A field spreader truck distributes biosolids at the ranch


Biosolids are a nutrient-rich organic material created from the biological and physical treatment of wastewater. Biosolids can be used to improve soil structure and water retention, and also are used as a slow-release fertilizer. Currently, Fort Collins Utilities applies 70 percent of its biosolids (wastewater sludge) on Meadow Springs Ranch and 30 percent on private farm land.

The City produces approximately 1,900 dry tons of solids per year. Four times per week, two semi-trailers of biosolids are trucked from the Drake Water Reclamation facility to the ranch and spread on concrete pads for solar drying. The solids are solar dried from a consistency of wet earth to a dry dirt (25 percent to 90 percent total solids) and are applied to the rangeland at a rate of two dry tons per acre.

Utilities staff routinely sample soil and groundwater, using results to determine management practices on rangeland, and to comply with state and federal regulations.

National Biosolids Partnership

National Biosolids Partnership

The Water Reclamation and Biosolids Division (WR&B) is committed to proactively addressing the challenges that will arise with respect to biosolids management in the future, especially in respect to city growth, transportation and public acceptance.

In 2014, City of Fort Collins WR&B joined the National Biosolids Partnership (NBP). The NBP is a program that advances environmentally sound biosolids management practices. This helps the City’s current program by improving our current biosolids program to achieve national recognition through an increase in awareness of land stewardship and by providing areas of improvement and best practices for biosolids reuse.
