drainage pipe line slope in south africa

Installing a Residential Sewer Line

If the pipe run is 80 feet, the slope is: 2/80 = 0.025 or 2.5 percent. The standard minimum slope for laterals (in most areas) is 2 percent, or 2 feet of drop per 100 feet of run. The actual slope can be slightly steeper than this target but must meet the requirements of the local code. A slope that is too steep will cause the liquids to run
