The Namibia Water Corporation (NamWater) has responded to concerns from Katima Mulilo residents about brownish discolouration in their tap water.
NamWater spokesperson Lot Ndamanomhata said the water is microbiologically safe to drink, despite its colour.
He explained that the Katima Water Treatment Plant is operating beyond its design capacity during peak demand, putting extra strain on the plant’s sand filtration system.
“This strain has affected the water’s appearance,” he said.
Ndamanomhata added that seasonal increases in the Zambezi River’s flow have raised iron and manganese levels in the raw water.
He said that while this affects the water’s look, it still meets health and safety standards.
“Laboratory results have consistently confirmed that the water is microbiologically safe for human consumption,” he said.
In response to complaints, NamWater has taken several steps.
These include replacing the filter sand, using more disinfectants, and increasing how often they backwash the filters.
We have also advised large water users like Meatco to use interim filtration measures to manage turbidity while we plan long-term upgrades.
The tender for filter rehabilitation and sand replacement closed on 8 May 2025. Procurement and evaluation are currently underway.
Ndamanomhata said NamWater is committed to restoring water quality and thanked the Katima Mulilo community for their patience.
