Researchers at the ongoing Bulawayo Economic Development Conference (BEDCOM) have proposed practical and sustainable solutions to help the city tackle its persistent water shortages.

Kelvin Mutseta, an academic from the Namibia University of Science and Technology, recommended the adoption of smart water management technologies. He said these systems can detect leaks in real time, reduce water loss, and improve the overall quality and efficiency of water supply.

“These technologies allow us to pinpoint and address leaks immediately, minimizing wastage and ensuring that precious water resources are utilized effectively,” Mutseta explained.

C. Mpala from Lupane State University proposed vermifiltration, a low-cost method that uses earthworms to clean septic sewage water. He said the treated water can be safely reused for irrigation and landscaping.

“Vermifiltration offers a low-cost, environmentally friendly approach to wastewater management, allowing us to reuse treated water and reduce the strain on our limited water resources,” Mpala stated.

University of Zimbabwe biochemist Nduduzo Mbele introduced phytoremediation as a solution to industrial water pollution. He recommended using Kariba weed (Salvinia molesta) to absorb heavy metals, supported by bio platforms to prevent overgrowth and blockages. He said the method could help cut water treatment costs.

“Phytoremediation offers a natural and sustainable way to clean industrial wastewater, reducing the need for costly chemical treatments,” Mbele highlighted. “By utilizing Kariba weed, we can effectively remove pollutants and improve the quality of our water sources.”
