Cardiff Plumbing: The Numbers
Water Hardness
Cardiff has soft to moderately soft water — supplied from the Elan Valley reservoirs in Mid-Wales.
| Metric | Cardiff Value |
|---|---|
| Average hardness | 30–70 mg/L CaCO3 |
| Classification | Soft to Moderately Soft |
| Water supplier | Dŵr Cymru / Welsh Water |
| Source | Elan Valley reservoirs (Mid-Wales) |
| Corrosion risk | Moderate — soft water corrodes old pipes |
Cardiff's water travels from the Elan Valley reservoirs through a Victorian aqueduct system. The soft water is excellent for drinking but can corrode old pipework, particularly cast iron and copper.
City Centre (CF10): 30–50 mg/L — soft Roath (CF24): 35–55 mg/L — soft Cathays (CF24): 40–60 mg/L — soft Penylan (CF23): 45–65 mg/L — soft to moderately soft Cardiff Bay (CF10): 35–55 mg/L — soft

| Butetown | Medium | Mixed drainage systems |
| Tiger Bay | Medium | Historic dock drainage |
| Penarth | Medium | Coastal drainage, tidal influence |
| Barry | Medium | Mixed drainage systems |
Waterfront Drainage Issues

|---|---|---|
| Tidal backflow | Bristol Channel tidal influence | £180–£450 (non-return valve installation) |
| Surface water flooding | Heavy rain overwhelming drainage | £160–£440 (drainage improvements) |
| Combined sewer overflow | Foul and surface water mixing | £140–£370 (survey and separation) |
| Root ingress | Victorian clay drains | £130–£310 (root removal and repair) |
