Cockington Water Hardness & Quality Report (2026)

South West Water serves the village of Cockington, located near Torquay in Devon, UK. The primary water sources are moorland reservoirs, including Tottiford Reservoir and Avon Reservoir, situated within the Dartmoor area. Water is drawn from these surface sources and then treated at facilities such as the Tottiford Water Treatment Works before being distributed throughout the South Hams and Torbay supply zones. This region's water supply largely depends on upland catchments.

The Dartmoor watershed is characterized by its granite uplands, covered by peat bogs and thin soils, which contribute to a very soft water profile. The Carboniferous granite bedrock weathers very slowly, releasing minimal minerals into the water. Additionally, acidic runoff from the moorlands and filtration through peat further reduce the concentration of dissolved solids, resulting in characteristically soft surface water low in calcium and magnesium. This geological makeup contrasts sharply with the harder groundwater sources found in areas like East Devon boreholes.

Because the water is very soft, you'll notice limescale buildup is not a significant issue for appliances like boilers, kettles, and washing machines, leading to less maintenance. Soap lathers easily, though a slight residue might sometimes appear on fixtures. Homeowners typically won't need a water softener. Instead, occasional cleaning of taps and showerheads with vinegar can address any minor staining that might arise from natural moorland organics. South West Water ensures compliance with UK drinking water standards, with pH levels generally ranging from 7.0 to 8.0 for these surface supplies. Extensive pipe replacement programs help maintain low lead and copper levels, and recent testing shows no notable PFAS detections in the supply zones.
