When You Can't Afford A Berkey....

Water is a basic need, and dirty water kills lots of people every year. Luckily there are lots of ways to make water drinkable.  No-Tech Magazine has a good review of OHorizon's open-source biosand filter plans.  It is a relatively permanent solution, with a concrete case, yet only costs a few dollars each to make in quantity, as the form is made of wood.  If you want the plans directly, go to OHorizons and fill out their form.
