Aylestone Water Hardness & Quality Report (2026)

Severn Trent Water provides the water supply for Aylestone in Leicestershire, East Midlands, UK, serving Leicester city and surrounding areas. The water comes from a mix of sources. For surface water, it's drawn from the River Derwent and River Soar catchments. Groundwater is also a key component, sourced from Permo-Triassic sandstone aquifers and various local boreholes. Water undergoes treatment at facilities like the Derwent Valley Water Treatment Works near Derby and the Stanford Reservoir facility before reaching homes through an extensive network.

The region's geology plays a significant role in the water's character. It taps into the Mercian Supergroup mudstones and sandstones from the Triassic period, as well as Jurassic-era limestones such as the Lincolnshire Limestone Formation. These rock layers, particularly the limestones and dolomites within the Permo-Triassic Sandstone Aquifer, are rich in minerals. As rainwater filters through these formations, it dissolves calcium and magnesium, leading to groundwater that is characteristically hard.

Homeowners in Aylestone may notice the effects of this hard water, which can lead to limescale buildup in appliances like kettles, boilers, and washing machines. This buildup not only reduces efficiency and shortens the lifespan of these devices but also affects how well soap lathers. Regular descaling with household items like vinegar or citric acid can help manage the issue. For those in particularly hard water areas, installing a whole-house water softener is often recommended to combat scaling, improve soap performance, and protect your appliances.
