West Central Wisconsin Biosolids Facility
In 1997, a Wisconsin Department of Natural Resources standard limited the spreading of sludge to only 6 months a year due to the ground being frozen. The regulations prompted local officials to endorse the construction of a new biosolids plant in Ellsworth.

Producing a Higher-Quality Sludge
The facility produces a higher-quality sludge. Local sewage is treated in River Falls and transported to Ellsworth, where fewer restrictions are placed on spreading the end products.

The Ellsworth facility handles waste from several Western Wisconsin communities. The plant mixes lime and fly ash with dewatered sludge so that the end product can be used as a lime supplement for farmland. The local plant is monitored 24 hours a day and daily lab tests assure that state mandates are being met.
