Oakwood Water Hardness & Quality Report (2026)

Oakwood's water comes to your tap courtesy of Severn Trent Water, a major utility serving the West Midlands and East Midlands. The supply is drawn from a mix of sources, including surface water and groundwater, before being processed at the Derby Treatment Works. From there, it travels through the network to reach homes and businesses in Derbyshire and surrounding areas. The Severn Trent Water watershed includes the Derwent Valley and the Pennine uplands. This region's geology plays a significant role in shaping the water's character.

Geologically, the area is defined by Carboniferous Limestone and Millstone Grit formations from the Carboniferous period. As rainwater filters through these limestone aquifers, it picks up naturally occurring calcium and magnesium ions. This geological process is what gives the water its distinctly hard, moderately mineralised profile, a common trait for supplies originating in these Peak District watersheds.

This moderately hard water means you might notice limescale buildup in your appliances, like kettles and showerheads, over time. You'll also find that soap doesn't lather quite as easily, and scum can appear in the bath. To combat this, regular descaling with household solutions like vinegar can help. For persistent issues or to prolong the life of your appliances, many households find installing a water softener to be a worthwhile investment. Severn Trent Water confirms that quality reports, including details on PFAS and lead levels, are available on their website.
