Planting in and around a septic tank

Crea

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.
