DIY Low-tech Water Filter System
How to create a low tech water filter for very little money. It has applications for those that are looking for a preparedness approach to water collection.
We take clean water for granted here in the USA. In many parts of the world, clean and safe drinking water is still a problem. There are more organizations than ever before working on getting clean water to the people who most need it, and more filtration systems for both families and communities available now. We’ve still got a long way to go before the hundreds of millions of people around the world without access to safe drinking water will no longer have to worry about getting sick.
This article from TreeHugger give you the details you need to create a low tech water filter for very little money. It has applications for those of us that are looking for a preparedness approach to water collection. This low tech water filter solution requires no electricity, has no moving parts, and can be built affordably with locally available materials. Just the thing that might be needed in an emergency situation after an earthquake or flooding.
This option for a low tech water filter uses a BioSand Filter (BSF), which puts natural biological processes to work to remove pathogens from contaminated water, and which is a low-cost, low-maintenance, and long-lasting solution. Originally developed in the ’90s by Dr. David Manz at the University of Calgary, BSF systems are essentially a step up from the traditional slow sand filter, and are considered to be an effective method of treating water at the point of use, and one that can be built from local materials, right where it’s needed.
