The Department of Water and Sanitation (DWS) has released its weekly report on dam levels which has shown a decrease in the national water storage from 80.9% last week to 80.2% this week. This decrease demonstrates that the winter season is fast approaching and normal rainfalls will also subside.
In that regard, the department calls on everyone to make concerted efforts to use water wisely during this period in order to conserve the current water resources until the next rainy season.
