Namibia’s capital, Windhoek, has had difficulty providing its population with drinkable water due to an acute water shortageTo combat its water problem, Windhoek is treating sewage water and transforming it into clean, drinkable waterAfter the water is treated, it is directly injected into the city’s water distribution system for usage and consumption.
Namibia is one of the driest nations in Africa. The amount of water that evaporates is 83%, and the country does not have a river that passes through it. To combat this problem, the Goreangab Water Treatment Plant in Windhoek transforms sewage into drinkable water for its residents.
Namibia joins Singapore as the only two countries that utilize their waste water to create drinking water, which is pumped back into the home’s water supply system.
Goreangab Wastewater Treatment Plants’ Process Engineer, Justina Haihambo, explained that: Consuming drinking water from a wastewater recycling plant is an idea that still sometimes bothers some people, even in Windhoek where the solution is proven and very reliable. It’s important to know that everything is done biologically: bacteria help digest waste and extract it from the water, mimicking what happens in nature, but much faster
This system is anticipated to continue providing clean drinking water for several decades because the new plant is even more efficient regarding the quantity and quality of drinking water produced. Goreangab’s Process Engineer further added that in the past 50 years, no significant health incidents associated with the consumption of this water had been discovered.
The trial inspired 500 people’s wastewater to be collected in vacuum sewers and processed to get rid of all pathogens. The company is also considering building a second facility to turn wastewater into drinking water.
