Water Quality Test in our Hospital
In February 2010 we, the technicians of CCBRT-Hospital, made a water quality test.
Several different waters were collected and the conductivity were measured.
The measurement results are mentioned in µS/cm.
The conductivity is the benchmark for the water quality for technical applications.
According international standards the required value should be less than 30 µS/cm for sterilizers and less than 10 µS/cm for car batteries.
Results
| DAWASCO (local water provider, tap water) | 249 |
| Rain water (from CCBRT rain water tank) | 130 |
| Well water (from CCBRT well water tank) | 1616 |
| Rain water | 14 |
Commercial distilled water
| Distilled water I (Duma) | 189 |
| Distilled water II (Msasani) | 103 |
| Distilled water III (unknown) | 185 |
Commercial drinking water
| Cool Blue | 62 |
| Kilimanjaro | 258 |
| Uhai | 226 |

1. No commercial distilled water is distilled water. They are just normal tap water. Even'Cool Blue' drinking water is better than the commercial 'distilled' ones.
2. Rain water is by far the best water for technical applications.
3. CCBRT rain water tank contains a mixture of tap water and rain water.
4. Rain water does not reach the requirements for car batteries, but is close to and anyway
much better than the 'distilled' water which is sold in car accessories shops.
Conclusion
Only (filtered) rain water should be used for the
maintenance of car batteries. Only (filtered) rain water can be used for running
sterilizers. The rain water tanks at CCBRT-Hospital may not filled
up with tap water. In order to use rain water all year round, the
rain water tanks at CCBRT-Hospital shouldbe enlarged.
