Bolsover Water Hardness & Quality Report (2026)

Severn Trent Water serves Bolsover, Derbyshire, drawing from a mix of sources. These include groundwater from aquifers like the Sherwood Sandstone Group, surface water from the River Trent and its tributaries, and reservoirs such as Carsington Water. Water undergoes comprehensive treatment, including filtration, disinfection, and fluoridation, at facilities like those in the Derwent Valley before reaching residents.

The region's water originates in the Trent catchment, flowing through Triassic sandstones and mudstones. Key aquifers are found in the Permo-Triassic strata beneath Derbyshire, featuring rock formations like the Mercia Mudstone. As water moves through the rock's fissures and fractures, it dissolves minerals, resulting in a water supply that is naturally moderately hard to hard. This prolonged interaction within the lowland aquifer system contributes to elevated dissolved solids.

Homeowners in Bolsover likely notice limescale buildup in appliances like kettles, boilers, and showerheads, which can decrease their efficiency and shorten their lifespan. Washing machines, dishwashers, and hot water systems are particularly susceptible, as scale acts as an insulator on heating elements. Regular descaling with vinegar can help, as can installing magnetic conditioners or using filtered water for drinks. For persistent scaling issues and to protect plumbing, installing a water softener is often recommended to improve soap lathering and appliance longevity. Severn Trent consistently receives high ratings from the Drinking Water Inspectorate.
