Why You Shouldn't Build Over or Near a Septic Tank, Carmel, New York

Septic tanks play an important role in basic household functions. If the system is compromised, it can affect your family’s daily routine and possibly make the house unsanitary. It’s important to know that the tank and its components are properly installed and protected from external conditions like parked cars and building projects. Many homeowners are unaware that building around or over the septic system can be detrimental to its structural integrity and functionality.

Can I Build on Top of My Septic System?

septic Mahopac NYWhile many homeowners decide to build a deck, patio, or addition, the project can pose problems if it’s constructed on top of the septic tank. People usually only realize their mistake when it’s time to schedule a septic pumping service. Covering the tank can prevent the technician from accessing it and connecting it to the pumping truck. As a result, the structure might need to be torn out. Similarly, building a new bathroom or utility room on top of the system can encourage sewage backups.

Can I Build Near the System?

It’s equally important not to build anything near the septic tank to avoid damaging the drain field, the area of the ground that absorbs and filters liquid waste. If any structure is placed over this field, it can compress the soil and prevent it from doing its job. 

Even temporary weight from lawn furniture or a parked vehicle can damage the septic lines. In severe cases of soil compression, you may need to move the drain field entirely instead of simply replacing it. This project requires a great deal of both time and money and might not be covered by your homeowners insurance. Marking the perimeter of the drain field with stakes or a lightweight fence can help you avoid this potentially costly and messy issue.
