What Makes Heywood's Water Unique?

Local geology and source profile

Source: MixedTDS: 262.3 mg/LpH: 7.6

Residents of Heywood receive their water from United Utilities, drawing primarily from Watergrove Reservoir. This reservoir is situated above Whitworth, and the supply network extends across the West Pennine Moors. The water undergoes treatment before distribution to homes and businesses.

The water's journey begins in a soft Carboniferous Millstone Grit moorland catchment. This geological makeup is the reason the water is characterized as moderately soft, registering at 8.7°Clark. The rocks in this region don't readily dissolve minerals like calcium and magnesium into the water.

Homeowners may notice that this moderately soft water is generally kind to appliances and plumbing, leading to less scale buildup compared to harder water supplies. You might find you use slightly less soap and detergent for washing and cleaning. If you're accustomed to very hard water, the difference in lathering may be noticeable, but it doesn't pose any widespread issues for everyday use.
