The mango groves follow the hills and valleys of the local topography, creating a challenging work environment for farmers. Higher pressure is required to transmit water to irrigate the plots located uphill of the water line; lower pressure is required to feed those that are downhill. Farmers would physically go to the water head to manually change the pressure, as needed. Over time, various pressure-reducing applications and accessories had been added to the valve to reduce the need for manual intervention, but this complicated the system and made it difficult to maintain the valve itself.
As the old valve wore out, an opportunity arose to find a replacement solution that would enable irrigation at different pressures, without requiring the physical intervention of the farmer, and without the need for additional accessories to control pressure changes.
