Central area dams nearly empty – Save water
The Omatako dam is empty. The Swakopport dam is estimated to have only 4,112 million cubic meters of possible 63,489 million /m³ left. The Von Bach dam is filled with water via canal and pipeline from Kombat and Berg Aukas, but has only 5,655 million/m³ of possible 48,560 million/m³ left as on Monday the 21. November 2016.
Windhoekers were supposed to have been saving water since April last year, but have never reached the prescribed target. The last few month people and businesses were asked to save 40 percent of their normal usage but have never succeeded. Less than 30 percent of their normal usage have been saved, nearly 10 percent off the target. If it does not rain, the dams will be empty before Christmas!
NamWater stopped pumping water from the Omatako dam to Von Bach dam on 23. August this year, when the dam was empty. No water is being transferred from Swakoppoort to Von Bach anymore, since the last bit in the dam is being used for Karibib and the Navachab mine.
Namwater announced, that all different dams in the country were filled to 24,6 percent of their full capacity on Monday 21. November 2016. This means that there were 176,186 million cubic meters of water in all the dams.
Last year at the same time there were 35,1 percent and 245,238 million / m³ available.
The Hardap dam at Mariental can store 294,593 million/m³. This means that all water in Namibias dams available at the moment would not even fill the Hardap dam! Namibias largest dam has 0nly 72,730 million/m³, which is less than a quarter of its storing capacity. If all 17 dams in the country are full, they store 705,855 million/m³. The situation at the moment is alarming and more than half of the first half of the rainy season (October-November-December) has delivered no relief - not a single drop of water entered our dams!
