KUKL Kathmandu Water Bill Calculation: Metered Units, Pipe Size & 50% Sewerage
Kathmandu Upatyaka Khanepani Limited (KUKL) distributes municipal drinking water across Kathmandu, Lalitpur, and Bhaktapur. Billing depends on customer pipe connection diameter (typically half-inch for residences), recorded consumption liters, and a mandatory 50% sewerage maintenance levy.
- Standard residential half-inch (0.5 inch) pipe connection has a monthly minimum charge of NPR 100 for up to 10,000 liters.
- Consumption beyond 10,000 liters incurs a progressive tariff of NPR 32 per additional 1,000 liters (1 Unit).
- A mandatory Sewerage Service Charge equal to 50% of the net water charge is added to every customer bill.
- Unmetered flat connections pay fixed monthly rates based on pipe diameter.
Residential Metered Water Tariff Structure (0.5 Inch Pipe)
KUKL measures municipal water in units where 1 unit equals 1,000 liters (1 cubic meter):
| Monthly Water Consumption | Water Tariff (NPR) | Sewerage Charge (50%) | Total Monthly Bill (NPR) |
|---|---|---|---|
| Up to 10,000 Liters (10 Units) | NPR 100 (Minimum Base) | NPR 50.00 | NPR 150.00 |
| 15,000 Liters (15 Units) | NPR 260.00 | NPR 130.00 | NPR 390.00 |
| 20,000 Liters (20 Units) | NPR 420.00 | NPR 210.00 | NPR 630.00 |
| 30,000 Liters (30 Units) | NPR 740.00 | NPR 370.00 | NPR 1,110.00 |
Commercial and Larger Pipe Diameters
Commercial complexes, hotels, and hospitals utilizing 0.75-inch, 1.0-inch, or 2.0-inch main connections pay significantly higher minimum quotas and steeper volumetric energy charges reflecting intensive institutional demand.
