Engineering clean water

When I lived in inner city Oakland, I loved the way folks in our church community could use their careers and professions to serve their neighbors. Teachers, social workers, medical professionals, programmers, attorneys, etc., all found ways to use their skills and background to work with those around them.

Now that I live in Guatemala, doing community development in a small rural community, I love seeing how engineering can radically alter an entire community’s existence. One of the engineers on staff builds water filters out of cement, fills them with three layers of sand, inserts a plastic tube, and voila: contaminated water goes in, 99.9% pure water comes out. I’d explain how this ridiculously simple concept works, but being a social worker, I’ll just post this image:

It works, it’s simple, and it saves lives. It’s estimated that water-borne illnesses account for 1.8 million deaths every year1. These water filters also prevent illness, reducing absenteeism from work for parents and from school for kids. I love being a social worker, but I’m so grateful for engineers’ creative use of their gifts to love their neighbor.

This two-minute video features the community leader where I work demonstrating the use of the filter:

This Lenten season, although I wish I could drink the tapwater here, I’m so grateful I don’t have to hike up the hill like Judith and all her fellow residents do every day. Cheers!

  1. That is amazing! How is it that just simple sand filters out tiny microbes? If the water can get through, why not the microbes? If filters like these are so simple, why aren’t they more widespread? How much does it cost to build one?

    Great post, Nic.
