How do I hide my above ground septic tank?

The Do’s For Hiding Your Septic Tank

  1. Plant tall native grasses with fibrous roots around the opening to conceal the tank lid from view.
  2. Place a light statue, bird bath or potted plant over the septic lid.
  3. Septic tank risers and covers are an alternative to concrete and blend into green grass.

Why would land fail a perc test?

Less commonly, a site can fail because the soil is too permeable, allowing the effluent to reach the groundwater before it is fully treated. Very steep slopes are also unsuitable for a conventional leach field.

Can sewage treatment plants be installed above ground?

Applications. In short, above ground wastewater treatment systems are suitable for installation on any project type due to their versatility and flexibility. For domestic wastewater treatment applications, concrete systems can cater from 6 to 18 persons.

How much weight can you put on top of a septic tank?

1 to 2 feet (0.3 to 0.6 m) of soil shall be over the top of the tank. No more than one axle or two wheels shall be over the tank at any one time. The minimum concrete strength will be 5,000 psi (35 MPa) compressive strength.

Should septic tank lids be buried?

In most cases, all components of the septic tank including the lid are buried between 4 inches and 4 feet underground. Unless the septic tank has special risers that position the lid at ground level, you’ll have to dig for it.

How deep do you dig for a perc test?

two feet deep
Test procedure. A typical perc test consists of three or more holes dug about 30 to 40 feet apart in the proposed drain field area (see illustration). The holes are typically 6 to 12 inches in diameter and two feet deep, the typical depth of the trenches in a leach field.

What happens if you fail a percolation test?

Failing the percolation test If you still fail after that, you’d either have to discharge very well treated water to a watercourse (only an option in NI) or avail of a ‘zero discharge’ system (constructed wetlands that do not require emptying).
