Bury Water Hardness & Quality Report (2026)

United Utilities supplies Bury, drawing water primarily from upland reservoirs in the Pennines. These sources, part of the Irwell and Roch river catchments, feed into treatment plants before reaching roughly 7 million customers across the North West. Secondary sources include boreholes that tap into mineralised Permo-Triassic sandstone aquifers in the southern region, with the waters then blended to meet demand. These upland catchments are part of the Carboniferous Millstone Grit and Millstone Edge Grit formations.

The geology feeding Bury's supply is predominantly Carboniferous Millstone Grit and Millstone Edge Grit formations in the Pennines, which naturally yield soft water. However, boreholes in the southern area access more mineralised Permo-Triassic sandstone aquifers. The blending of soft surface water with this harder groundwater results in a supply that is generally soft to moderately mineralised, though it can vary seasonally depending on demand and source contributions.

Most households won't notice significant scale buildup in kettles or appliances with this water, and soap lathers well, making a water softener generally optional. Still, some residents in areas receiving a higher proportion of groundwater might observe minor scale in high-temperature appliances like boilers and dishwashers. United Utilities treats all its water to meet stringent UK Drinking Water Standards, employing filtration, UV, and chlorine disinfection for surface water, alongside appropriate treatment for groundwater before blending.
