As a follow up to the government subsidized project for small farmers a few years before, a co-operative of date farms in Southern Tunisia bought 16 NPI water tanks for the irrigation of date palms. The date palms nurseries are located in a strip of 2,500 hectares of along the border with Algeria, in a desolate area in the Northern Sahara.
In the early 1970s, an enormous underground aquifer was discovered in this part of Tunisia. In the years that followed, several oases were created to develop agriculture in this area. In this area a strip of 2,500 hectares of crops including (date) palms was created.
The crops and thousands of palm trees are irrigated using a sophisticated system fed by the central water storage, which consists of dozens of metal water tanks. Relatively low tanks with a wide diameter were chosen; 16 tanks of 19,14 x 1,52 meter. The 41 water tanks of both phases of this project allow the production of around 20,000 tonnes of dates annually.
