Utilizing pipelines for water delivery reduces the delivery of sediment-attached nutrients to surface water.

Not Applicable

Piipline eliminates surface flow that could pick up salts from an unlined ditch. The pipeline also eliminates evaporation, which can 

concentrate salts in irrigation water.

The action eliminates seepage from earth canals which can move soluble salts to the ground water. 

Pipeline eliminates surface water flow reducing contaminated water runoff.

The action eliminates seepage losses from canals, which reduces the potential for movement of pathogens to groundwater. 

Pipeline can collect and convey excessive subsurface water to suitable outlet.

Not Applicable

Pipe will convey water and make it possible to use more efficiently.
