This simplified model explains exactly how to calculate your water bill based on your consumption and as per the City’s four-block tariff system. We are currently in Category C of our water management system since May this year.
‼️NB: The tariff for each block may change every year depending on the water price increase as passed on from NamWater.
‼️NB: The City of Windhoek does not add a markup to the first six cubic meters (6m³) consumed by residents, meaning it is charged at the same price bought from NamWater. Such price per cubic meter is 24.41
How to calculate your water under category C:
📌Tariff block 1: Your consumption up to 6m³ per month and it is calculated as follows: N$24.41 x 6=N$146.46 your water bill.
📌Tariff block 2: Your consumption is up to 25m³ per month. We charge the first 6m³ at 24.41 and the remaining 19m³ is charged at 37.83. The consumption is calculated as follows: 6m³ x N$24.41 +19m³ x N$37.83 = N$865.23.
📌Tariff block 3: Your consumption is above 25m³ and up to 40m³ per month. We will charge you the first 6m³ at N$24.41, 19m³ at N$37.83 and the remainder at N$75.67 per m³.
📌Tariff block 4: Your usage is above 40m³. We will charge you the first 6m³ at N$24.41, 19m³ at N$37.83, 17m³ at N$75.67 and the reminder at N$151.32 per m³.
📌So the higher your monthly water consumption, the higher you pay per cubic meter.
NB: 1 cubic meter (m³) = 1000 Liters
Save water and pay less
