South West Water
Water in Plymouth
- Plymouth has soft water supplied by South West Water, drawn largely from Dartmoor.
- Dartmoor granite contributes very little mineral content, so the water is genuinely soft and limescale is not a local problem.
- Plymouth's supply has run from Dartmoor since Drake's Leat was constructed in 1591, one of the oldest municipal water schemes in the country.
- Softeners are essentially never justified in Plymouth, and filtration demand is about taste and chlorine.
- Soft, slightly acidic moorland water is more plumbosolvent, so drinking water filtration in older properties has a genuine rationale unrelated to hardness.
You have soft water — there is no limescale problem to fix.
A water softener would be money spent on a problem you do not have, and anyone trying to sell you one here is worth questioning. If you want to improve your water it will be about taste, chlorine or older pipework, not hardness. Soft water is also slightly more inclined to dissolve metals from old plumbing, which is a different reason to filter drinking water.
