Fig. 34.—Catch-basin for Connecting Surface Drainage with Underdrains, be renewed when the wood decays, and is obviously less permanent as an improvement. In some respects, however, the wood construction is more desirable. The inlet may then be a hole in the side of the box at the surface flow line, with iron rods fastened vertically across it. A serviceable and easily constructed catch-basin may be made of the sections of 24-inch sewer-pipe, which should be set end to end in a vertical position and the.
