Why Drainfield Effluent lines need to be properly sloped
Septic drainfields that treat and dispose of clarified wastewater effluent using gravity need to be properly pitched and never sloped too steeply. Otherwise effluent will run too quickly to the low end of the drainfield line and gravel trench where it is likely to simply break out to the property surface.
If you have to install a conventional perforated pipe and gravel trench drainfield on a steep slope you'll need to run the trenches along the slope or parallel to the fall line, stepping down the slope from trench to trench.
