Objective

The objective of this project is to evaluate and demonstrate effective techniques and/or systems to reduce environmental pollution from dairy milkhouse wastewater and disseminate the results to dairy producers in Minnesota.

Need or Impact

Many small and mid-sized dairy operations in Minnesota need to upgrade their milkhouse wastewater handling systems to comply with Minnesota Feedlot Rules (Minnesota Rules Chapter 7020). Producers 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 practical and technical information needed to select and design effective and economical systems.

Project Status

In progress.
