Grass is generally the best choice for areas over a septic drainfield because it has shallow roots and helps prevent soil erosion while allowing water and oxygen to move through the soil. Other shallow-rooted plants may also be suitable, but deep-rooted plants should be avoided because their roots can interfere with the septic system and drainfield.

Trees and large shrubs should be kept away from your septic drainfield because their roots can grow into and damage septic components or interfere with the drainfield.

Keep the drainfield area accessible and free from heavy use.

Vegetable gardens should not be planted over or near the septic drainfield.

Keeping the area covered with appropriate shallow-rooted vegetation is a safer option.

Items such as wipes, diapers, paper towels, feminine hygiene products, medications, chemicals, paint, and hazardous materials can clog or damage your system and may interfere with wastewater treatment. Even products labeled "flushable" can cause problems and are better disposed of another way.
