Installation of Drain Tile for Subsurface Drainage

This paper reports current progress in installation of tile drains for subsurface drainage. The Soil Conservation Service provided technical assistance on installation of 24,059 miles of tile drains during the 1959 fiscal year. The paper gives benefits of tile drainage, and describes tile used in combination with surface drainage and current procedures used by the Soil Conservation Service in making drainage investigations. Recent changes in the American Society of Testing Materials specifications for clay and concrete drain tile are discussed. Recommendations are given for use of concrete tile under acid and alkali conditions. Recommendations for gravel filter requirements are given.
