Beneficially reusing nutrients through the Metrogro Program puts the District’s vision of enriching life through clean water and resource recovery into action.  Biosolids are the nutrient-rich organic product generated during the wastewater treatment process.  The Metrogro Program recycles biosolids to agricultural land in a safe and environmentally sound manner.  Farmers using Metrogro can increase productivity and reduce costs.   The Metrogro Program has received national recognition and has been used as a model by the EPA.

The District treats 40 million gallons of wastewater every day, producing clean water and a nutrient rich organic product called Metrogro, which is used by area farmers to grow crops.

Prior to application to farm land, Metrogro is temporarily stored in large tanks at the Nine Springs Treatment Plant. Each tank holds over 6 million gallons of Metrogro

Metrogro is transported to farms in fully enclosed trailers.
10/3/2013 1:24:00 PM
At the field application site, Metrogro is transferred to a “nurse tank”. Application vehicles load directly from the nurse tank.
10/3/2013 1:24:00 PM
Metrogro is applied using subsurface injection. Highly specialized equipment is used to apply Metrogro. The equipment utilizes a computerized system to control application rates. All Metrogro is applied using subsurface injection techniques.

Metrogro is applied to 5,000 acres of farmland in a safe and environmentally sound manner, following all requirements specified by the Wisconsin Department of Natural Resources and the United States Environmental Protection Agency.
10/3/2013 1:24:00 PM
All farms receiving Metrogro applications must be approved for use following a process administered by the Wisconsin Department of Natural Resources. As part of the approval process, environmentally sensitive areas that may exist on the farm are identified. Metrogro may not be recycled in these areas.
10/3/2013 1:24:00 PM
Soil samples are collected from each field and analyzed by the UW Soils and Plant Analysis Laboratory. Soil test information is needed to determine the proper Metrogro application rate.
10/3/2013 1:24:00 PM
Records are kept for all fields receiving Metrogro applications, with the information being provided to the Department of Natural Resources annually.
