What Makes Oadby's Water Unique?

Local geology and source profile

Source: MixedTDS: 351 mg/LpH: 7.8

Severn Trent Water supplies Oadby in Leicestershire with mains water drawn from a mix of sources. This includes surface water from the Draycote Reservoir and the River Soar tributaries, as well as groundwater from boreholes tapping into local Triassic sandstone aquifers. Treatment occurs at facilities like the Cropston and Knighton plants, managing a supply that combines reservoir and river water with abstracted groundwater before it reaches homes in Oadby and the surrounding East Midlands region.

The water's journey begins in the Soar catchment, flowing through sedimentary rock layers like the Mercia Mudstone Group and Sherwood Sandstone Group formations. Jurassic limestones also play a role in shaping the groundwater chemistry. These geological formations, particularly the limestones and sandstones, are rich in calcium-bearing minerals. As rainwater percolates through these permeable layers, these minerals dissolve, giving the water its characteristic moderately hard to hard quality, a common trait in the East Midlands compared to softer supplies found in other parts of the UK.

Residents in Oadby may notice limescale buildup in appliances like kettles, boilers, and showerheads, which can reduce their efficiency and lead to higher energy bills. You might find that soap lathers less readily, requiring more detergent for cleaning tasks. To combat these effects and protect your plumbing and appliances, regular descaling with household solutions like vinegar can help. For a more comprehensive solution to prevent pipe clogging and extend the lifespan of washing machines and dishwashers, installing a whole-house water softener is often recommended in hard water areas.
