Cost and energy inefficient irrigation

Water shortage

There is a lack of adequate quantities of water of a sufficient quality.

In many countries, irrigation pumps operate on fossil fuel. These pumps are costly to operate, require frequent maintenance and are polluting as they emit a lot of greenhouse gases. In other cases, drip irrigation is becoming obligatory to reduce water usage in agriculture. However, due to the required pressure, drip irrigation increases energy consumption by 10 times and with it the cost for pumping.


Barsha Pump

The Barsha pump is a hydro-powered irrigation pump. It can be placed in a flowing river or irrigation canal and requires no fuel or electricity to pump water 24/7. The pump involves only one moving part and therefore requires virtually no maintenance. This results in significant cost savings for the end user and makes the Barsha Pump ideal for remote areas.
