Access to clean ground water is not as easy as it was in the past. Rising pollution levels coupled with the increasing demand for clean water has led to harnessing ground water in several unsustainable and environmentally degrading ways.

Thankfully though, this can be prevented with the help of sustainable water pumps which can help individuals gain access to clean ground water in a sustainable manner. Here are 6 such sustainable water pump designs that have been doing the rounds of late.

Sun-Sub Submersible Solar Panel Pump

The Sun-Sub Submersible Water Pump is solar powered and features a lightweight chassis along with soft suspension. It is fitted with a 12x120W solar panel array which supplies the necessary power to the pump. When fully functional, the pumping system can supply a stunning 2920m3/h.

NSP Solar Pump by Pumpmakers

The NSP Solar Pump by Pumpmakers is an affordable water pump that is literally maintenance free. It can easily be manufactured anywhere in the world and can extract water from depths of over 300 feet. Powered by solar energy, the pump can also work on cloudy days while a hand crank can be used to supply power at night.

With the capacity to pump over 5000 liters of water every day, the pump can surely be a blessing for those who want to conserve energy and enjoy reduced utility costs as well as an improved quality of life in the process.

Solar balloon Waterpump WIP

The Solar Balloon Water Pump uses both solar and wind energy to power the pump. The pump works on the principle of the solar balloon producing a pulling force as and when the sun heats up the air inside it. The force thus created, will create an under-pressure inside a closed well. This pressure will allow water to be pumped into a reservoir from where it can be distributed to several fields in the region.

Solar Spiral Water Pump

The Solar Spiral Water Pump features a solar powered spiral glass tube that is immersed in a well while the top portion is left exposed to the sun. As the sun heats the water in the well, the steam thus produced shoots up the tube, causing it to spin continuously. This spin motion will, in turn, cause the steam to rise inside the spinning spiral tube. A condenser at the top converts the steam to water again which is collected in a bucket or distributed via a hose attached to the condenser.

Solar Stirling Common Waterpump

This low temperature water pump is considered the best choice for decentralized water supply and distribution. The pump itself is very easy to construct and can be done by anyone with the help of just a few instructions. It is also much cheaper than traditional photovoltaic water pumps and can easily extract water from depths of over 100 meters.

The performance of the Solar Stirling Common Water pump is also very favorable when compared to traditional diesel pumps. While the standard use of the pump is for extracting ground water, it can also be used to pump water to higher ground, or power presses, power saws and grain mills.

Humphrey Pump

The Humphrey Pump has been in use for quite some time now and is considered as one of the most robust water pumps around. This is a fact that has been proven by a 100 year old Humphrey water pump still functional in Australia. Although quite old, the Humphrey pump can be easily modified to suit current needs, thus reducing construction and operational costs while not compromising even a little bit on operational efficiency.

Getting access to clean ground water has become a hassle these days. However, recent developments have given rise to several innovative pump designs that would allow one to gain access to clean water in a sustainable manner.
