Biosolids Processing

From sewage to farmers’ fields, biosolids processing is a miracle of sanitation science. While the primary product of the treatment process at Four Rivers Sanitation Authority is clean, pure water, that’s not all that is produced by the activities of the plant. Since we are constantly searching for more efficient uses of material and energy, over decades we have invested in a robust Biosolids Processing Facility.

This equipment takes the solid materials that settle out of the water and – through a complex, scientifically calibrated process – transforms what was once raw sewage into useful energy, heat and fertilizer. To the general public, the concept of Biosolids Processing might seem odd, but by making the best use of naturally-occurring sources of energy and nutrients, we are able to reduce our environmental impact.
