Solihull Water Hardness & Quality Report (2026)

Solihull receives its water supply from Severn Trent Water, a major utility serving the West Midlands. Their system is a mix, drawing water from both surface sources like rivers and reservoirs, and underground aquifers. Severn Trent Water manages numerous treatment facilities that purify this water before it reaches the taps of over 4 million customers across the region.

The geology beneath Solihull plays a significant role in the water's character. The area is situated atop Triassic-age Mercia Mudstone and Sherwood Sandstone formations. As water filters through these rock layers, it dissolves minerals, primarily calcium and magnesium compounds. This geological makeup is why the West Midlands region, like much of central and southern England, is known for having hard water.

Living with hard water means you'll likely notice scale buildup in appliances such as kettles and boilers, and on bathroom fixtures like shower screens. To combat these mineral deposits and help appliances run more efficiently, many homeowners in the region opt for water softeners. Rest assured, Severn Trent Water ensures all its supplied water meets strict UK drinking water standards, and they provide detailed quality reports for customers.
