The purpose of this paper is to compare the effectiveness of the Hydraway (Trademark) edgedrain, which is manufactured by the Monsanto Company, with the Ohio Department of Transportation's standard 4-in. pipe underdrain without fabric wrap. The 650-ft-long test sections are contiguous, constructed at the same grade, and have separate outlets. The U.S. Geological Survey, Water Resources Division, installed equipment to measure the discharge from each test section. Preliminary results from the monitoring devices are not conclusive. There have been too many gaps in the data. For various reasons, such as damage from lightning, an automobile accident, and at times water backing up in the ditch, complete data for the most significant rainfall events are not available. Neither system has shown consistently superior performance over the other. The costs for the Hydraway on the two projects in 1985 were $4.10 and $5.50/ft. The costs for three projects in 1986 and 1987 were $2.42, $2.80, and $2.85/ft. This compares to an average cost of $2.50 to $3.00/ft for the standard pipe underdrain. Collection of data will be continued until matching data for the two drainage systems can be compared and definite conclusions made.
