Finding the Required Slope of a Sewage Pipe
Sewage pipes running from a house to the street must slope downward at a rate of inch per foot in order to drain properly. To find the required slope, apply the rise-over-run formula, making sure both measurements use the same unit.
Write the slope formula and substitute:
Convert the run to inches so the units match ( foot inches):
Simplify by dividing by :
The required slope of the pipe is . This means the pipe drops inch for every inches of horizontal run. The slope is negative because the pipe must angle downward to allow gravity to move the sewage toward the street.
