"It's a technique that embodies the real meaning of sustainable development and protection of the environment," he said.
Razzouki, a nomad from the M'Hamid region, was concentrating hard on figuring out how the waterpod works.
"This could resolve many of our water problems," he said, noting that the box was light, and "we won't have the problem of salty water everywhere we go."
M'Hamid El Ghizlane, Morocco's gateway to the Sahara, is an oasis on the edge of the Draa valley surrounded by rolling sand dunes, 40 kilometers (25 miles) from the Algerian border.
The construction 40 years ago of a hydro-electric dam further up the valley to provide for the growing population and tourist trade at Ouarzazate, along with the relentless desertification of the region, has taken a heavy toll on water supplies.
So there are high hopes for the waterpod, one of which can produce six liters of pure water daily from 12 liters of brackish water, according to its creators.
They give it an estimated lifespan of 20 to 40 years, with just a daily clean needed to keep it in good condition.
