Nepal
Uniwater in Kathmandu.
Mixed jar, municipal, and borewell supply. Drinking-water RO at the kitchen pays back inside two years.
The water
What Kathmandu water actually looks like.
Lalitpur, Bhaktapur, and the Kathmandu core each run on distinct municipal profiles. Borewell augmentation is common at most premium addresses. Hardness moderate to high; iron present in some blocks. A free 10-minute test at survey decides RO vs UF + UV at the kitchen tap.

Water by locality
What the water reads, area by area in Kathmandu.
Indicative ranges only. Kolkata figures come from our field experience, other cities from published regional groundwater studies. Groundwater varies borehole to borehole, so the number that sizes your system is the one our engineer measures at your address, not the band below.
| Locality | Iron | Hardness | TDS | Dominant issue | Typical system |
|---|---|---|---|---|---|
| Lalitpur | 0.3–3 ppm | 60–280 ppm | 150–500 ppm | Iron above the aesthetic limit (staining, taste); hardness moderate. | Iron removal where needed; kitchen RO or UF + UV on a TDS test. |
| Bhaktapur | 0.3–3 ppm | 60–260 ppm | 150–500 ppm | Iron and ammonia in urban boreholes; hardness moderate. | Iron pre-treatment + drinking-water RO at the kitchen. |
| Maharajgunj | 0.3–2.5 ppm | 50–250 ppm | 150–450 ppm | Localised iron staining; hardness within limit. | HomeSoft softening with an iron stage; kitchen RO or UF + UV. |
| Patan | 0.3–3 ppm | 60–280 ppm | 150–500 ppm | Iron and aesthetic issues; hardness generally within limit. | Iron removal + drinking-water system sized by a TDS test. |

Systems we install here
What goes into a Kathmandu home, typically.
The right answer comes from the survey, not the catalogue. These are the four systems most commonly specified in Kathmandu, in order of how often they appear on installation invoices.
HomeSoft
One softened, filtered supply for the whole house, from the showers to the washing machine.
BathSoft
A bathroom filter has to treat the water, fit the space and stay out of sight.
Drinking water systems
At the drinking tap, chemistry matters more than anything else. Whether you need RO or UF + UV comes from a 10-minute test, not a sales pitch.
Birat Medical College
Campus water treatment + drinking-water RO across teaching and residential blocks.
Service
Most water companies come when something breaks. We come every month.
Automated.
Backwash, regeneration and flush run on a timer. Nobody has to turn a valve.
Verified by an engineer.
A site visit every month: pressure check, media inspection, hardness and iron spot test, and a written report.
Owned by us.
If a part needs replacing or recalibrating, we do it. You don’t chase anyone for parts.
Service is what keeps a system working in year four.
