The Department of Public Works uses the following criteria to prioritize areas for septic-to-sewer connections
Although a carefully maintained, properly used private septic system is generally safe, many of the systems in Anne Arundel County have unique challenges that can contribute to system failure. The Health Department has identified problem areas in the County where conditions could lead to septic system failures, resulting in poor groundwater quality and risks to public health. These On-site Wastewater Management Problem Areas are characterized by:
Properties located near existing public sewer system infrastructure are easier to connect to the County’s existing sewer network.

How do Septic Systems Impact our Health and our Waterways?
More than 40,000 properties in Anne Arundel County use on-site septic systems to treat their wastewater which can significantly pollute water under certain conditions.
In dense subdivisions located close to the water, even properly operating private septic systems can release up to eight times more pollutants into the Bay than the County’s water reclamation facilities. Learn More →
When a household septic system is not properly maintained, untreated wastewater can overwhelm the drain fields and surface to the ground, polluting the water supply. Learn More →
When systems do not operate properly or are too close to private drinking water wells, contaminants from the wastewater may even reach drinking water. Learn More →
Septic System Maintenance
If you have a septic system but your property is not eligible for the program, you can still take steps to protect the environment and prolong the life of your septic system.
