Objective

The objective of this project is to build on previous research to evaluate and demonstrate four effective techniques and/or systems to treat dairy milk house wastewater in southeastern Minnesota.

Need or Impact

Many small and mid-sized dairy operations in southeastern Minnesota need to upgrade their milk house wastewater handling systems to comply with Minnesota Feedlot Rules (Minnesota Rules Chapter 7020). Producers in southeastern Minnesota want systems that perform reliably, meet environmental regulations, fit their management practices, and are economical to install and operate. Performance, cost, and management information gathered for this project will provide producers, engineers, Extension educators, and technical staff with practical and technical information needed to select and design effective and economical systems.

Project Status

In progress.
