Watertightness is critical in onsite treatment system tanks, and in risers, lids and inlet and outlet piping. A septic tank or pump tank that is not watertight can cause a number of problems:
Groundwater or surface water leaking in will cause hydraulic overloading of the drainfield and may flush solids out, eventually plugging the field.
