ᐅ Is it possible to install wastewater drainage in the basement?

Hello,

I am planning to build a new single-family house with a basement. My question is whether it is possible to drain the wastewater from the basement directly into the sewer system without the need for a lifting station. Specifically, I am wondering if the sewer is deep enough. The basement is planned to have a clear height of 2.5 to 2.7 meters (8.2 to 8.9 feet), and the basement ceiling should be at ground level. However, I cannot determine this from the sewer plan (126/7). It would be great if someone could help me with this and explain a bit. Are any other details needed? This is only a cross-section from the zoning plan, not from my house.

Thank you very much

What does your architect say?

I’m not at that point yet. But someone should be able to make an estimate based on the plans.

It probably won't fit.

Hello

No, that won’t work.
Pipes located below the backwater level must be drained using lifting stations.
The backwater level corresponds to the manhole cover at the street.

Hello, thank you. At what height is the backflow level or what exactly are the specified values? Because I heard that in this residential area the sewers are very deep, but according to the plan that does not seem to be the case.
