Iranian Researchers Develop Off-Grid Water System to Transfer Water to Remote Areas

“This system is designed to solve the problem of excessive consumption and wastage of water, reduce the consumption of electrical energy, use greywater, reducing the volume of water consumed in the treatment plants and the cost of energy in the pumps,” said Ahmed Yazerlu, the executive director of the project to produce a system to pump water without any need to electricity.

He said that the off-grid system operates with compressed air or air pressure.

“This system puts the 5-liter tank under 50 atmospheric pressure by means of a pump and compressed air production. The volume of tank pressurization system depends on the number of times of use and the volume of water storage,” he explained about how their water pump system works.

“Almost 0.8 bar of pressure is needed for every emptying of the water tank, which is gained by 12 pumping times, and after the pressure rises, the gas valve of the air outlet is opened so that the air is pressed into the water tank under air pressure, then the water in the tank is transferred to the favored area,” Yazarlu explained more.

According to the researcher, this system can be used in areas where there is no electricity and it can be used for pumping water from springs to reservoirs or for irrigation use by farmers and also herders, and in remote villages and tourist resorts, etc.

He also said that the system can pump greywater for industrial uses to cool off machinery.

"According to the hydraulic system used in this device, it is possible to supply the output water flow rate and required pressure up to 50 atmospheres, something that is almost impossible in horizontal centrifugal pumps," he said

The researcher said that their water pumping system has successfully been tested by the North Khorasan Province water administration.
