A pump made by a small Nepali engineer shows that he can change Nepal's fields


When Thapa Pratap was raised in the village of Laila in the south of Lalitpur, I watched the plants of his parents and the corn on their balcony and waited for the rain. He often wonders how hard work can be reduced if possible to bring water from the nearest river.

Thapa went to study engineering at Delft University in the Netherlands, where he was obsessed with how to solve his family's irrigation problems in Nepal's mountains in a cheap and sustainable way.

With a colleague at the Dutch School, devised a unique pump that comes from kinetic energy to flow the water and uses it to pump water. Like all breakthroughs, is the simplicity of the technology that makes it workable.


Contact the Al Barsha pump (after the word "Matar" Nepalese) has won the Thapa award in many awards, including the Philips Innovation Award and T-Points. This was followed by a record of the base in the Netherlands in 2013 to promote the pump.

Thapa was captured immediately in Europe, but despite the success there, it was designed to remember Nepal. So, six years ago, he was carrying a number of prototype models and tested them successfully to irrigate nearly 130 hectares of flats over the Indrawati, Tresuli and Tama Kosi rivers.

"It's ironic that two-thirds of the fields in Nepal depend on the rain when we are a country with six thousand rivers," said Thapa, who studied industrial engineering in India and a master's degree at the Lalitpur Engineering Institute.

At present, 131 parcels have been deployed in 30 provinces with farmers' support from the State Agricultural Engineering Directorate, the Office for Agricultural Development in the Regions and international institutions. Depending on the capacity, the pump costs between Rs. 160,000 and 280,000 rupees.

The beauty of the pump is that it uses a natural flow of water and does not require fuel. So do not release greenhouse gases, and operating costs less.

The pump contains a special spiral tube where the water helps to compress the air, which in turn raises the water to a maximum height of 20 meters or a distance of 2 km.

Yuvaraj Shrestha owns 1 hectare above an apartment above the Tama Kosi River in Ramechhap, and uses 500,000 rupees a year to sell vegetables. The main problem is relying on the rain, although the river flows through the glacier flows into agriculture.



But the following year, after installing a subsidized pump, he received more than three million rupees from his ranch. This pump carries 12,000 liters of water per day from Tama Kosi. The apartments along the Tau Kozi that are accustomed to being exchanges in the dry season are now lush green all year round.

"Everything starts with this pump, and that is the key to my success," he said.

In Sindhuli province, Arkhun Kumar Khatri of the village of Ratumit ran subsistence agriculture in rainwater. He is now raising water from the Sun Kusi River, which is 14 meters from his farm, with the pump of Al Barsha. "I do not think the pump can lift the water without electricity so I can see it myself, our life changes," he said.

Al Barsha pumps now carry this miracle to 12 countries including Indonesia, Spain, Turkey and Zambia. Thapa maintains the design of comments from farmers.
