The water supply in Madagascar urgently needs to be improved 

The problems:

The inhabitants of Madagascar suffer from the poor water supply. The quality of the water is insufficient in many places, and some of the water has to be boiled for drinking. Supply interruptions lasting hours and days are a major problem due to pipe bursts and disruptions in water treatment. The amount of water available is also insufficient in many places. The capital Antananarivo, for example, has a daily demand of about 300,000 m3 . However, only about 200,000 m3 are available.

Running water in the house is a rarity even in larger cities. The many people affected have to obtain and pay for water daily at a public well or water kiosk. 

Fetching water is often child labour. Children, especially in rural areas, have to carry the water home, sometimes over long distances. This often hinders their regular attendance at school.

The reason for the major problems in Madagascar's water supply 

The reasons for the frequent pipe failures are, among other things, the old age of the water pipes from the French colonial era and the fact that unsuitable pipe material is often used for pipe construction, e.g. PVC pipes.

In addition, the population in Madagascar's cities has grown enormously. As a result, the procurement and treatment of water has fallen far behind. Also, the financial means to improve the water supply have not been sufficiently available until now.  

The Development Aid Project for improved quality in the construction of drinking water pipelines 

 

For the reasons mentioned above, we have proposed to the state water utility Jirama to send two technicians to Switzerland for a fortnight for training in the construction of pipelines with HDPE pipes and exchange of experience with Swiss experts. The two technicians arrived at the end of February 2023.

Further measures for a good drinking water supply in Madagascar.

In Madagascar, 35 projects are pending, some of them larger, to improve and expand the drinking water supply. We hope that it will be possible to motivate drinking water experts from Switzerland to travel to Madagascar in order to impart additional know-how to the experts on site. This would be an effective contribution to the urgently needed improvement of the drinking water supply in good, sustainable quality.
