When animals are free ranging "dilution is the solution to pollution." Animals that range freely tend to distribute their waste over a large area and the natural processes disseminate the waste. When animals are confined the waste is concentrated in one spot and it becomes part of the management of the animals. Animal waste management is no longer an option in a livestock business; it is a requirement. A plan for the collection and disposal of animal waste must be part of any livestock facilities plan. Failure to provide adequate waste management collection and storage facilities, and disposal equipment can lead to pollution problems with legal complications, animal health problems, increased production costs, and a generally undesirable working conditions. In most states, confinement operations must have a comprehensive nutrient management plan. There are three aspects of animal waste management:

1. Waste handling

2. Waste treatment

3. Waste disposal

When the decision is made during the planning process, the producer can choose from a variety of waste handling, treatment and disposal systems to manage the animal waste. Selecting a system after the facility has been built limits the options.
