A septic mound system can be a real eyesore in your backyard. Planting and props can be convenient ways to camouflage the mound so that it fits in better with your overall home landscape. Because of the ground conditions, special care and consideration must be taken when planting on or near your sewer system. Learn how to do it right so that upkeep is minimal.

Consult your local septic experts to find out what plantings are appropriate for your specific sewer system.

Decide what kind of grass, plants, shrubs and/or trees you want to plant to disguise your sewer mound. Choose grass or herbaceous plants for on the mound and trees or shrubs for around the mound.

Minimize soil contact by wearing gloves when planting on or near your sewer.

Cover the sewer mound with a minimum 6 inches of topsoil and a maximum 30 inches of topsoil. Avoid digging up the area, and limit erosion by minimizing tilling while establishing the cover.

Minimize root interference by planting plants with shallow root systems that do not like water or wet soil. Plant only herbaceous plants on top of the mound. Place trees and shrubs at the toe or base of the sewer mound, at least 20 feet away.

Allow the system to breath by limiting traffic on the mound and avoiding soil compaction.

Avoid irrigating the mound, so that its full capacity can be used for the disposal of septic tank effluent.

Camouflage the sewer cover with a decorative planter or mock rock.


A layer of grass can provide insulation and freeze protection for the mound.

Periodically check the sewer area for animal damage (such as burrows and tunnels) and take immediate action to remove any offending animals.


Do not plant edible plants on top of the sewer mound.
