Study Notes
Canadian Invention Brings Water to African Villages
- Researchers from the University of Waterloo, Ontario, developed a low-cost, shallow-well pump for developing countries.
- The pump was designed to be durable, affordable, maintainable, and manufactured locally.
- The pump was inspired by a traditional hand-operated water pumps used by the Mennonite community in southern Ontario.
- The pump uses PVC tubing, which is inexpensive, readily available, and rust-resistant.
- Over 11,000 pumps are being used in 13 developing nations.
- The pump design can be adapted to local conditions. For example, in Sri Lanka, a leather washer is used instead of a plastic one, and in Malawi, the spigot is made of black metal to prevent hyenas from chewing it.
- This invention has brought clean drinking water to many villages in developing countries.
Using Science and Technology to Solve Problems
- Two Canadian scientists, Alan Plumtree and Alfred Rudin, invented a reliable hand-operated water pump in 1978.
- The pump's design met specific criteria for developing countries:
- Durable enough for 18 hours of continuous use.
- Affordable for people in poorer countries.
- Simple enough for villagers to maintain and repair.
- Designed for local manufacturing to create jobs and ensure the availability of spare parts.
- This exemplifies how science and technology can be used to solve real-world problems.
Canadian Invention Brings Water to African Villages
- Researchers at the University of Waterloo, Ontario developed a low-cost, shallow well pump that is easily used in developing countries.
- The invention was inspired by a hand-operated water pump used by a Mennonite community in southern Ontario.
- The pump was designed to be durable, affordable, simple to maintain and repair, and manufacturable in developing countries.
- The new pump incorporated polyvinyl chloride (PVC) tubing instead of traditional iron and steel.
- PVC is inexpensive, readily available worldwide, and rust-resistant.
- Over 11,000 pumps are being used in 13 developing nations.
- The pump design has been modified for local conditions, like using a leather washer in Sri Lanka and a black metal spigot in Malawi.
