no growth over septic tank - why not?

How deep is the lid? The soil may be too shallow to hold moisture. Or the backfill may be sand or clay and gravel with no topsoil.

A properly functioning septic tank does NOT have any gaseous local exhaust at all, so the grass should neither grow more or less there for that reason. How about sunlight? Got a big tree over that tank? If that's it, use grass seed that grows in shade.

Other than shallow soil, I would suspect herbicide as the most likely cause. Evidently someone didn't want grass to grow there.

Do you have any idea how many people have been killed or maimed when grass grew over septic tanks and caused them to explode?

None?

See? It's the silent killer. You've never heard of it. Grass seed manufacturers have kept a lid on this for many years. They don't want you to know!

Probably due to heat from the tank drying out the soil more than the surrounding area.

In the dry season the septic field/tank area is the only place I can get grass to grow.

Interesting theory. Could be tested by sticking a meat thermometer into the ground in various places, a few hours after the sun has set.

on my tank the dirt is not thick-deep enough to get ground moisture, when it drys thats it till next rain, by then grass is dead. you need alot more than 6" of dirt

...and cut down on the Jalapeno peppers and Sauerkraut. HTH.

Sounds like a place for a ground cover that'll put up with very little moisture. Don't know the web sites, but there are organizations that recommend plants for places like Los Angeles, which is (to the surprise of many residents) a desert.

I just use big rocks plus the tank is not in use any more
