The appropriate slab height above finished ground level and the slope of the external finished surface surrounding the slab may vary depending on: The local plumbing requirements; in particular the height of the overflow relief gully relative to drainage fittings and ground level (to work effectively they must be a minimum of 150 mm below the lowest sanitary fixture). Design gradients should be as even as practicable, depending on the number of WCs being served (minimum one for 100mm pipes, five for 150mm pipes, with peak flows greater than 1 L/sec. This will allow the total pipe drop (or fall) to be calculated. It's come to my attention primarily in the realm of on-site septic system design, in the maximum slope of the building sewer to the septic tank, usually a 4-inch ABS or PVC pipe, and then the 4-inch pipe from the septic tank to the drainfield. But there are other issues concerning pitch to keep in mind. Pipe slope drains are used where concentrated flow of surface runoff must be conveyed down a slope in order to prevent erosion. Pipe grade is dependent on the ground surface grade, juggling the pipe it miss obstacles and other pipes, the level of the outfall and depth and soil cover requirements.

Accurately calculating the slope of your drain pipe is essential to the proper function of your plumbing fixtures. If the gradient is steeper than 1 in 40, the liquid may run faster than the solids in the sloping foul water pipe thus leaving the solids stranded, which could then block the pipe. In general, sewer mains should be designed to have a flow rate of 2 feet-per-second during peak dry-weather conditions. Large sewer lines require calculations to determine the proper pitch. or less shall have a downward slope in the direction of flow of at least 1 in 50. GRADIENT = FALL / … For flow rates greater than 10 feet-per-second, the pipes should be designed with anchors or other means of preventing the pipe … To AS/NZS 3500.3.2:2003 "Stormwater Drainage Acceptable Solutions".
