7. Determine the volume of excavation for each of the storm sewer catch basins. Given 48" x 24" inside dimensions and 6" wall thickness, assume that the bottom of the trench is a 6.00 feet by 4.00 feet. Add 1.5 feet to the top of casting to invert distance to determine overall trench depth. Again, assume that the soil is tough clay (0.25' Horizontal to 1.0' Vertical). Catch Basin Trench Bottom Volume Top Area Average Area Number Depth Area Ft² Ft² Ft² Feet Yd³ CB 2 24 CB 3 24 CB 4 24 CB 5 24 8.
