Eenhana-The estimated volumes of water in the Ohangwena aquifer
have ballooned to 20 billion cubic metres, from the earlier
estimates of 5 billion cubic metres.
The aquifer is currently supplying 40 cubic metres of water per
hour to Eenhana through three boreholes. The agriculture ministry
is now looking at extending water provision to areas of Epembe,
Oshikunde and Okongo in eastern Ohangwena. These areas currently
have no access to piped water and are in dire need of potable
water. This was revealed by the deputy permanent secretary in the
Ministry of Agriculture, Water and Forestry, Abraham Nehemia, who
was happy with the progress in work done on the aquifer.
We will ensure that Oshikunde, Epembe will get water from this
aquifer, depending on available resources, said Nehemia.
Nehemia said although the quality of the aquifer water is good
it is unfortunately rich in fluoride that will require the ministry
to also put up desalination plants in areas where more boreholes
would be drilled to ensure that such water is fit for human
At present, the water to Eenhana is used concurrently with
pipeline water to desalinate the high-fluoride aquifer water. It is
pumped through three boreholes that were drilled at a cost of N$2.6
million each between late last year and May this year.
In 2013 it was estimated that the Ohangwena aquifer has 5
billion cubic metres of water.
Studies on the aquifer, which commenced in 2013, will be ongoing to
determine how the aquifer will react once large volumes of water
Currently, water extracted from the aquifer is only for human
and livestock consumption but not for larger scale usage.
Martin Quinger, a representative of the company doing the
technical work, Bundesanstalt fr Geowissenschften and Rohstoffe
(BGR), said the aquifer stretches about 200 kilometres into Angola
with most of the recharging also done in Angola.
Quinger said 80 percent of water from the aquifer comes from
Nehemia said the Angolan and Namibian governments have established
the Cuvelai Water Commission to ensure that the agreement of
extracting water from the aquifer is in compliance with SADC
protocol on shared watercourses.
While there is a dire need in eastern Ohangwena, several
boreholes were drilled during the drought last year, but have not
had installation work done.
But Nehemia assured that the process of installation has already
commenced in the Zambezi and Kunene regions and will be done in
However, he appealed to the regions with uninstalled boreholes
to identify critically-hit areas as the budget may not...
