The way industry professionals maintain onsite wastewater treatment systems can directly impact the safety and lives of people living nearby. Ensuring that manhole lids are secure and that the system includes a secondary safety device can protect health and save lives.
As an industry, having access to components such as septic and pump tanks and ATUs is necessary and facilitated by large-diameter manhole access at grade. Some regulations may still allow septic system manhole lids to be buried with 6 to 12 inches of soil, but the general regulatory trend has been to bring all components needing regular maintenance to grade.
