The SSF/x and SSF 1.25
Slow Sand Filters
Potable water from surface water sources

"First, we continue to get impressive service from your SSFx sand filter we installed in the small village of La Cienaga in central Mexico. The filter has been operating for a year-and-a-half and has continued to produce bacteria-free water under difficult circumstances. Those circumstances are that the source water has an extremely high sediment content - at its worst the water is yellow/orange in color. Even when the community well was flooded with sediment during the rainy season and delivered very dirty water to the sand filter, the SSFx continued to produce clear, bacteria free water." -Larry Siegel, 2008
