City of Windhoek (CoW) officials have attributed discoloration of drinkable water to some elevated levels of iron and manganese in borehole water which they have been using for the Emergency Water Supply project.
Namibia, specifically capital of Windhoek, has been experiencing low levels of water due to the drought and the city’s authorities were forced to look at alternative water resources to sustain the livelihood of the city and all its inhabitants.
Public Relations Officer at the City of Windhoek (CoW), Lydia Amutenya said in a statement on Wednesday that the main aim of the Emergency Water Supply project was to find enough water that could sustain 60 percent of the demand of the city in order to keep the city functional.
According to Amutenya abstraction from the CoW aquifer has in the past proven that there are some high levels of especially iron and manganese in borehole water which tend to discolor the product water and items it may come in contact with.
“Although water production has reduced, reservoirs and the water reticulation network is already saturated with elevated levels of these constituents and it may take some time before the system may be flushed clean,” she said.
Meanwhile, the national water supplier, NamWater said they have also experienced increased iron and manganese levels in water as a result of recent inflow into the dams.
“The problem was solved and we expect water discolouration to reduce to normal, but this can occur from time to time during the testing period which is expected to run until October,” NamWater said. Enditem
