Fish pond over sewer line

[englewood]

Hello,

 

Im new to this forum and looking for some advice.

 

I want to build a fish pond in my garden, i have a man hole where i want to put my fish pond, i wont be buliding my fish pond directly over the man hole but about 6"s from it.

 

As the sewer line runs into my house underneath where i want to put my fish pond im worried about the weight on my sewer walls, my pond will be 1.5m x 1.5m x 1m deep = 2.25T Ton of water.

 

Will my sewer walls be ok with the weight?

 

"I have taken the man hole cover up and the sewer pipe leading into the house will only cover a small corner of the fish pond"
