Can you put gravel over a leach field?

Planting your Drain Field (aka Leach Field or Mound)
Plant cover is also important to reduce soil erosion. Covering your septic area with plastics, bark, gravel, or patio blocks set in sand won't give your septic system the same benefits as planting and is not recommended.

Also asked, what can you put over a leach field?

Herbaceous plants, such as annuals, perennials, bulbs and ornamental grasses are generally the best choices for use on a septic drain field. Ornamental grasses also offer the advantages of having a fibrous root system that holds soil in place, and providing year-round cover.

Similarly, can you play on a leach field? When you have a leach field with green grass and no puddles, you have a properly maintained septic system that is regularly pumped. When your sewer is clogged, your leach field will start to collect sewage water. When there is sewage water in the leach field, it is unsanitary for children or pets to play in.

Simply so, how much gravel do I need for a leach field?

typically, washed gravel, 3/4" to 2 1/2" (pretty big) gravel is placed for a depth of 12" under the drain line piping ("septic drain tile" in some references). The pipe is then covered by additional gravel to a depth of at least 2" over the top of the septic drain line before backfill is added.

Can I put dirt over my drain field?

It is not recommended to add any additional fill dirt over any drain field, and certainly not an additional 24". Drain fields are designed to work with 18" to 24" of coverage, unless they have been engineered to deal with special soil types.
