How to Be Septic Smart

Being Septic Smart means properly maintaining your septic system and avoiding activities that can shorten its lifespan and cause costly repairs. 

Approximately 30,000 properties in Baltimore County are served by private septic systems, rather than the public sewer system. These onsite sewage disposal systems (OSDS) are a long-standing method for collecting, treating and disposing of household sewage from the kitchen, laundry and bathroom. If properly designed, installed and maintained, they can effectively remove contaminants and protect the groundwater, streams and waterways leading to the Chesapeake Bay. 

Know Your System and Location

It is important for property owners to know where their septic system is located on their property and be familiar with their OSDS drainfield, and areas designated for future repairs. It is critical that homeowners protect their system from tree and shrub roots, parked vehicles, livestock or excessive rainwater drainage from roof drains or sump pumps. If you are uncertain where your system is located, request well and septic records for your property.

Homeowner Resources

All septic systems require regular maintenance, pump-outs and inspection—which prevent costly repairs. Most residential systems should be pumped every three to five years. These time intervals may vary depending on usage and the type of system. Learn more from these resources:
