How to Hide a Septic Tank

Updated February 21, 2017

Septic tanks treat wastewater from homes that have no access to municipal wastewater treatment systems. Typically, the septic tank sits in the yard of the homeowner below ground elevation. The access hatch or service door is usually exposed. Trees should never be planted around or on top of the septic tank, since roots will find their way into the leach lines and clog the drain field. Homeowners don't have to be stuck with an access hatch as a focal point in their yard, however.

Install a plastic riser over the access hatch for the septic tank.

Cultivate the area around the riser by hand with the garden hoe.

Plant annual flowers around the riser area. A flowerbed 18 to 24 inches wide will conceal the riser during the growing season.

Paint the riser a green colour to match the surrounding landscaping.

Transplant small shrubs around the edge of the septic tank. Keep the plant root systems away from the drain field lines. In most cases, a row of small shrubs 6 to 9 feet from the septic tank's edge will conceal the tank year round.

Warning

Never install a permanent fence around the septic tank. If the tank requires service, it will be necessary to have full access to the septic tank. In severe cases, the tank may have to be removed from the ground. This will mean removing the fence structure. Never plant a garden over the leach field. Excess water from irrigation and cultivation to the soil will compact the dirt around the leach field lines. This will cause the drain field to stop operating properly.
