Background The Soqotra archipelago is located in the north-western part of the Indian
Ocean in the Gulf of Aden about 400 km south of the Yemeni Coastline.
There are four islands in the group, namely Soqotra (125 x 42 km) and the
smaller islands of Abd Al Kuri, Samha and Darsa. Darsa is uninhabited
and Samha and Abd Al Kuri are sparsely populated. The population of the
archipelago has been estimated to be about 44,000. It is one of the poorest
and most disadvantaged group of islands anywhere. The water production
for both Hadibo and Qalansiyah does not cover the water demand for the
inhabitants and other activities. The existing water supply distribution
system in Hadibo was not properly designed and 70% of it needs
replacement while 30% was recently installed in 2005. The continuity of
water supply is daily but only for 12 hours per day.
Description of project The project aims improve the quality of life of the population in the
Hadibo and Qalansiyah by reducing health risks related to the use of
insufficient drinking water (in terms of quantity and quality and lack of
wastewater collection and treatment .This goal would be achieved through
the provision of basic volume of safe water through new and /or
rehabilitated production and distribution systems and sanitary schemes
improvement of the operational efficiency of the rehabilitated and/or
upgraded water supply and scheme , and an improvement of the hygiene
awareness and health attitudes of the population.
