“But because of water-shedding, people are now using less and less water. Some are not even flushing when they are not doing what we call 'number two',” he added.
Bulawayo metropolitan province has just under a million citizens, who go for an average of three days a week without water.
So far, one of the city’s six water-supply dams has been decommissioned. The remaining five have an average water level of 37%.
Bulawayo mayor Solomon Mguni warned in a statement that if this season's rainfall was below average, another dam would be decommissioned in early 2020.
“As of November 2, dam levels stood at just below 37%, which may force us to decommission additional dams soon,” he said.
The “big flush” was introduced for the first time during the 2007 drought and reintroduced in 2012 during another drought.
