Slotted Drain

Slotted Drain pipe is a practical, aesthetically pleasing inlet for the efficient removal of surface water on streets and highways. It also is widely used in parking lots and similar locations to remove sheet flow without complex multiple grades or water channeling devices. Slotted Drain pipe is fabricated from CONTECH Corrugated Steel Pipe, which is cut along a longitudinal axis. A trapezoidal or straight-sided grate with reinforcing spacer plates is welded in place to form a 1 3/4”-wide slot opening which collects runoff and channels it to the pipe below.

CONTECH Slotted Drain has been used at countless locations throughout the United States for more than 40 years simply because it is the most effective solution to water removal problems. It is a versatile and cost-effective solution for surface water removal on many sites.
