Hassan Kheir, 74, another villager, described the mobile stations as a godsend, as groundwater in the region "has dried up".

Some 45,000 people now have access to drinking water directly from the ocean in Beddouza, about 180 kilometers northwest of Marrakesh, as a result of three monobloc stations.

These units can potentially cover a radius of up to 180 km, according to Yassine Maliari, an official in charge of local water distribution.

With nearly depleted dams and bone-dry water tables, some 3 million people in rural Morocco urgently need drinking water, according to official figures, and the kingdom has promised to build 219 more desalination stations.

Monobloc stations can produce up to 3,600 cubic meters of drinking water a day and are "the best possible solution" given the ease of distributing them, Maliari said.

For cities with greater needs, like Casablanca, larger desalination plants are also under construction, adding to 12 existing national plants with a total capacity of nearly 180 million cu m of drinking water a year.
