Water - Hydraid BioSand Filter

Cascade Engineering developed a plastic, easily transportable water filter for the developing world.

In 2007, Cascade Engineering entered into a partnership to address the global safe water crisis. Nearly 4 million people across the developing world die each year from unsafe drinking water and almost half of those are children. Lack of access to safe drinking water is the largest cause of death for children in the developing world.

Cascade Engineering was approached for help in designing and manufacturing a plastic version of the concrete BioSand water filtration system that is currently in use today in the developing world. The concrete water filtration system weighs 300 lbs. and is difficult to transport, inconsistent in quality and incompatible to scale for the market. We have designed, tested and manufactured a plastic HydrAid BioSand filter that weighs only 8 lbs. empty, is easily transported, is easy to install and serves the needs of 8-10 people daily (47 liters/hr). Plans are in place to manufacture and distribute 300,000 filters, along with education on the health benefits of clean water.

The development of the HydrAid BioSand Filter exemplifies our belief that sustainability drives innovation, and something that is good for our society can also be good for business.
