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 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. Every shower, every sink, every appliance.
BathSoft
A bathroom filter has to do three things at once: treat the water, fit the space, not announce itself.
Drinking water systems
The one tap where chemistry beats every other concern. RO or UF + UV is a 10-minute test, not a sales decision.
Birat Medical College
Campus water treatment + drinking-water RO across teaching and residential blocks.
Service is the system
Most water companies show up when something breaks. We show up every month.
Automated.
Backwash, regeneration, flush — the system handles routine cycles on a schedule. No valves to turn.
Verified by an engineer.
Monthly site visit. Pressure check, media inspection, hardness/iron spot test, written report.
Owned by us.
If something needs replacement or recalibration, we do it. No customer chasing parts.
The discipline that decides year four.
