Abstract:

The Metropolitan Wastewater Management Commission (MWMC) - which serves the cities of Eugene and Springfield, Oregon - promotes the recycling of biosolids through land application as the most environmentally sound way to manage this resource. MWMC has operated a very successful recycling program for almost 30-years, relying almost exclusively on volunteer growers who make their land and crops available for biosolids application. The program has maintained wide public acceptance. Local growers continue to line up to have the nutrient rich biosolids applied to their land.

The recent addition of “Biocycle Farm”, a hybrid poplar plantation, to MWMC's recycling program allows more control and greater options for the biosolids application schedule, reduces processing costs, and will produce a marketable commodity to help offset operating costs over time. Originally proposed as a biosolids only application, recent permitting issues related to temperature control in the receiving stream have presented advantages for increasing the use of recycled water for irrigation on the farm.

The 596-acre Biocycle Farm is located at the southern end of Oregon's Willamette Valley, 10miles north of Eugene, Oregon.
