Trench Slope Tool. The app has a feature to notify if the measurement is done correctly and accurately. 3 addresses flow adjustments to be made to a sewer’s PDWF, DF, minimum EP and maximum EP where the sewer is to receive flow from a fixed-speed pumping station. For TYPE A soil and a trench depth of less than 12 feet for a trench open 24 hours or less, the steepest maximum allowable slope is 63 degrees from the horizontal. Sloping involves cutting back the trench wall at an angle that is inclined away from the work area of the excavation. The 2019 Trench Safety Stand Down will focus on trench and excavation hazards and reinforce the importance of using protective systems.

This translates to a 0.5H: 1V incline and is shown below. The new NDS app is the perfect tool for determining runoff and system requirements on the go. Note 2: These are the minimum sloping requirements. No, it doesn't compute volume from gallons.
