Wastewater

Extension at the University of Nebraska–Lincoln is actively involved in programming that helps homeowners, industry, and youth audiences understand onsite wastewater treatment systems for handling domestic sewage. Treatment of wastewater using onsite systems, such as septic tanks and drainfields, plays a very important role in protecting the water and environment of Nebraska and supporting economic development. As a result of Extension programming, Nebraskans benefit from improved water quality and a cleaner environment.
