ABSTRACT:
A system and method to remove surface water from a watershed atop a hill behind a bluff to an outfall point near a toe of the bluff, and a method to build the system. The system includes a catch basin structure and a catch basin drain pipe directionally bored from the catch basin structure to the outfall point. The location of the catch basin is determined based on a location of the outfall point and a desired slope of the catch basin drain pipe. The catch basin structure has a catch basin with an opening near its bottom, and a cover structure that provides a sculpted, rounded and smooth transition from the opening to a reducing pipe coupled with the catch basin drain pipe.
