Rongai Borehole Water Quality: What the TDS Numbers Mean for Your Family
01, Sep 2026
Many Westlands and Kilimani apartments have hard water, which leaves white limescale on kettles, taps, and appliances, and a film on glasses. Hard water is caused by dissolved minerals, and Reverse Osmosis removes them, protecting both your appliances and your drinking water.
Hard water is water with a high content of dissolved minerals, mainly calcium and magnesium. It is not dirty in the visible sense, and it is not unsafe to touch, but those dissolved minerals cause the effects residents notice. When hard water is heated or left to dry, the minerals are left behind as the white, chalky deposit called limescale. In an apartment relying on borehole or mixed supply, this mineral load can be significant.
Limescale is not only unsightly. Inside a water heater or a kettle, scale acts as insulation, making the appliance work harder and wear out faster, which quietly raises electricity use and replacement costs. For drinking, high dissolved-mineral water carries the same sustained load on the body that any high-TDS water does. So hard water is both a household-cost problem and a water-quality one.
Reverse Osmosis removes the dissolved minerals that cause hardness, along with the other contaminants in the supply. This is why apartment residents in these neighbourhoods are increasingly choosing RO for their drinking and cooking water: it ends the limescale and the film, and it protects both the appliances and the people. Because most apartment dwellers cannot alter building plumbing, the portable iClear Desktop is the popular choice here, delivering full RO purification with no installation. Where under-sink installation is possible, the iClear Standard covers the whole kitchen.
Hard water in a Westlands or Kilimani apartment is a dissolved-mineral problem showing up as limescale and film. Reverse Osmosis removes the minerals at the source of your drinking water, which is why the switch has become common in exactly these high-density, apartment-heavy areas.
Q: Why do Westlands and Kilimani apartments have hard water?
A: Hard water comes from dissolved minerals, mainly calcium and magnesium, in the supply. Apartments drawing on borehole or mixed supply in these areas often carry a high mineral load, which shows up as limescale and film.
Q: Does Reverse Osmosis remove hard water minerals?
A: Yes. RO removes the dissolved calcium and magnesium that cause hardness, along with other contaminants, cutting TDS dramatically. This ends the limescale and film on your drinking and cooking water and protects appliances.
Q: Can I fix hard water in an apartment I rent?
A: Yes, for your drinking and cooking water. A portable RO purifier like the iClear Desktop needs no plumbing and removes the dissolved minerals, so renters can solve hard water at the tap they drink from without altering the building.
