The Act 537 Program is generally administered by local entities and covers any sewage facility, whether it is a municipally-owned plant or an on-lot disposal system (septic system). Malfunctioning systems, regardless of type, pose a threat to public health and the environment.

Pennsylvania Department of Environmental Protection (PADEP) plans to update the code regulating comprehensive sewage management plans, which are submitted by the responsible local agencies/parties for PADEP-approval.
