Heavy rains push dam levels up
THE country’s average dam levels have increased, with some major dams recording 100 percent capacity
n a statement, Zimbabwe National Water Authority (zinwa) corporate communications manager Mrs Marjorie Munyonga said some of the country’s major dams had started recording increases in water levels as most parts of the country continued to receive rains.
“Dams in the Matabeleland area have shown a positive increase in the latest recording, and a number of community dams have since been recorded full during the festive season.
“The national dam level average has also risen to 49 percent, which shows a rapid change since the last recording, though the figure is still below the national average expected during this time of the year,” she said.
The dam level average is usually around 60 percent during this time of the year.
Mrs Munyonga urged Zimbabweans to use water responsibly.
“The Zimbabwe National Water Authority continues to urge water users in all sectors to use the available water sparingly and to practise rain-water harvesting.
“In case of floods, move to higher ground, also keep watching and listening to radio and television for information,” she said.
Mrs Munyonga urged water users to regularise their usage with the authority to avoid prosecution.
“The authority also appeals to irrigating farmers and other raw water users to ensure that they enter into water abstraction agreements with Zinwa as is required under the Water Act.
“Any use without the necessary documentation is illegal and offenders are liable to prosecution or risk having their supplies disconnected,” she said.
