Biosolids are nutrient-rich organic materials created through the treatment of domestic wastewater generated from sewage treatment facilities. When properly treated and processed, these residuals become biosolids.   Noted benefits of biolsolids include:

  • Improve productive soils
  • Stimulate plant growth
  • Reduce soil erosion
  • Conserve landfill space
  • Increase soil water holding capacity

WSWMD supports member communities with the management of their biosolids and can help coordinate commercial partners and state regulators to ensure disposal requirements are met.
