From April through October 1977, a new sub-surface irrigation system design was tested and evaluated in an applied situation. The purpose of this research was to study the practical application of the design and the collection of data for development of design, construction and maintenance guidelines.
The study has proved the practical applicability of the "Sub Surface Infiltration System."
