Design Tools for Small AFOs

This spreadsheet design tool is used to assist the Sprinkler Vegetative Treatment System  engineer in determining the flow rate, pipeline friction losses, elevation losses, pump capacity, and required horsepower for the pump station. This tool also evaluates the water flow characteristics in the towable sprinkler  system.  Here individual nozzle performance is evaluated along with tube friction loss and water velocity.

Small AFO VTS Demonstrations

The Animal Feeding Operation, also called the Livestock Producer Environmental Assistance Project (LPEAP), provides financial and technical assistance to small livestock producers who are concerned about protecting water quality and preserving the environment, but are exempt from current regulatory requirements.

The project purpose is to construct on-farm demonstration sites that minimize environmental risk using new concepts and alternative technologies. All demonstration projects are available for viewing by all producers.
