The Mango Irrigation Challenge in West Ethiopia

Mango is one of the main fruit crops produced in Ethiopia, both for domestic consumption
and exportation. The fruit has significant importance amongst Ethiopian farmers as well as for the whole country.
It has potential to act as an economic safety net by generating employment and enabling processing and marketing opportunities.
The crop requires tropical or subtropical conditions with high humidity.
In west Ethiopia, a large scale farm owner of an existing rain-fed mango plantation of 1,700 hectares, was faced with a problem.
Although the farm is located in a rainy area receiving about 1,200mm of rain per year, 9 months of the year the crops would receive water,
while during the remaining 3 dry months, precipitation is close to zero.
The farm owner requested an irrigation system that would provide water for the three dry months and would enable fertigation all-year-round.
The rocky soil would make the digging and pipe laying a challenge by itself.
All of the system's hydraulic and electric safety measures were taken into consideration in the design and implementation, in order to avoid water hammers, excess pressure and trapped air.
