State Summary

● Biosolids in Wyoming are mostly applied as soil amendments on agricultural land; some larger cities have successful composting programs that distribute biosolids compost locally.

● Biosolids that are not land applied are mostly used as alternative daily cover (ADC) on landfills.

● Only 12 mechanical water resource recovery facilities (WRRFs) operate in the state. The vast majority of water resource recovery facilities (WRRFs) have sludge lagoons that are cleaned out only every 10-30 years.
