Hi,
We have a septic tank and the top is exposed and slightly above the level of the lawn. I want to blend this in with the garden. I have a few questions:
1. I know i'm supposed to leave the 2 pipes on top exposed but can I plant a rockery or something on it? is there a weight restriction?
2. When it is emptied is this done through the pipes or do they need access to the top of the tank?
3. How far from the septic tank and percolation area should I plant fruit and veg?
Thanks

"I know i'm supposed to leave the 2 pipes on top exposed but can I plant a rockery or something on it? is there a weight restriction?"
I have seen many lowish rockerys created on top of septic tanks. The concrete top of a tank should be able to take a certain amount of weight within reason (no large heavy rocks). For example, it takes the weight of the average person standing atop it.

"When it is emptied is this done through the pipes or do they need access to the top of the tank?"

It is not done through the pipes, instead it is through the access caps (man holes) on the main tank.

"How far from the septic tank and percolation area should I plant fruit and veg?"

As far as is possible for yourself. Although the percolation area sould be safe for growing in, you never know. I would have a fear of E.coli Bacteria and the like if your septic system is working incorrectly. Growing veg in raised beds will prevent their roots entering ground water.

Not that trees are important, but do you have any suppliers of tree root barrier panels in your area?

Bamboo root barrier by the roll can be effective near septic areas too.

That's in case anybody wants trees a bit closer and needs to block the lateral root growth.

It merely slips into a trech and the soil is backfilled. It's a sheet on edge.

Hi,
I know it's a very old post but I don't want to start a new one about the same issue.
My question is how far from a septic tank can you plant an ornamental tree? Is 3 m for a sumac (Rhus typhina or maybe Rhus glabra 'Laciniata' if I get it) enough? Would roots of any type of tree planted too close to a septick tank damage it's walls?
Thanks

Would imagine so, especially the old type (Brick) I read somewhere that in some trees the height equals the spread of the root. Would"nt chance it meself. P.S. have a look under "Irish trees and other ect. James kilkelly has a post with photo of a tree and roots exposed. see under "What is a tree ect.

This is not binding advice, so follow it at your own peril.
All i know is personally I would chance planting Rhus typhina or Rhus glabra 'Laciniata" 3 m from a septic tank.
Although the roots can be quick growing on these shrubs/trees, I have found that they are quite soft.
Added to that is the fact that they are mainly surface rooters, as can seen by their suckering ability.

But then I would keep an eye on their root growth, and have the ability to horse them out if I felt they were close to causing problems.

Make of that what you will.

James, I also think Easyram should wait until his septic tank has been inspected and passed. Lord knows what rules these buggers are going to come up with.
