What Makes Walsall's Water Unique?

Local geology and source profile

Source: MixedTDS: 369.5 mg/LpH: 8

Walsall is supplied by South Staffs Water, a major utility serving the West Midlands. The company draws water from a combination of surface sources like rivers and reservoirs, alongside groundwater from local aquifers. These raw water supplies undergo treatment at South Staffs Water's facilities before being distributed to homes and businesses throughout Walsall and neighboring communities.

The Walsall water supply originates within the West Midlands watershed, an area defined by Carboniferous and Triassic geological formations. These rocks include sandstones, mudstones, and significant limestone deposits. As rainwater filters down through these layers, it picks up naturally occurring minerals, primarily calcium and magnesium. This process is what gives the local water its characteristically hard quality, a common trait across the West Midlands region due to its underlying geology.

This hard water can lead to limescale buildup in household appliances like kettles, water heaters, and dishwashers, potentially shortening their lifespan and reducing efficiency. You might also find that soaps and detergents don't lather as readily. To combat these issues, South Staffs Water suggests that residents in hard water areas consider installing a water softener. This can help protect plumbing and appliances from scale, ultimately saving on maintenance and replacement costs.

Geology & Source: Carboniferous and Triassic sandstones, mudstones, limestone; dissolution of calcium and magnesium minerals causes hardness
