Kirkby in Ashfield Water Hardness & Quality Report (2026)

Residents of Kirkby in Ashfield, Nottinghamshire, receive their water supply from Severn Trent Water. The utility draws from a mix of sources, including groundwater aquifers like the Sherwood Sandstone and surface water from the River Trent. These waters are treated at facilities such as the Attenborough and Derwent treatment works before distribution. Severn Trent Water serves millions across the East Midlands, with the watershed for Kirkby in Ashfield encompassing the Trent Valley and its adjacent uplands. The water's journey begins in these diverse geological settings, ultimately providing the mains water for the community.

The geology beneath Kirkby in Ashfield plays a significant role in the water's character. The region sits atop Triassic sandstones and mudstones, part of the Mercian Mudstone Group and Sherwood Sandstone Group aquifers. Additionally, the presence of carbonate-rich Permian limestones, including the Magnesian Limestone, means that as groundwater percolates through these strata, it dissolves minerals like calcium and magnesium. This natural mineralisation, particularly from the limestone-dominated formations, results in a water supply that is typically moderately hard to hard, even with some dilution from river sources.

This moderately hard water can lead to the formation of limescale, a common nuisance that coats the inside of kettles, boilers, and showerheads. This buildup not only reduces the efficiency of heating systems and appliances like washing machines and dishwashers but can also shorten their lifespan. You might notice spotting on fixtures and experience blockages over time. To combat this, regular descaling with household vinegar is advised, and fitting limescale filters on taps can help. For those looking to prevent long-term damage and improve how soaps lather, installing a whole-house water softener is a worthwhile consideration. Severn Trent Water provides detailed quality reports online, confirming compliance with drinking water standards and management of minerals like iron and manganese from groundwater sources.
