The Water Shortage in Namibia

1.0 Introduction

This report is going to compare the possible methods to solve the lack of water problem in Namibia. I will compare methods of recycle the sewage water and the water transfer, and it will be analyses by three filed which is the cost and environmental impact or resource.

2.0 Background

I am going to look at the arid problem in Namibia. Nomadic herding are the mainly career in Namibia, the erratically annual rainfall is over 600mm, also the cutting of tree is not in control, and there is a big scale between rainfall and pasture (David, David and BEN, 2004). Obviously, we have some requirement have to consider during choose a method to solve the problem, and I was chosen the cost, Environmental and the resource, it is because we have to depends on can Namibia carry the cost and the resource with their quality, what will be affect the resident in case are also important.

2.1 Recycled Water

Firstly, recycled water which was waste are the way to solve the problem of water shortage, it could sounds like cannot be drink even after cleaning, Singapore possibly is a confidential example, there is a product which is call NEWater was built since 1990s, and residents in Singapore is now using the recycle water for different types of use, especially for drinking (Kaplan, 2010).

2.2 Transfer the Water

Next, the other method to be a solution is to transfer the water. As we can be seen from the map (Google, 2010) above, the region of the Namibia is near the seaside and there is a park which has some water resources. For example, the project which held in China, is transfer the water from south to north, is using different way to transfer the water, try to arrange the water to be more equalize (Jeremy, B., 2003).

3.0 Comparison of options

It will be compare the methods with recycled water and transfer the water by three requirements below.

3.1 Cost

In Namibia, there is a big range between the rich and poor resident, the scale could be about 7times as normal between them, but both of them still have to pay the tax for the government, so it have to depends on can the government carry the project fee, if government cannot bear the it, the pressure probably will transfer to the resident as the past (Michael, H. and Jonathan, B., 2002).

Moreover, held the method with recycled water, we have to consider about to build a filtration plant effluent, because it have to be filtrate by four step to attend the standard for drinking. Also, the cost of transfer water will be decrease (Anderso, J., 2000).

On the others hand, transfer the water
