Residents of Tsumeb are advised to continue boiling water for consumption.
This was said by the town's chief executive officer, Victoria Kapenda.
Since last year, Tsumeb residents have been having serious water issues as a result of underground water contamination.
Dundee Precious Metals, which operates a copper smelting plant in the town, also confirmed that the water had high microbiological traces.
The process of shock chlorination, or the disinfection of water sources, led to an improvement in the water quality compared to last year.
However, residents are advised to continue boiling water that is to be used for consumption.
"There are problems that are facing local authorities, and we are not an exception, but as the leadership, we are committed to ensuring that our communities are safe."
For a long-term solution, the municipality is looking to construct a water purification plant.
The Tupperware Reservoir was rehabilitated, and the lining is done for about N$4.7 million, though the membrane filtration plant is still to be constructed and the network needs to be replaced.
"Pipes were installed some years ago, about 60 years ago, and everything is honestly not in good condition, so we still have to do it."
The reservoiris already functional.
