Interceptor® SuperSlope

Point Inlet Refinement

The Interceptor® SuperSlope high-volume sloped drainage channel augments the advantages of PDX with our integral frame and grate. SuperSlope is the perfect interceptor drain system for applications that require traversing more extreme grades or where extra inflow capacity is needed. In a sump location, flanking inlet structures with SuperSlope have been shown to limit inlet bypass and reduce cost by reducing the number of structures needed.

For over 30 years, ABT's skilled team has made it our top priority to provide outstanding service and top-of-the-line drain solutions. Our Interceptor sloped highway drain systems and other drainage products are uniquely designed using materials of the highest standard.

We take pride in the fact that we manufacture some of the most extensive, reliable, and versatile lines of channel drains, grates, and water management solutions in the road and highway industry.
