Hard water carries a lot of dissolved calcium and magnesium. It is common in borehole water in many parts of Kenya. It is not usually a health risk, but it costs money through scale, wasted soap and damaged appliances. Here is how to recognise it and fix it, with equipment on Buy More Mall from Herritech Ventures (H-TECH).




The signs above are a good clue. For a number, a water laboratory measures hardness (usually as mg/L of calcium carbonate). A TDS meter gives a rough idea of total minerals but does not measure hardness itself; see TDS in Drinking Water.
Generally yes: the calcium and magnesium in hard water are not harmful to drink. The problems are mainly scale, taste and soap use. Many people still prefer the taste of RO-treated water for drinking.
Some people find their skin feels dry and their hair dull or rough with hard water, because soap does not rinse off well and leaves a film. Softened water rinses more cleanly.
| Solution | What it does | Best for |
|---|---|---|
| Water softener | Swaps calcium and magnesium for sodium (ion exchange), stopping scale | Whole house, hotels, laundries, boilers |
| Reverse osmosis | Removes most dissolved minerals, including hardness | Drinking water; protecting equipment |
| Softener before RO | Protects the RO membrane from scaling | Water businesses with hard borehole water |

Quick fix for scale: descale kettles and shower heads by soaking them in vinegar, then rinse well. A softener stops the scale forming in the first place.
