce hauling distances—where snow is dumped, stacked, and either allowed to melt gradually or processed using mechanical melting equipment. This winter, the city has operated a network that recently included 14 sites, then declined to 13 active locations as conditions and capacity shifted.

At some sites, contractors have deployed diesel-powered snow melters—industrial machines that use heated water and high throughput systems to liquefy snow quickly. One melter operating near the former West Roxbury High School was described as capable of consuming up to 135 tons of snow per hour. The work relies on heavy equipment, including front-end loaders, backhoes, and 10-wheel dump trucks, operating in repetitive cycles to feed snow into the melter and keep haul routes moving.

Why Boston isn’t dumping snow into the harbor

Boston has not sought authorization to dispose of snow in Boston Harbor during the recent storms. The city has instead used snow farms to handle the volume, even as seasonal snowfall totals rose above 60 inches for the first time since 2015.

State rules prohibit dumping snow into Boston Harbor, a practice barred in 1997, while still allowing for emergency exceptions. City officials have indicated that a larger storm of similar magnitude could force consideration of emergency options, but the current system is intended to avoid that outcome.

Where the meltwater goes—and what gets monitored

At snow-farm sites using melters, the resulting water is directed into storm drains. Those drains feed into a broader drainage system that can, during periods of high flow, overflow into rivers and streams. City water and sewer personnel have conducted site visits to confirm that meltwater is routed properly and that erosion-control measures are in place.

• Snow is transported to dispersed snow farms to shorten neighborhood hauling routes.
• Mechanical melters can rapidly reduce piles that would otherwise linger into spring.
• Operations are continuous and fuel-intensive, requiring on-site diesel resupply.

During the 2015 winter, some of Boston’s largest stored snow piles lasted for months, underscoring why rapid-melt capacity is now a central part of the city’s snow response.

As temperatures and sunlight increase, officials expect natural melting to assist the effort, though the final remnants of this season’s accumulated snow may still take weeks to fully disappear.
