Commercial water filtration in Cardiff
Water treatment for Cardiff businesses — cafés, restaurants, offices, salons and gyms. Cardiff has soft water, which decides whether your priority is protecting equipment or improving taste.
Soft
Dŵr Cymru Welsh Water
Water in Cardiff
- Cardiff is supplied by Dŵr Cymru Welsh Water, whose supply across Wales ranges from very soft upland water to moderately hard, and Cardiff sits nearer the softer end.
- Welsh Water is a not-for-profit company owned by Glas Cymru, a structure unique among UK water companies, and it publishes water quality data for supply zones across its area.
- South Wales draws on a mixture of upland reservoir and river sources, so hardness is more variable here than in the softest parts of north and west Wales.
- Softeners are rarely justified in Cardiff, and filtration demand is driven by taste and chlorine.
- Cardiff's growing food and drink sector accounts for most local commercial filtration work.
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.
