Pollution contributes to water scarcity

WINDHOEK, 22 FEB (NAMPA) – Water pollution and evaporation are some of the biggest threats to the availability and provision of water in Namibia.
Blue-green algae from phosphate, nitrates and other elements found in washing powders and bars of soap are contributing to the scarcity of water.
This was said by Koos Theron, a manager in the Khomas Water Supply division at the Namibia Water Corporation (NamWater) during a media briefing on the water scarcity crisis in the country on Friday.
“Blue and green algae is a big threat. It is in increasing threat to the quality of the water in the Swakoppoort Dam. It could possibly threaten the closure of that dam if the spread of bacteria and poison continues,” said Theron.
Blue and green algae or Cyanobacteria is the most genetically diverse algae and occupies freshwater, marine, and terrestrial ecosystems.
It is found in places such as hot springs, salt works and water dams.
He added that due to the hot climatic conditions in Namibia evaporation is also one of the biggest threats to the availability of water.
“Because of this, the quality of our water has depreciated and we have been struggling to maintain the quality of the water as should be,” he said.
Theron added that a serious plan is needed and more awareness is vital to educate the masses on the consequences of their actions.
“We might lose 63 per cent of our water due to this. Currently we lost about 2,3 millimetres of water due to evaporation and pollution is indeed a big threat,” he noted.
Theron added that the water utility has resorted to utilising six Solar Bees bought in 2014 for N.dollars 6 million.
“They float on the water and circulate the water to hinder the expansion of algae by causing pressure on the algae to burst open and die. They have their own lights and are very efficient,” he said.
