Grit bin

Grit bins are street containers used in places with freezing winters. They hold a mix of salt and grit that is spread on roads and pavements when there is snow or ice. Salt lowers the freezing point of water so ice melts, while the grit improves traction for cars and people. During severe weather, busy roads may be treated several times a day.

Anyone can use a grit bin to clear a public path, but they aren’t meant for private use. A shovel is usually kept with the bin to spread a thin layer of grit over the surface. Some bins have a small compartment to store tools, and many have a top hatch for easy filling.

If the lid is left open and rain gets in, the salt can dissolve and become less effective. Bins can be damaged by vandalism, and plastic bins can be easier to steal or tip over than heavier materials.

In the UK, local councils are usually responsible for maintaining and refilling grit bins and spreading salt on the roads. Grit bins were once made from concrete, wood, or stone, but many are now plastic. In Norway, some bins are built large enough to hold about 500 kg of grit to ensure a steady supply.

Some places store mainly sand or sand-salt mixes instead of salt alone.
