How does a septic system work?
Conventional septic systems are the most common type of septic system (the others are innovative/alternative (I/A) systems and cesspools). A conventional system includes a septic tank, distribution box, and soil absorption system (SAS). The septic tank separates the solid and liquid wastes and the SAS provides additional treatment before distributing the wastewater to the environment.
Why are failing septic systems harmful?
Inadequately treated wastewater can transfer diseases such as dysentery, hepatitis, and typhoid fever to animals and humans. Failing systems also leak excessive nutrients and bacteria to rivers, lakes, and the ocean, destroying plant and animal habitat, closing beaches, and hurting the environment.
How do I know if my system is having problems?
Some clues:
- Muddy soil or pools of wastewater around your septic tank or soil absorption system.
- Sewage smells around your system or inside your house.
- Backups when you do laundry, take showers, or flush the toilet.
Call the Board of Health if you notice any of these symptoms.
What are the most important things to do to take care of my system?
Pump your system at least every 2 years. Remember to use a licensed pumper for the Town of Wilmington. Conserve water. Don't dump non-biodegradables, such as paint, grease, acid treatments or trash down your toilet or sink.
Will additives help my system?
There isn't one on the market that can make a failing system pass inspection. MassDEP issues permits for septic system additives, but only to ensure that they will not harm your system or the environment.
